“FROZENS FROM A BARREL”

Conditions: teams take turns drawing tokens with numbers from the “barrel” and answering questions under these numbers. If a team gives an incorrect answer, other teams can give their answer and, if it is correct, earn extra points.

Score: 2 points for each answer.

1. Which mammals store fat? What features of their life is this connected with?

(those that hibernate; those that go without food and water for a long time - camels; aquatic - increased buoyancy, protection from hypothermia)

2. Which mammals have a keel and why? (bats - for attaching flight muscles; in moles - for attaching powerful pectoral muscles)

3. Why does a whale that lands on land die within a few hours? (from overheating)

4. Why is the fat of a camel concentrated in the humps, and not evenly distributed throughout the body, like in whales? (otherwise the body would overheat)

5. What is the significance of molting for the white hare?

(winter cover is thicker and warmer and gives camouflage coloring)

6. Cats take more care of the cleanliness of their bodies than dogs: they wash themselves and diligently lick their fur. How can this be explained?

(the smell gives them away when they are guarding prey)

7. Zoologists have always dreamed of having exotic animals in zoos, in particular the well-known koala. However, it turned out to be impossible to transport, much less keep him in captivity. Why? (koala eats eucalyptus leaves, but it doesn’t grow everywhere)

8. About a hundred years ago, 5 rabbits were brought to Australia. Years passed, and their millions of offspring began to cause colossal damage to the fields. Explain the reasons for such a negative result of animal acclimatization.

(there were no predator rabbit population regulators in Australia)

9. Many animals mark their territory, for example, a deer has scent glands on its face. What does this mean for animals?

(fight for territory, distribution of space)

10. Some bats spend the winter in caves, accumulating there in large numbers. What does this mean to them? (this is how they warm each other)

11. Often in children's cartoons and fairy tales the hare is called oblique. Why was he called that?

(for the ability to always dodge to the side when running)

12. The hedgehog and the mole belong to the same order of insectivores. But the hedgehog hibernates, but the mole does not. What explains the differences in the life activities of these mammals?

(the mole feeds on underground insects, and the hedgehog eats on land)

13. Why are hares’ cubs born covered with fur and sighted, while rabbits’ cubs are naked and blind? (in rabbits, cubs are born in a deep hole and are protected from enemies)

14. An elephant can uproot trees with a diameter of 25-30 cm and plow the ground.

What tool does he use? What are its features? (tusks and trunk)

15. Monomakh’s hat, one of the symbols of autocracy in Russia, is trimmed with the fur of this animal. (sable)

"AUCTION"

Assignment: each team receives a postcard with an image of an animal; the opposing teams, using leading questions, must guess which animal is depicted on the postcard. The team that gives the correct answer receives points.

Rating: 5 points.

"BLACK BOX"

Conditions: teams listen to the task, and the team that first raised its hand when reading the task answers. If the answer is incorrect, other teams can answer.

Rating: 5 points.

This animal is familiar to us and is very similar to us. Although for some, comparison with him may seem offensive. Its heart, lungs and digestive system are so similar to human ones that in the future they can be used for transplantation into humans.

Heart valves are already in use today. These animals, communicating with their fellows, emit 23 sound signals. The structure of their skin is amazing. It has the ability to tan and can be used as a dressing for burns. Under this unique dressing, the patient's own skin forms faster. The animals we will talk about distinguish colors. Like people, they love cleanliness and adore beer. They enjoy searching for mushrooms and are not afraid of snake bites.

Scientists consider them to be among the most intelligent animals. Moreover, one of their representatives was awarded the rank of officer because she easily found drugs.

What animal is in the “black box”?

(pig - you can use a stuffed toy or a drawing)

Open biology lesson "Mammals Class"

Lesson objectives:

    Summarize and systematize students’ knowledge about the main orders of Mammals; their adaptability to habitats; meaning in nature and human life.

    Continue the development of intellectual skills: highlight the main thing, establish cause-and-effect relationships.

    Continue the formation of cognitive interest in the subject through the use of non-standard forms of education and the creation of a situation of success, contribute to the cultivation of a culture of communication.

Equipment: a set of postcards and drawings depicting various representatives of the class Mammals, video equipment, slides.

Lesson type: unconventional.

The class is divided into several groups.

During the classes

I. Organizational moment .

Goal setting: recall the studied orders of the class Mammals, the characteristic features of animals of these orders, adaptability to the environment, their significance in nature and human life. Identify similarities.

Repetition of knowledge. Assignment for groups.

Task No. 1.“Seven-flowered flower” (a flower is pasted on a board made of colored paper, students tear off the petals, on which the names of the orders of Mammal animals are written on the other side)

It is necessary to characterize the detachment according to the plan:

a) representatives;

b) environment and habitat;

c) characteristic features, adaptation to the environment;

d) significance in nature and human life;

d) interesting facts.

Task No. 2.“Who's the odd one out?”

Zebra

killer whale

Seals

Hare

Task No. 3. "Who is this?"

Guess the riddle, indicate the name of the animal and the order it belongs to:

a) “The Miracle Yudo Giant is carrying a fountain on his back.” (Elephant, Proboscis)

What is his fountain like? (The whale breathes atmospheric air. The act of its breathing occurs after emerging from the water, every 10-15 minutes. Exhaled water vapor and splashes of water from the surface of the sea form a fountain above it.)

b) “In rich clothes, but he himself is somewhat blind, lives without a window, has not seen the sun.” (Mole, Insectivores.)

What are the features of its fur due to its lifestyle?

(The mole's fur consists of one undercoat. It is very thick, short and velvety. The mole's hair only grows straight, which does not prevent it from moving in any direction. The fur protects the mole from dampness, cold and dirt.)

c) “What kind of forest animal is this, stood up like a post under a pine tree and stands among the grass - ears larger than head?” (Hare, Lagomorpha)

What is the significance of ears in a hare's life?

(The fast running of a hare is associated with intense work of skeletal muscles. At this time, excess heat is formed in its body, which can lead to overheating. Without sweat glands, hares regulate temperature and transfer heat through the large surface of the ears.)

d) “Who was born with a mustache?” (Cats. Predatory.)

What role do they play? (Long, coarse hairs are not whiskers, but vibrissae. They are located on the cat’s face, near the eyes, nose, on the upper lip and perform a tactile function.)

Task No. 4. “Why are they interesting?”

Solve the riddle. Give interesting facts from the life of these animals.

a) “This beast is familiar to you: as tall as a mountain, as tall as a house.
Ears on the air, hand on the nose.” (Elephant. Proboscis.)

b) “He likes to climb vines, eat grapefruits and bananas,
Makes kids laugh from ear to ear.” (Monkey. Primates.)

c) “All my life I’ve been wearing a vest,
But without boots and without a cap.” (Zebra. Odd-toed ungulates.)

d) “A cat walks and wanders along the forest paths.
This wild pussycat has two tassels on her ears.” (Lynx. Predatory. Felines.)

Task No. 5."Find yourself."

The orders of animals of the class Mammals are written on the board; students must select from the proposed drawings and place representatives of these orders on the board. (Pinnipeds, Carnivores, Rodents, and so on.)

Task No. 6.“Give me a word.”

Fill in the missing words in sayings and proverbs.

a) “From black…. White milk.” (ladies)

b) “And the shepherd and the wolf…. guard.) (sheep)

c) “…..in the yard, so is the food on the table.” (cow)

d) “From ...... there is a lot of squealing, but no fur.” (pigs)

Task No. 7 “What animals are the monuments erected?”

(In Rome - to a donkey toiler, in Paris - to a Serbernard who saved 41 people in the Alps; in Bergo San Lorenzo (Italy) to the dog Verny, who for 14 years went to a stop to meet his owner who died in the war; in St. Petersburg - to a dog serving science.)

Conclusions and generalization:

Animals of the Mammals class settled everywhere and adapted to all living environments, since they have a very high organization compared to other representatives of the animal world. And no matter how different they are from each other, they have the following common characteristics:

    hairline;

    body temperature is constant, the heart is four-chambered;

    viviparity, feeding babies with milk;

    well-developed brain, complex behavior.

Explanation of a new topic
Hello!
Today we will take a journey through the ocean of knowledge to the country
which is not on the map, but with some residents of this country you are fine
are familiar, and you have to find out about the rest. What kind of country are you supposed to
guess by answering the following question.
Attention! Mysterious stranger. I have in my hands a description of one
very interesting creature. Your task is to guess who we are talking about. Not
hurry up with conclusions! All versions are after listening.
This animal is familiar to us and is very similar to us. Although for whom
then comparison with him may seem insulting. Heart, lungs and
His digestive system is so similar to that of a human that in the future
can be used for human transplantation.
Heart valves are already in use today. These animals, communicating with
their brothers, emit 23 sound signals.
The structure of their skin is amazing. She has the ability to tan, her
can be used as a dressing material for burns. Under this
With a unique dressing, the patient’s own skin forms faster.
The animals we will talk about distinguish colors.

Like people, they love cleanliness. They like to find mushrooms and they don't
afraid of snake bites.
Scientists consider them to be among the most intelligent animals. Moreover, one of them
the representative was awarded the rank of officer because she easily
found drugs.
So who is she?
This cute pig (the teacher takes out a toy) will
mascot for today's lesson. But why suddenly today I started talking about
this creature?
That's right, new topic. "Class Mammals, or Animals."
Studying this topic lays the foundation for the study of biology in 8
m class, which means you must be very attentive and diligent.
So, which country will we travel to?
+ To the country of Mammals, or Beasts.

Around as far as the eye can see,


Mammals, or Beasts, have interested people since ancient times.
The famous Swedish scientist C. Linnaeus in his “System of Nature”
(1758) listed only 86 species of mammals; today science knows
about 4500 species of these animals.
Today is the first lesson on the topic, and its purpose is the most general acquaintance with
class of mammals.
For the first acquaintance, out of more than 4,500 species, I chose only 4 animals.
I didn’t choose it by chance, but with a certain intention.
Your task is to solve it.
One of the best diggers. The wool of this one is very interesting
animal: it is very short, thick, smoothes out in any direction and
changes up to 4 times a year.
+ Mole.
Perfectly navigates in absolute darkness thanks to the unique
echolocation system. They are excellent flyers, capable of flying
distance up to 1000 km.
+ Bat.
Who jumps on his hind legs,
Is he hiding his son in a warm bag?
Who, standing up to his full height,

Does it rest on its tail?
+ Kangaroo.
The animal's head ends with the famous "beak" resembling
duck The beak is covered with skin rich in nerves and special receptors,
sensitive to weak electrical impulses. Such impulses
occur during the movement of aquatic invertebrates on which it feeds.
+ Platypus.
Please draw a conclusion.
What did I want to show you?
+ Diversity of habitats, they inhabit all living environments: air
terrestrial, water and soil.
General characteristics of the class Mammals, or Animals.
1. I know mammals
Both pleasant and frightening,
Cute and terrible
Harmless and dangerous
Carnivores, herbivores,
Dirty and neat,
Shaggy, bare-skinned
And they look like people.
2. Mice and dogs,
Cows and elephants
Crumbs and animals
Large size.
They have a lot in common -
They are viviparous
They all feed
Children with milk.
3. Around as far as the eye can see,
The crown of creation is the highest class,
Prosperous creatures are mammals.
4. Mammals have a very delicate sense of smell,
Vision and hearing are well developed.
5. In mammals, all without exception,
There is hair
And a tendency to go bald.

6. Body temperature is a big deal.
Helps the animal survive
Warms him from the inside
In cold water, on hot sand,
On an ice floe, in a swamp and even in the ground.
7. There the covering is hairy, silky and thick,
And mine is colorless, rare, unnoticeable.
The most common mammals that we know from childhood are terrestrial
animals running on 4 legs (mice, cats, dogs, horses.) But is it possible?
Doesn't the duck face of a platypus or the flight of a bat resemble birds?
Are aquatic animals (dolphins and whales) with their appearance and fast swimming
don't they look like fish? Scaly cover of pangolin lizards, shell
armadillos, echidna quills, hedgehogs, porcupines are also examples
diverse and amazing appearance of mammals.
What explains the diversity of animals? Apparently, because they
ancestors for many millions of years adapted to different
living conditions; as a result, only the most
adapted from them.
Mammals also differ in size. The smallest animal
The shrew is a baby weighing 2 g, and the largest animal of all when
or a blue whale weighing 150 tons who lived and lives on Earth. Blue whale
65 million times heavier than the baby shrew.
Animals have varied habits and lifestyles. For example, in the echidna and
platypus babies hatch from eggs; in kangaroos and other marsupials they
are born underdeveloped, and in hares and mice newborns are helpless,
weak, blind. At the same time, in many animals (proboscideans, equids)
Soon after birth, the cubs can stand, walk, even
follow your mother.
There are many mammals known to stay awake all year, but there are many
those that spend six months in hibernation.
What unites such different people into one systematic group?
animals?
Give a general description of mammals.

Conclusion: Mammals are viviparous animals that suckle
their young with milk, the body of most of them is covered with hair
cover, very well developed nervous system, jaws with teeth,
ability to regulate body temperature. Mammals are the most
highly organized group of vertebrates
2. Game “Biological shooting gallery”.
55 points – excellent. (5).
54 – 50 – marksman (4).
49 – 40 – a good shooter. (3).
Less than 40 – no big deal. (2).
The question number indicates the amount of points you will receive if you answer it.
right.
1. How many circulations do mammals have? (1 point).
2. How many chambers are there in the heart of mammals? (2 points).
3. Mammals have a closed circulatory system. What circulatory
is the system called closed? (3 points, etc.)
4. In what conditions do mammals live?
5. What sense organs in mammals have achieved significant development?
6. Mammals are warm-blooded animals. What animals are called
warm-blooded?
7. What did the ancestral forms of mammals eat?
8. What ensures better safety of young animals in a diverse
environment?
9. How many vertebrae are there in the cervical spine of mammals?
10. Is the statement true: “Caring for offspring leads to a reduction
fertility in animals." Prove your point.
I’ll unfold the Red Book,
(A very “thick” book at that)
And, having looked closely, we are amazed
How many lives do we have behind us?
Insects, birds and fish,
There are countless warm-blooded ones.
But we could
Save and save from death.

And it’s not for nothing that there is science on Earth
On the protection of the natural environment.
Ecology is an important thing
We couldn't have done it without her...
We study the life of organisms,
Their adaptation to the environment,
And also the human factor,
As a threat to everything on Earth.
I hope a miracle happens
Humanity will soon understand
Extinction of living organisms
And it also leads him to death.
We can't breathe carbon
Car exhaust pipes
And drink polluted water
Mining from various depths.
And systems of natural communities
Irreversibly destroyed
The planet's climate is changing
This is what we have come to today.
Studying this science
We find solutions to problems
So that children cannot know
What is Earth pollution?
I am very glad that you and I successfully returned from our trip.
We took a close look at the life of Mammals, or Beasts, and
we saw a lot of interesting things there that an indifferent person would not notice,
loving nature.
And you don’t need to go to distant countries to look at wonders.
Very interesting animals live around us.
Study nature carefully, look closely at everything - and you
you will be able to discover many different secrets of nature.
Homework: read paragraph 51 of the assignment in your notebook.

Lesson objectives:repeat and systematize knowledge about the structure and life activity of mammals, their relationships with their environment, the role of these animals in nature and human life.

Equipment:stuffed animals, skeletons, tables “Type Chordata. Class Mammals", "Type Chordata. Blood circulation patterns of vertebrates", "Type Chordates. Schemes of the structure of the brain."

The game involves two teams. The winning team is determined by the sum of points. The game is conducted by the presenter. Scientific consultants (2-3 people: teacher, strong students) determine the correctness of the answers. The points are calculated by a panel of judges. The game includes 5 games.

I. Lucky case".

The playing field is divided into 6 sectors: 1 sector - “External structure of animals”; Sector 2 - “Internal structure of mammals”; Sector 3 - “Behavior and Reproduction”, Sector 4 - “Diversity of Mammals”; Sector 5 - “Ecological groups of animals”; Sector 6 - “Diversity of mammals”.

Players are offered questions of two categories, differing in difficulty level. Each sector has questions both simple and complex. For a correct answer to a simple question the team receives 1 point, for a difficult one -

2points.

The sector is determined by rolling the dice; students choose the question number themselves.

External structure of animals

1.Why does a dog stick out its tongue in extreme heat?

2.What is characteristic of the external appearance of a mammal?

3.How does the skin of mammals differ from the skin of reptiles and birds?

4.What is the structure and role of hair? Why is it not developed in whales and dolphins?

5.There are no fatty or sweat glands on the cat's body, and it does not salivate when it sees prey. Felines have a flexible spine and strong hind legs. The cat's sense of smell is poor, but its hearing and vision are good. What significance do these features have for the animal?

6.Is there a change in fur in animals? If so, what significance does this process have in the life of an animal?

N. Kondratkovskaya.

Today we are beginning to study one of the most interesting classes of the animal world - the class of mammals. This class represents the most highly organized vertebrates, which appeared 160 - 170 ml. years ago. The appearance and size of mammals are very diverse - from dwarfs (4cm - shrew) to giants (blue whale - 33m). There are five and a half thousand species of modern mammals, they have spread widely across the globe and have mastered various habitats: land-air, soil, water, and some in the air (the largest flying animal on the planet is the kalong, a large flying fox. Wingspan 1. 4m).

Watch the video clip “Animal Habitats” Gallery. Video fragment No. 90.

“Who wants to evoke mutual

friendship and trust, he must try

study its features, character and habits...

and he will be rewarded with what he gains

friend" Alfred Bukovets

  1. Indicative-motivational stage

Over the course of several lessons, we studied the topic “Class Mammals”, got acquainted with the features of the external structure of mammals, studied the diversity of orders of this class, their characteristics and representatives. The topic of our lesson today is “Diversity of orders of the class mammals. Generalization of knowledge"

The class of mammals includes about 4 thousand species, they are very diverse: the largest animal is the blue whale, its body length is 30 m, weight - 130 tons. The smallest animal is the Etruscan shrew, its body length (including the tail is 7 cm, and its weight is only 2 g.

Let's rememberWhat characteristic features do representatives of the class mammals have?

  1. Viviparity and feeding of young with milk, care for offspring.
  2. They have hair.
  3. Highly developed nervous system, complex behavior.
  4. The circulatory system is closed, the heart is four-chambered, there are two circles of blood circulation.
  5. Warm-blooded, constant body temperature.
  6. The cervical spine has 7 vertebrae.

There are about 4 thousand species of modern mammals. They are widely distributed around the globe, living in a wide variety of conditions.

Now we will watch a video clip and answer the question: What living environments have mammals mastered? Viewing the video fragment “Mammalian Habitats” (gallery, video fragment No. 90 “Animal Habitats”)

  1. Operational and executive stage.

Working according to a logical diagram"Mammal Habitats"

Environmental conditions

Warm-blooded

Logic support diagram questions.

- What ensures the existence of mammals in different living environments?

How did different environmental conditions affect animals?

The diversity of living environments and the conditions of these environments have led to great diversity among mammals. Placental mammals include about 20 orders, representatives of which are widespread on our planet. Now you will test yourself how well you know representatives of various orders of mammals and their characteristic features.

We conduct a biodictation. When performing a biodictation, we show various mammals in a presentation, during which students fill out the “Name of the Animal” column, then we give time to fill out the remaining columns of the table.

Characteristic features of the squad

The editors of the magazine “Young Naturalist” received several notes from Dunno about the life of animals.Read these notes carefully and highlight in the text those mistakes that the author made due to his ignorance.(Texts are included in the student’s individual sheet of options)

BEARS (bears), a family of mammals of the primate order, the largest of modern predatory animals; includes 8 types.

The body length of modern bears is 110–300 cm, height at withers up to 135 cm, weight up to 700 kg. The body is powerful, with high withers. The neck is thick, usually long, the head is large, with an elongated facial region, the eyes are small, and the ears are round. The paws are strong, plantigrade, three-toed. The tail is short, almost invisible. The fur is tall and sparse. The wool is colored black, brown or white, changing with the seasons.

Distributed in Europe, Asia, North-West Africa, the Arctic, North America, and in the mountainous regions of northwestern South America. All types are terrestrial. They live alone or in families. Active only at night. Most lead a sedentary lifestyle, while some wander widely. They do not hibernate. Omnivorous. They prefer to eat plant foods: berries, fruits, nuts, also insects, fish, and less often large animals.

The life expectancy of bears is 30–45 years. Many species are well trained and kept in zoos.

DESERT ZEBRA (Grevy's zebra) is a species of artiodactyl mammal of the equine genus; the largest of the zebras. The light coloring of the belly rises quite high on the sides, the stripes are wide. The hair forming a brush at the end of the tail is relatively short. The cry of Grevy's zebra, more than that of other zebras, resembles the cry of a horse. The desert zebra is common in the central parts of Eastern Ethiopia, Somalia and Northern Kenya, as well as in the semi-deserts of Eurasia. It lives in wooded areas and semi-deserts, where it prefers gentle mountain slopes and plateaus; in Kenya it sometimes forms mixed packs with savannah zebra. The number of desert zebras is about 15 thousand.

CHEETAH, a mammal of the cat family, order of lagomorphs.

It has a dry, lean body 123-150 cm long, with a large head and long and slender legs. The long, strong tail (up to 75 cm) acts as a balancer when running. The fur is short and sparse. The general color tone is yellowish, sandy, there are no spots.

Distributed in lowland deserts and savannas of Europe and Asia. There are known references in Russian chronicles to the beast pardus, whose descriptions are similar to a cheetah.

The slowest animal of all mammals. When catching up with prey, it can reach speeds of up to 110 km/h over short distances. It hunts mainly during the day or at dusk, sometimes lying in wait for prey at a watering hole. It feeds on ungulates and, as additional food, on hares, small animals and birds. There are 2-4 cubs in a litter. Found alone or in pairs. Cubs (1-4) are born sighted and spotted.

In India and Western Asia it was previously used for hunting antelope. Few in number. Easily tamed and reproduces in captivity.

We check the completion of the task, correct the mistakes made by Dunno.

We look at the video fragments “Forest Mammals” (gallery, video fragment No. 31) and “Mammals of open spaces” (gallery, video fragment No. 40)

Here are images of various animals. All of them are made by the artist. An artist who professionally draws animals is calledANIMAL PAINTER. And the style of depicting animals in art is called animalism. The artist Malyavin painted a “portrait” of the animal, he tried to depict a hare.

What mistakes did the artist make? What animals are the parts mixed by the inept artist?

The fauna is influenced by human activity, which leads to the reduction or destruction of some animal species. Since the beginning of the 18th century, 63 species of mammals have disappeared on our planet, which is 1.5% of their total number.

The main reasons for the impoverishment of the Earth's fauna are:

  1. Hunting
  2. Habitat destruction
  3. Reduction and deterioration of food supply

To preserve endangered animal species, reserves and reserves are created, and the “Red Book” is published. The Red Book of Russia includes 54 species of mammals.

LEOPARD

Hunters caught a leopard

On the banks of the Naryn River

He didn't growl, he smiled

When he showed his fangs...

But people dug up the ground.

They achieved their goal

He was strong, but about traps

He didn't know anything yet.

He understood. He gave in proudly

When the Kazakh knitted it,

And it was gloomy and bitter

In his orange eyes

He watched people with squinting eyes

They made him sad

Anger and generosity blazed within him,

And the tail darted across the sand.

He settled in the zoo

Where there is a lot of meat and water...

He is cherished there diligently.

He submitted. He's lying down.

And you can only see how the heart

His spotted fur trembles.

/ B. Akhmadulina/

How did reading this poem make you feel?

It is within our power to do everything to ensure that the animal world does not become scarce and is preserved.What can each of us personally do to preserve the diversity of the animal world?

Mammals are of great importance to humans. The domestication of horses and cattle ensured the long-term prosperity of human society. Livestock husbandry and hunting and commercial farming are the most important sectors of the modern economy, providing humanity with protein products. Rare species need protection. There is a fight against mammals that harm crop plants, food supplies, and carry pathogens.

Rating scale

Less than 8 points.The attitude towards animals is indifferent and selfish. You don't care about the fate of the animals around you. Perhaps you have never had your own pet at home and it is difficult for you to imagine that an animal can become a true friend. Get a hamster, cat or dog at home and you will see that each creature will certainly reciprocate your feelings.

From 8 to 14 points.Little conscious and inactive attitude towards animals. You communicate with animals, but have little interest in their lives, habits and concerns. Watch the most common animals, and you will be able to learn a lot of interesting things, you will see that you have more friends, it has become easier for you to communicate. And, besides, you can trust your pet with your secrets and secrets. Rest assured, they will remain between you.

From 15 to 20 points.Correctly conscious attitude towards animals. You must have thought about your attitude towards animals. Most often, you act wisely towards our smaller brothers, and they, in turn, are grateful to you. You must become an example for others. Together with your friends, you will be able to discover the secrets of the animal world and share your discoveries with others.

Over 20 points.You overestimate your attitude towards animals. Perhaps you are characterized by excessive emotionality, and therefore you idealize the importance of animals in your life and the lives of those around you.

Task No. 2Read this note carefully and highlight in the text those mistakes that the author made due to his ignorance.

BELYAK (white hare), a mammal of the family of hares of the order of rodents. The body length of the hare is 50-60 cm, sometimes up to 75 cm, weight up to 5.5 kg. It got its name from its snow-white summer fur.

The hare is found in forests, tundras and deserts throughout Northern Eurasia - from the shores of the Arctic Ocean to Mongolia, as well as in the north of North America. The white hare is also acclimatized in South America. In temperate latitudes, female hares usually give birth to 2-5 babies once a summer. In the north, hares breed once a year, but the litter size is larger - 6-9 hares. The white hare, although it has valuable fur and meat, is not a commercial object.
