(508) Interesting animal-kitten (1)

We have finished learning the first unit of our Chinese textbook, and there is an oral communication assignment, which is a picture. According to this picture, we can communicate with our classmates what kind of animals we like and where they are interesting.

There are many small animals in the picture, including snakes, kittens, puppies, giraffes, pandas, chameleons, lions, fireflies, snails, rabbits, sika deer, parrots and foxes. I think these little animals are very interesting. Dogs are good friends of human beings, parrots can imitate human speech and so on.

But I think kittens are more interesting. It has a furry body, especially gentle and lovely. Besides, I also heard the teacher talk about the difference between a female cat and a male cat. After the mother cat is born, her parents can dye her cells. Her father's chromosome is XX and her mother's chromosome is XY. The birth of a kitten baby mainly depends on the mother, because the mother has two different chromosomes and the father has two identical chromosomes. If her mother gives her a Y chromosome, the baby is XY and the cat's feathers are two colors.

Everyone's questions are coming again. What about the pure white cat? That's because there is an albino substance in cats, and birch will make the color of stained cells invisible. In fact, this kind of pure white cat still has color. Some cats don't live long and die at birth. Why? Because some cats have an extra chromosome, normal cats have two kinds of face chromosomes, but this short-lived cat does have three colors, because there is something wrong with its chromosome planning. How did this happen? Because it has a chromosome in its body, which greatly affects its life span. Some cats are born dead, some cats are born alive, but eventually they will soon enter a state of death.

Will we be afraid? Don't be afraid, because there are only two kinds of chromosomes in the human body. Oh! There is one more thing to say. Cats contain an amino acid. You know why it likes to eat fish. Cats eat fish mainly to supplement amino acids in their bodies, because their eyes can see food clearly by amino acids at night, because this amino acid will make her eyes shine when catching prey. With this light, it can see more clearly at night, five times as much as ours, and its beard can also measure the size of the hole and detect it.

From what I know, everyone knows kittens!
