Клетки крови лопаются в чистой воде и сморщиваются в солёной. Почему этого не происходит, когда человек пьет много воды или потребляет пересоленную пишу?

Ответы

Автор ответа: icanfixthat

Эритроциты (красные кровяные клетки) устойчивы к изменениям в содержании воды и соли в организме. Они регулируют свой объем и форму, чтобы сохранить свою целостность. Пить много воды или потреблять пересоленную пищу обычно не вызывает повреждения или изменение формы эритроцитов.

ALEX’S SCHOOL-DAY

As for me, I sometimes think that I cannot live without my school and my classmates, but there are days when I would do everything to slip the classes. Let me explain.

For example, yesterday was a typical bad day. I came to school at nine. I overslept and was late for the first lesson. As the teacher of mathematics is very strict he wrote some unpleasant words in my day-book. Then we had Ukrainian. I am not good at learning rules and writing dictations and yesterday we had a test. Of course I failed it and got very upset.

Then we had a break. During the break my friends and I always play football in the gym. We all love running and kicking the ball and nobody likes to stand in the gates. Sure, I was a goalkeeper yesterday. Our team lost and it was all my fault.

After that we had a couple of classes of English. The teacher was explaining a new topic, so nothing bad happened to me. I skipped the last lesson. It was Biology, and I was not ready for it.

However, today was different. I got an excellent mark for a test in Physics, and my best friend invited me for his birthday. The lessons were all very interesting, and I learnt a lot of new things. After classes there was an excursion to the local history museum. We listened to the story about our town.

On the days like today I love my school and my teachers. I understand that teachers help us to learn about the world, and we should be very grateful to them.
