If cells did not work together, what would happen to the organism?

Answers

If cells do not work together, the organism would die and the get extinct because there will be no cell division and no transfer of genetic material.

What are cells?

Cells are the tiny and basic units of life. The cells together form an organism. Cells are of two types, prokaryotic and eukaryotic cells. The eukaryotic cells contain a nucleus and cell organelles.

There are millions of cells in the body. All cells work together. Cells divide by cell division and form another cell. The division creates the organism. The cells are identical to each other. If the cell does not divide, the organism will not grow and eventually get extinct.

Thus, If cells do not cooperate, there will be no cell division and no genetic material transfer, which would result in the death and extinction of the organism.

Why does the earth not lose its heat as quickly at night as the moon does?

Answers

The Earth does not lose its heat at night as quickly as the moon because the Earth has an atmosphere. If you don't know what the word atmosphere means, another way of thinking about it is a blanket around the Earth; a blanket that we can see through.
This is because the moon is formed of rock and it can become cooler not like Earth surface of 70% water and 30% land.
