Still, he says, it is an example of how flexible life is. "It lives in an area without oxygen and therefore can get rid of a lot of biochemistry that you and I would need in our cells to survive ...

These intestinal cells then migrate up the intestinal villi. During their migration, they perform a certain function, for example the absorption of nutrients or the production of hormones.

For example, they perform a necessary function for metabolism, the process of breaking down food and drink into energy. Enzymes speed up (catalyze) chemical reactions in cells. More specifically ...
