How do the trillions of cells in the human body get what they need to function, and what do the cells do with the things they absorb? Please write a paragraph or more than 20 words :)

Sagot :

The human body is composed of trillions of
cells. They provide structure for the body, take
in nutrients from food, convert those nutrients
into energy, and carry out specialized functions.
Cells also contain the body's hereditary material
and can make copies of themselves.
