What is cell.
a proper answer would me

Explanation:

The cell is the basic unit of every living being that has the right machinery for vital processes. Some sectors of the cells can be observed under the optical microscope (nucleus, cytoplasm and plasma membrane).

There are 2 types: eukaryotes (they have nucleus inside the cells) and prokaryotes (no defined nucleus).

an adaptation is a change or process by which an organism takes to be better suited for its environment. for example; migration is a behavioral adaptation, this is needed because birds are not built to last extremely cold climates. there are different adaptations because there are different species needing to adjust to different things, bears don't migrate; they hibernate.
