Question

How does the cortex of a typical animal cell differ from that of a mature red blood cell?

Choose one or more:

It allows the cell to selectively take up material from the environment.

It allows the cell to move.

It gives the animal cell a distinctive biconcave shape.

It is richer in actin and in the motor protein myosin.

Answer 1

ANSWER :

A cellular cortex is the network of contractile proteins that's rich in actin and motor protein myosin and bound to the plasma membrane of almost animal cells. It functions to allow the cell migration (or movement) & their division. However, these cellular adaptability are not present in mature red blood cells (RBCs). Hence statements (b) and (d) are correct.
