How do skin cells illustrate the idea that "form fits function" in specialized cells?
A.
The rectangular shapes of skin cells allows them to pack closely together to form a protective barrier.
B.
Because they are elongated, skin cells can connect to one another to transmit electrical signals.
C.
Because they are flat, skin cells can form a very thin layer that gases and nutrients can diffuse across.
D.
The large nucleus of each skin cell stores extra genetic material so that the cells can produce more proteins.
