Which of the following forms of cellular transportation animal cells maintain na+/k+ level homeostasis?

a)diffusion
b)cell membrane pump
c) endocytosis
d) osmosis

The correct answer is B cell membrane pump.

Explanation:

Pumps can be defined as integral membrane proteins that carry out active transport of various solute molecules and ions against their concentration gradient through the requirement of additional energy in form of ATP from outside source.

    Na+K+ ATPase pump helps to maintain the normal homeostasis of Na+/K+ level by active transport system which requires energy in form of ATP.

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.

d. cellulose and starch
