#13
How do cells maintain homeostasis through membrane transport processes?
By increasing membrane permeability
By minimizing membrane fluidity
By regulating the movement of ions and molecules across the membrane
By decreasing the number of transport proteins
#14
What is the primary function of the sodium-potassium pump in animal cells?
