Question

Organisms must be able to adapt to a changing external and internal environment. An organism's ability to maintain a stable internal environment is known as homeostasis. How does a cell's membrane help an organism maintain homeostasis?

cell membranes directly control the temperature of the cell

cell membranes are porous and allow things to enter and leave the cell as they wish

cell membranes control the substances that enter or leave cells, making sure that levels stay within the range necessary for life processes to continue

cell membranes don't help maintain homeostasis, other organelles are responsible for that

Answer 1

I can eliminate A (temperature control is more complicated than that) and D (cell membranes are part of homeostasis, just not the full picture)

between B and C, which one do you think is better for maintaining homeostasis? just letting things go in and out willy-nilly or controlling the substances?

Answer 2

It would be C

Answer 3
