By controlling what enters and leaves a cell, the cell membrane A) aids in maintaining homeostasis within the cell. Homeostasis is the process by which organisms maintain life through eating, growing, and living in variable conditions. It would not make sense to answer B) because organisms do not control the homeostasis of their external environment. D) also would not be correct because cell's do not control osmosis in the external environment. The membrane does not control osmosis because osmosis is generally a random process of molecular diffusion whereas the membrane acts in a conscious and controlled way.

I'm pretty sure that would be the spinal cord. Hope this helps. :)
Answer:
E, A, C, B, D
Explanation:
Your weight is the force of gravity pulling you towards earth. A push or pull is a force. Gravity pulls everything down towards Earth. Friction slows things down like a ball rolling. If there was no friction a ball would roll forever. When you push on a door you contact it while using a force, contact force.
