HELP ASAP if a molecule passes through a protein but goes down a gradient it is called
a. facilitated diffusion
b. exocytosis
c. active transport
d. endocytosis

I think it would be A. Facilitated diffusion

Explanation: I think it would be a cause some molecules can move down their concentration gradients by crossing the lipid portion of the membrane directly while others have to pass through membrane proteins in a process called facilitated diffusion

If im wrong srry!

Hope This helped!

The answer is facilitated diffusion

Explanation:

in cells,some molecules can move down their concentration gradients by crossing the lipid portion of the membrane directly, while others must pass through membrane proteins in a process called facilitated diffusion.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
