Materials move within the cell 's cytosol by diffusion, and certain materials move through the plasma membrane by diffusion. ... Diffusion: Diffusion through a permeable membrane moves a substance from an area of high concentration (extracellular fluid, in this case) down its concentration gradient (into the cytoplasm). Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane.The cell membrane controls what goes in and out by having protein channels that act like funnels in some cases and pumps in other cases. ... Active transport requires energy, because protein machines actively grab molecules on one side of the membrane and push them through to the other side
Answer:
WHATS WITH THE <3 YOU PUT, I WAS GOING TO ANSWER UNTIL YOU PUT THAT THING ON THE QUESTION SO IM SORRY IF I DIDNT ANSWER ;-;
Explanation:
Answer:
plasma membrane/ cell membrane
I agree with the other one “The sperm whale has a diploid complement of 2n=42 and the killer whale a complement of 2n=44. These two species, though different in chromosome number, have karyotypes which have no t group chromosomes and more m group chromosomes than the typical whale karyotype.”
Umm where is the questions ?
