Explanation:
Answer:B). Cell membranes are composed of a lipid bilayer.
Explanation: A membrane is a lipid bilayer that surrounds the cell. Lipids have two parts: the fatty acid chain (the tail) and the phosphate group (the head).
The phosphate head groups are polar, face outward and interact with the outside environment of the cell. The fatty acid chain is hydrophobic and nonpolar, face each other in the bilayer thus forming a hydrophobic fluid interior.
The hydrophobic nature of the bilayer interior makes the membrane to permit only nonpolar and hydrophobic molecules to pass through the cell membrane. This is the reason the membrane allows only molecules that dissolve in the lipid bilayer to pass through to enter or leave the cell.
large cells have more suface area so it will take the fluids and molecules entering a longer time. So they will have trouble moving needed materials in and waste products out. Hope this helped have a great day! :)
plz mark me as brainliest
Taking all of them out of their natural environments would disrupt the ecosystem and food chains, and it would be difficult, if not impossible, to place more than a small portion of Earth's endangered species in these facilities.
