Nonpolar and small polar moleculescan pass through the cell membrane, so they diffuse across it in response to concentration gradients. Carbon dioxide and oxygen are two molecules that undergo this simple diffusion through the membrane. The simple diffusion of water is known as osmosis.
When blood flow to the brain is interrupted, less oxygen and glucose reach the brain. This causes brain damage and neurological problems.
<h3>Blood flow to the brain</h3>
Blood circulation in the brain has an important function in maintaining brain health. Blood circulation provides the brain with the oxygen and nutrients it needs to function properly.
Blood carries oxygen and glucose to the brain. The brain makes up only a small part of your total body weight, but it requires a lot of energy to function. The brain uses about 15% of the oxygen and glucose the body needs. In short, blood flow to the brain is a very important factor in maintaining brain health. If this cycle is disrupted, the brain can be damaged. As a result, many diseases and disorders related to nerve function can occur.

If you are going from a high gradient to a low gradient it’s passive transport. Think of a hill if you put a rock at the top of that hill it will go down no energy involved. Active transport is going up the hill you must use energy to push that rock up the hill because it’s from a low gradient to the top. Hope this helps
C. The organism is a prokaryote
Cuz prokaryotes don't have a nucleus
plant and animal cells are eukaryotes which has a nucleus
