Well to move they need help from the muscles, because by their own they are just like a bunch of sticks
Answer:
it depends on the type of the cell.
Explanation:
Prokaryotic cells have internal folding of the cell membrane which are responsible for certain functions like respiration. These foldings increase the surface area.
Eukaryotic cells are compartmentalized which is a method to increase the surface area as there are lots of membranes inside the cell across which many processes take place.
In some cells like the ones making the lining of the villi in the small intestine there are folding in the outer cell membrane which also increases the surface area,
Answer:
Lynx, like other forest hunters, play an important ecological role. As a mid-size carnivore, lynx target smaller prey species that reproduce relatively quickly. When the lynx become fewer, they catch fewer hares. Thus, the number of hares increases, and the cycle repeats itself.
Explanation:
Answer:
Atherosclerosis would be the occlusion.
What anastamosis is maintaining blood supply to the brain and by what routes?
●Collateral Circulation
●Collateral Willis
Explanation:
Atherosclerosisis affects arterial blood vessels by causing a thickening of the arteries by multiple plaques within the arteries.
Collateral Circulation best shows why there was adequate and necessary blood flow to the brain.
In Collateral Circulation closed smaller arteries links and connect to two bigger arteries or certain points of the same artery acting as another way of blood supply.
Collateral vessels are often closed but in people with coronary heart disease or stroke, it will expand and increase.
Note: there is something called collateral Willis referring to the choice of it remain close in some people and being open in some people.
The up and down arrows you carved into the spinal cord are meant to represent the movement of different nerve signals. These signals, which are slso called action potential, are coordinated movements of sodium and potassium ions that are psocessed across the nerve cell membranes
