Answer:
i am fairly sure the last option isn't true.. i hope i'm correct
Answer:
1- dilate
2- perfusion
Explanation
when blood pressure increase the arterioles dilate (become smaller) so that cells can absorb the oxygen from the blood easily. perfusion will be altered or slowed down. (The perfusion is the passage of fluid through the circulatory system. )
Answer:
Option B, are proteins embedded in the cell walls that transport water
Explanation:
Aquaporins are water channels that are present in the membrane of root cell and belong to the group of major intrinsic protein (MIP) family. It not only assists in rapid Trans membrane water transport but also regulate the flux of water between cells and within the cell
They are small, hydrophobic, intrinsic membrane proteins that create water channels for movement of water into and between cells across all organ systems and hence they are known as plumbing system for cells and
Thus, option B is correct
The answer is D. A cold tundra
