The length of a vessel is directly proportional to its resistance: the longer the veessel, the greater the resistance and the lower the flow. As with blood volume, this makes intuitive sense, since the increased surface area of the vessel will impede the flow of blood.
I believe the correct answer is chromosome.
<h2>
Explanation:</h2>
We inherit 23 chromosomes from our mother and another 23 chromosome pairs from our father. You have to inherit a defective chromosome for you to get the mutation. This is what is called germ line mutation usually carried in the sperm or ovum. Of the 23 chromosomes, 22 are autosomal and 1 is chromosomal meaning of the 23 one of them is X and another one is . You get the Y from your father and the X from your mother.
A concentration gradient and membrane that allows water to pass, but not the solute, must be present
Potassium is 10 to 20 times higher inside the cell, and sodium is 10 to 20 times higher outside the cell. The potential difference across the cell is important in several processes such as transmission of nerve impulses and maintain the ion balance.
The sodium concentration higher out side and potassium higher inside the cell then it moves two potassium into the cell where potassium levels are high and pump three sodium ions out of the cell and into the extracellular fluid.
This is due to action of membrane active transport system which pumps sodium out of the cell and potassium into it. Both helps in body maintain flid and blood volume so it can function normally.

Answer:
Evolution is a scientific theory used by biologists. It explains how living things change over a long time, and how they have come to be the way they are. ... It is known that living things have changed over time, because their remains can be seen in the rocks. These remains are called 'fossils'.
