Answer:

80 mm Hg

Explanation:

Immediately prior to ventricular systole, pressure in the aorta is about 80 mm Hg. This can be explained by the Frank-Starling Law which states that the stroke volume of the left ventricle will increase as the left ventricular volume increases due to the myocyte stretch which tends to cause a more forceful systolic contraction. This applies in the case that all of the other factors remain the same during that time.

ANTONII [103]

Answer:

D. It can function independently

Explanation:

A. Not a haploid, the daughter cell is going to be a diploid cell, because it is a body cell, not a sex cell; they are suppose to have the same amount of chromosomes as the parent cells.

B. It will go through cytokineses ( last step of the mitosis) the cells will not be connected to parent cell and is independent (D)

C. Inside the chromosomes, no matter it is a haploid or diploid cell, it will contain DNA.

D. After going through the cell cycle, the new daughter cell produced will be a new individual and do not connect to other cells.
