Explanation:
"n" stands for haploid number and has 23 chromosomes, which is half the diploid number, represented as 2n and having 46 chromosomes .
The type of lipid formed from rings of carbon atoms which regulate sexual function, blood glucose levels and are an important component in <u>cell membranes</u> are known as Steroids.
Steroids- A steroid is an organic molecule having four rings organized in a certain chemical configuration that is physiologically active. The two main biological roles of steroids are as signaling molecules and as critical elements of cell membranes that affect membrane fluidity.
Cell Membrane- All cells have a cell membrane, also known as a plasma membrane, which divides the inside of the cell from the external environment. The movement of materials into and out of the cell is controlled by the cell membrane.

<span>The blood flows through hepatic portal vein traveling to the liver, then makes it another artery which is posterior vena cava making it to the heart. It makes itself afterward to the pulmonary artery where it reaches the lungs, going back to the heart via the pulmonary vein. Eventually, it goes to the kidney through different parts such as the aortic arch, dorsal aorta and the renal artery.</span>
SYSTOLE
The contraction of ventricles is called systole. Each period of systole is followed by diastole when the heart is at rest. The ejection fraction is the measure of cardiac output every systole. Systole corresponds to the phase 0 which is the point of stimulation. The membrane at this point is depolarized which means that there is no net charge. This time cell cannot contract. During repolarization, sodium goes back the cell and muscles is now ready for another contraction.
