Microtubules originate on the centre of the cell taking the positive end to the periphery of the cell, while the negative end remains turned to the centre of the cell. The melanosomes move along these microtubules using motor proteins desiganted kinesins and dyneins. The kinesins are responsible for moving the melanosomes to the positive end of the microtubule (periphery of the cell) generating dark-colored cells, whereas dyneins move the melanosomes to the negative end of the microtubule (centre of the cell) generating light-colored cells.

Explanation:
Type of homeostatic mechanism in the human body which is most common is the maintenance of body fluids, dilute and solutions of water that carry liquefied chemicals found in internal part of the cell and the surroundings of them. the internal part of the cells, it is named as intracellular fluid, the external part of the cells, it is named as extracellular fluid. All the materials such as oxygen, nutrients, proteins, and ions, are needed for survival.
Answer: Decrease
It will decrees because required volume of blood will not be emptied into the pulmonary circulation to reach the lung for oxygenation. Rather blood flows back into the Right atrium ,(regurgitation,) through the these valves during ventricular contraction ( systole)of the Right Ventricle instead to the pulmonary circulation which reduces blood flow leading to volume overload in the heart. Eventually this affects systemic circulation,
