Answer:
RBCs' production is controlled by erythropoietin.
Mature RBCs are released into the bloodstream after approximately seven days RBCs are produced in the bone marrow
Explanation:
The hormone erythropoietin is produced and released in the bloodstream by peritubular interstitial cells of kidneys. The function of erythropoietin is to increase the number of the precursors of red blood cells and thereby to stimulate the production of red blood cells in the bone marrow. When the oxygen supply to body cells is reduced, the hormone erythropoietin stimulates the development of proerythroblasts into reticulocytes and thereby increases the RBC production.
RBCs are produced by the process of erythropoiesis and take about seven days to become mature and to be released in circulation to serve the function of oxygen delivery. The maturation of RBCs also includes the loss of most of the organelles such as the nucleus and mitochondria to accommodate hemoglobin protein. The life span of circulating RBCs is about 100-120 days.

Answer:
C) The cell membrane allows water to enter and leave the cell.
Explanation:
The cell membrane is a selectively permeable membrane that allows certain non-polar and small substances to move through it. Water is allowed to move freely through the cell membrane according to the concentration gradient. After the removal of shells, the membrane served as the outer most covering of eggs.
When placed in a different solution, the water moved in or out of the cells depending upon the concentration gradient. If the egg cells were placed in a hypotonic solution, water will enter into the egg cell resulting in the increase in its volume. On the other hand, when an egg cell is placed in a hypertonic solution, water leaves the cell through the cell membrane and the egg shrinks. This passive movement of water through the cell membrane is called osmosis.
