The right answer is A: intercellular communication.
An example of intercellular communication is the one between the kidney, liver and lungs to preserve water-soluble homeostasis.
Angiotensinogen, an inactive protein produced by the liver, circulates in the blood. It is the precursor of the active peptides angiotensin I and II, and the only substrate of renin.
In the event of a drop in the pressure in the renal artery, renin (an enzyme sometimes considered as a hormone) is secreted in the kidney by differentiated myoepithelial cells of the arteriole afferent of the juxtaglomerular apparatus. There are also other stimuli promoting renin secretion: decreased natremia in the distal convoluted tubule, ß-agonists, hyperkalemia, PGI2 and stimulation of juxta-glomerular cells by the sympathetic nervous system)
The angiotensinogen is cleaved by the renin and forms a decapeptide called "angiotensin I", inactive.
Angiotensin I will then be converted primarily to angiotensin II by a carboxypeptidase, the angiotensin converting enzyme. This enzyme, secreted by the liver, acts at the pulmonary level.
Answer;
The offsprings will be such that , a normal vision female, a heterozygous female, normal male and a colorblind male.
Explanation;
-Most X-linked traits in humans are recessive. One example of an X-linked trait is red-green colorblindness. Let (Xc) represent the recessive allele that causes colorblindness and (XC) represent the normal dominant allele. Females that are XCXC or XCXc have normal color vision, while XcXc females are colorblind. For males with; XcY are color blind, while those with XCY are have normal color vision.
Heterozygous female, XcXC
Normal male, XCY
The offspring of the parents, XcXC x XCY, are: XcXC (heterozygous female), XCXC( normal vision female), XCY (normal vision male), XcY (color blind male).
