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:
- Half (8/16) of the offspring will have gray fur and black eyes.
- Half (8/16) of the offspring will have gray fur and red eyes.
- None (0/16) of the offspring will have white fur.
Explanation:
For the purposes of this question, we will assume the following notation for the involved alleles:
G: gray fur (dominant), g: white fur (recessive).
B: black eyes (dominant), b: red eyes (recessive).
A GGbb rabbit may only produce one type of gametes, namely Gb.
A ggBb rabbit may produce either gB or gb gametes.
Since not all theoretical combinations are present, the resulting Punnett square may be simplified as follows:
| Gb
——-+-————
gB | GgBb
——-+-————
gb | Ggbb
As seen above, 100% of the offspring will have a Gg genotype (resulting in gray fur). As for eye color, half of them will have a Bb genotype (resulting in black eyes) whereas the other half will have a bb genotype (red eyes).
Answer:
The internal combustion engine in the car converts the potential chemical energy in gasoline and oxygen into thermal energy which is transformed into the mechanical energy that accelerates the vehicle (increasing its kinetic energy) by causing the pressure and performing the work on the pistons.
