3 point testcrosses focus on analyzing the inheritance blueprints of alleles by crossing triple heterozygotes with triple recessive homozygotes, allowing therefore to find out the distance between the alleles, and also their location order on the chromosome.
And it all comes down to the frequency of recombination, in this case such frequency between C&A is 0.02, in the same fashion that it's 0.08 between A&B; thereby the answer is A). 2
Explanation:
Natural selection is the mechanism that is responsible for the evolution of organisms.
In the given case, the Freshwater shrimp has been introduced to a pond in which the two species with variations are introduced.
The C. cantonensis is brighter in color whereas the C. multidentata is mottled drab in color. The predator fish can feed easily on the species which is brighter therefore C. cantonensis is more susceptible. The mottled drab species is not easily predated by the species.
The 30 % offsprings of C. cantonensis can survive till the reproductive age whereas 75% of C. multidentata. This shows that natural selection has acted on the color of the shrimp species selected against the predator fish species.
The species with mottled drab color is the result of the differential reproductive rate.
Natural selection is favoring the Caridina multidentata species due to its mottled coloration providing protection against predators, and acting against the Caridina cantonensis species due to its conspicuous coloring. Higher survival rates to reproductive age in Caridina multidentata suggest that, over time, this species will increase in population assuming other environmental factors remain constant.
In the given scenario, natural selection is favoring the Caridina multidentata species. The mottled and drab coloration is providing higher survival rates by offering protection against predation. On the other hand, natural selection is acting against the Caridina cantonensis species which has bright colors that make it easily detectable by predators, leading to its lower survival rates.
The given conditions of coloration and survival rates to reproductive age influence natural selection. The higher survival to reproductive age in Caridina multidentata ensures the transmission of its color characteristics to a larger number of offspring. This leads to the prediction that over time, the population of Caridina multidentata will tend to increase compared to Caridina cantonensis, assuming all other environmental factors remain constant.

II. A well-hydrated person is likely to have higher blood levels of angiotensin II than a dehydrated person.
III. Angiotensin II helps to slow the rate at which urine is produced.
IV. A class of drugs known as ACE inhibitors promote (enhance) the formation of angiotensin II.
Answer:
I. Angiotensin II is a hormone that is secreted by the kidneys.
Explanation:
The angiotensin II is a vasoconstrictor molecule secreted by the kidney. This hormone is known to be involved in the regulation of blood pressure and has effects on water and sodium intake.
Angiotensin II plays roles in the immune response and in the regulation of inflammatory response pathways
