Answer:
25% heterozygous tall
Explanation:
If we take the F1 generation as parents and let them self-fertilise, we have 4 crosses.
The first one for homozygous tall, then we have 100% AA.
The second and third one for heterozygous tall and we have 25% AA, 50%Aa and 25%aa for each of them.
The last one would be for dwarf, and we'll have 100%aa.
Adding all of them, we'll have
AA = 100 + 25 + 25 = 150%
Aa = 50+50 = 100%
aa = 100 + 25 + 25 = 150%
as we had 4 crosses, so dividing the total percentages by 4, we'll have,
AA = 37.5%
Aa = 25%
aa = 37.5%
:. The percentage of heterozygous tall would be 25%.
Hope it helps:)
Answer:
Overpopulation in the area's main source of prey, such as rabbits, mice, etc.
Explanation:
A hawk is a predatory creature. That means that it feeds off of prey, such as mice or rabbits. In the case that the population saw a sudden decrease, the population sizes of the hawk's main source of prey would increase due to hving less of a threat towards their own survival.
Given what we know about nutrition, we can confirm that the runner's meal would have to contain 30 grams of protein.
The runner in question wishes to complete a two-hour run while expending 4kcal or calories <u><em>per minute</em></u>, for a total of 480kcal. Furthermore, the runner wishes for only 25% (120kcal) of this energy to come from a source of protein.
Since <em><u>every gram of </u></em><em><u>protein </u></em><em><u>adds </u></em><em><u>4 calories </u></em><em><u>of energy to the meal</u></em>, and we have to account for 120 calories, the runner will have to consume 30 grams of protein to achieve the desired results.
