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%.

Answer:
Information processing.
Explanation:
Brain is one of the most important organ of the body that maintains the coordination and control with the other system of body. The information processing occurs in the brain.
Information processing allows the brain to interpret the information so brain can employ the problem solving skill, critical thinking and decision making. This information processing also reduces the risk driving practice in highway transportation system.
Thus, the answer is information processing.
The ways the carbon in animal waste reach the atmosphere is : B. Decomposition, Fossil fuel formation, and fossil fuel emissions
