Answer:
0
Explanation:
This question involves two genes; A and B. According to the question, two parents are crossed as follows: AABB × Aabb. The parents will produce the following gametes:
AABB- AB, AB, AB, AB
Aabb - Ab, Ab, ab, ab
Using these gametes in a punnet square (see attached image), the offsprings in the following proportion will be produced:
AABb = 4/16 = 1/4
AaBb = 4/16 = 1/4
Therefore, none (0) of the offsprings will resemble the phenotype of the second parent (Aabb).

If the scientists are studying the effects of different temperatures on the processing speed of a computer chip then they would need to know the temperature inside the computer.
However, your questions doesn't include the full question text, so I cannot be sure what answer you need.
If the question is what do they need to know to do this, the answer is C.
If the question is how could they measure this when they subject the computer to different temperatures, then the answer is D.
Plants release nectar which attracts birds to come and eat. As the bird eats the plant pollen (plant sperm) will get on the bird, and travel with it to other plants were the pollen will falls off and impregnates another plants due to plants having both female, and male bodies thus causing cross-pollination. This happen thru natural selection because the plants has nectar and pollen due them wanting to be able to spread and have more offsprings.
