Answer:
d. recessive epistasis
Explanation:
Recessive epistasis is a genetic phenomenon where the recessive gene is able to repress the expression of the dominant gene, presenting a greater number of individuals with the recessive genotype, in the F2 generation, than the number of individuals of the dominant genotype.
An example of this can be seen in the question above, where the F2 generation contained 178 purple, 60 red and 80 white flowers. The white color represents the recessive allele, while the red color presents the dominant allele. The recessive allele was expressed in greater quantity indicating the occurrence of recessive epistasis.

Answer:
homeostasis.
Explanation:
Homeostasis is the process whereby living systems maintain a stable internal environment despite changes in environmental conditions. Plants, like every other living organisms also perform this process to keep their internal environment in a stable state.
According to the question, some plants were exposed to ammonium nitrate, which serves as a nutrient, and 16 hours of sunlight needed for photosynthesis to take place. The plants exposed to ammonium nitrate and 16 hours sunlight grew taller because they had access to nutrients needed to bring about the process of photosynthesis, which provides the plant with energy source (Glucose).
The uptake of nutrients like ammonium nitrate by the plants is done in order to maintain a homeostatic internal environment. Without nutrients, which is the purpose of the ammonium nitrate, plants cannot grow. Hence, the plants exposed to ammonium nitrate, take it in to keep their internal environment functioning.
A good conclusion in a research paper restates the hypothesis so that reader can see the value of argument which either defends or criticizes the hypothesis. If it's a long paper it's a good idea to restate the hypothesis in the conclusion. This reminds the user of the hypothesis and draws the paper together. It also revisits the hypothesis and can provide new insight into the hypothesis. Another reason for restating the hypothesis in the conclusion is to pose questions and open the door for future research.
