Answer:
Option A
Explanation:
Sperm undergo more mitotic cellular divisions than egg and therefore have a higher risk of developing a spontaneous mutation.
As noted from the explanation given above...in the process of development in males, the sperm cells always undergo many mitotic cellular division throughout their life increasimg the males' chances of undergoing spontaneous mutations as compared to the females during development where it gets to a certain point in their lives where they stop producing egg cells after the once division.
Thus, the continuous divisions undergone by the sperm cells acquire more spontaneous mutations on the cell that produces this lycantrophy trait.

By placing the pots with detergent in the sun and the pots
without detergent in the shade, the student is not comparing the effects that
detergent has in the growing rate of the seeds under the same conditions;
besides, he does not have a control group. Therefore, he will not be able to
determine if the growing rate of the plants were affected by the detergent, the
lack of sunlight, or a combination of both factors.
Answer: Plant vegetation so that their roots hold the soil firmly.
Build walls around the farm area.
Add natural fertilizers to the soil.
Soil erosion is a process of removal of top layer of soil which get sediment at some other place due to the affect of agents like wind and water. The superficial upper layers of soil are rich source of nutrients and organic matter and active region for germination of seeds and plant growth. Soil erosion removes these superficial layers making soil less fertile or not fertile and less useful for plant growth.
Plants growing in a vegetation have roots which can hold the soil and will prevent soil erosion from wind and water or any other agent. Building of walls around the farm area will prevent flood water to get inside the farm area and hence, prevents soil erosion by water. Addition of natural fertilizers to the soil adds up nutrients to the soil which facilitate plant growth and plant roots hold the soil therefore, prevents soil erosion.

<u>Binary Fission. </u>
- <em><u>Binary division is a process of cell division in which an organism replicates itself together with its DNA, then divides into two identical organisms.</u></em>
- <em><u>Binary fusion is a type of asexual reproduction by separation of the body of n organism into two bodies</u></em>. Organism duplicates its genetic material also known as the DNA, and then divides into two parts, with each new organism receiving a copy of DNA.
