Answer:
The given case is an illustration of the disruptive selection phenomenon, which is one of the components of natural selection. In the process, both the extreme homozygotes are preferred or are considered more standard in comparison to the middle heterozygote.
The disruptive selection is also called diversifying selection, and in this form of selection, the extreme values for a specific trait are considered over the transitional values. In this kind of selection, the graph obtained would be demonstrating the bell curve that exhibits two peaks.
<span>The event that occurs first is cleavage. This occurs when the zygote (cell that is fertilized) divides itself and creates morula, which is a grouping of cells. Essentially, cleavage is the fertilization and division of the cell.</span>
Answer: Kira has difficulty in walking in smooth coordinated manner because she has suffered injury to the cerebellum.
Explanation:
Cerebellum is a part of the brain situated inferior to cerbrum and posterior to pons. It receives sensory information and converts it into motor responses. Motor coordination is when subsequent parts of the same movement, or the movements of several limbs or body parts are combined in a manner that is well timed, smooth, and efficient. Cerebellum coordinates voluntary motor movements resulting in smooth coordinated muscular activities. Injury to cerebellum causes its loss of function which in return causes
1) loss of coordinated movements
2) inability to perform alternate rapid movements
3) movement tremors
4) staggering wide based gait
Radioactive decay is used.
