Answer:
Directional selection
Explanation:
The type of natural selection that favors one of the extreme phenotypes due to its higher survival and reproductive success is known as directional selection. It shifts the peak of the distribution curve of the phenotype towards one extreme end.
In the given example, the plants with thickest leaves have better survival and reproductive success under the drier climate of their new habitat. This would allow the plants with thickest leaves to survive well and leave more progeny.
After several generations, the population would exhibit an increased frequency of plants with thickest leaves over the plants with intermediate and thinnest leaves.
Since the natural selection has favored one extreme phenotype (thickest leaves) over the average (intermediate thickness) and the other extreme (thinnest leaves) phenotype, it is directional selection.
It grows close together to form the body's "skin".
Options: A. contralateral
B. ipsilateral
C. both
Answer:B. ipsilateral
Explanation:The ciliospinal reflex which is also known bas pupillary-skin reflex is usually made uo of the dilation of the ipsilateral pupil this dilation is in response to pain applied to the neck, face, and upper trunk.
If you stimulate the left side of the subject, the response will be only in the ipsilateral which means the stimulation will be felt in the same side of the subject which in this case is the Left side if the subject.
