Answer:
c. Directional selection
Explanation:
Directional selection is a type of natural selection that occurs when selective pressure favors one extreme phenotype over any other phenotype existing in a population. Only one extreme phenotype is favored over time.
A good example of directional selection is the natural selection that occurs in giraffes, where alleles for long necks were favored against alleles for short necks as a result of selection pressure among the different phenotypes. Over time, giraffes having long necks dominated the population as the distribution of length of neck shifts towards the phenotype for long necks.
The four sensations detected by the tactile receptors in the skin are touch, pressure and vibration and tickle.
<h3>What are the 4 sensations that the receptors found in the skin have?</h3>
They are nerve endings formed by a branched axon. They are distributed in almost all parts of the body and capture mechanical (pressure), thermal (cold and heat) and especially painful sensations.
This is because Tactile sensations are the ones that detect touch, pressure, and vibration. About six different types of tactile receptors are known.

The shape of a stream channel is usually flowing you could say. They constantly adjust to changes in stream flow
The channel is affected by the movement of rock material. The stream flows down a slope along a defined path. Streams may vary in width from centimeters to kilometers
I hope this helps somewhat
