Nerves that detect deep pressure are called Pacinian corpuscles.
Pacinian corpuscles are microscopic onion-shaped nerve structures that are situated in the dermis and hypodermis. Pacinian corpuscles detect deep pressure and vibration. This nerve has a myelinated nerve ending in the middle of its structure and the external layer contains flattened cells, a lymph-like fluid and collagen fibers. The structure of pacinian corpuscles provides a fast response and rapid recovery by transmitting fast events. This make them sensitive to pressure and vibration.
D - The organisms on the island are slightly different than those on the mainland.
The reason why this is the correct answer is because each successive generation on the mainland as well as the island both develop and continue adapting to their specific ecological niche and environment. They are, howerer, both still part of the same species.

- The atmosphere of both the planets comprises of the gases, hydrogen, helium and methane.

Answer:
The correct answer is - principle of segregation.
Explanation:
The principle of segregation explains that the in what manner pair of gene type or alleles are separated into sex or reproductive cells. These variants are known as the gene alleles. These are first studied by the Mendel as the traits in 1865. In this case the results are not consistent with this principle of segregation concept.
Thus, the correct answer is - principle of segregation.
