Exoskeleton

Exoskeleton is a evolutionary innovation. This is operated by muscles attached to it and acts as an armor. Other than support this is an adaptive mechanism to provide protection against predators. In vertebrates, it is considered as the dermal bone that developed via membranous ossification. Fishes retained their exoskeleton in the form of their scales. However, in some organisms terrestrial evolution allows the loss of exoskeleton and formed a more mobile endoskeleton,

ANEK [815]

Answer:

c. The P allele is less frequent in the US than the p allele.

Explanation:

If people with the heterozygous genotype "Pp" present polydactyly, only people with the genotype "pp" will not present polydactyly. Since 99.9% of the population do not exhibit polydactyly, then it can be concluded that the "p" allele is much more frequent in the US than the "P" allele.

Therefore, the answer is:

c. The P allele is less frequent in the US than the p allele.

Arturiano [62]

Granite is a type of intrusive igneous rock

Explanation:

An igneous rock formed from hot magma or lava cools, solidifies or crystallizes to form rocks.

Based on the rate of cooling of magma, igneous rocks can either be intrusive or extrusive.  

A slow cooling of the magma deep within the earth without reaching the surface of the volcano leads to the production of intrusive igneous rocks.

This slow cooling leads to crystallization forming large crystals visible to the eyes with a phaneritic texture.

Granite has the best phaneritic texture among intrusive igneous rocks. Granite crystals can be easily visualized and are constituted by minerals like white feldspar, black hornblende, translucent quartz, and platy black biotite.

Extrusive igneous rocks like basalt are formed from microscopic crystals from fast cooling of magma.
