The right answer is spongy bone (cancellous bone).

In otosclerosis, the new bone blocks the movement of the stirrup, causing transmission hypoacusia. Otosclerosis can also cause perceptive deafness, especially when otosclerotic bone foci are close to scala media. Half of all cases are hereditary. The measles virus may play a role in triggering a genetic predisposition to otosclerosis.

nekit [7.7K]

Answer:

The answer is E.

Explanation:

In vivo or in vitro evolution (Directed Evolution) is a technique used by genetic scientists to push the change in nucleic acids or proteins in a specific direction to get the end results that they want.

And high-fidelity polymerase is used to get a replica of the target DNA that has less errors.

So the situation given in the question where researchers use a higher-fidelity DNA polymerase in vitro evolution, the mutation rate would most likely be lower because of the high-fidelity DNA polymerase.

I hope this answer helps.

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.
