Bacteria with an optimum growth temperature of 37 degrees celsius are called mesophiles.
<h3>What are mesophiles? </h3>
These are a group of organisms that grow at moderate temperatures. Their optimum growth temperature ranges from 20 degrees Celsius to 40 degrees Celcius.
This term generally only applies to microorganisms, especially bacteria. There are other groups of bacteria which grow at relatively high or low temperatures
Thermophiles are bacteria that grow at a relatively high temperature and psychrophiles are bacteria that grow at relatively low temperatures.
The optimum temperatures of these bacteria are different because of the expression of certain alleles which release certain enzymes which are only active at particular temperatures.

Answer:
D. It formed from magma that cooled quickly
Explanation:
From several experiments, geologists have come to terms with the fact that when magma cools rapidly, it does not give room for large and big sized crystals to form. Instead, tiny, little crystals would be formed.
For example, obsidian and most volcanic rocks.
When a magma has enough time to cool and solidify, we see very big crystals of minerals in them.
