Answer: The mutation is substitution.
Explanation:
There are three main types of mutation:
Substitution, deletion, and insertion.
We would be able to tell right away if the second sequence had an insertion or deletion, because it would have a different number of letters than first sequence. However, it does not. Both sequences have 12 letters.
But, the 8th letter in the first sequence (T) is different from the 8th letter in the second sequence (A).
This is substitution.

on many US beaches
Explanation:
glaciers cause erosion in two main ways, plucking and abrasion. they freeze to the bottom of the glacier and they are carried away by the flowing ice. abrasion is the process in which a glacier scrapes underlining Rock. the segments and rock Frozen in the ice at the bottom and slides of a glacier act like sandpaper
The answer is; producing a unique antibody from all other B cells by genomic rearrangement.
An isolated B cell produces monoclonal antibodies (also called Immunoglobulins). Different B cell types produce different types of antibodies (hence the serum of an animal has polyclonal antibodies). Memory B cells are developed when a particular infection is eradicated by the immune system. These B cells proliferate when the infection returns by producing the same antibodies that were effective against the foreign entity.
The concept would be crystallization. As magma cools inside or outside of the earth it crystallizes into an igneous rock. Intrusive (formed inside crust) igneous rocks are typically more course grained and contain many different noticeable minerals (for example, granite). Extrusive (formed outside) igneous rocks are typically more porous and are more fine grained then intrusive rocks (example, obsidian).
