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.

Break away the sand mold and remove the casting.
Explanation:

When the wind hits an outcrop of rock the sand it is carrying is blasted against it. Over time it would form to become that funky mushroom shape.
hope this helped! :))
