Rosa drew a diagram to compare substitution mutations and insertion mutations. Which label belongs in the area marked "Y"?

may change the type of amino acid
decreases the number of bases in the sequence
never changes the type of amino acid
increases the number of bases in the sequence

Mutations are the changes produced in the nucleotide sequence of the genome.

There are four main types of mutations

Substitution

Insertion

Deletion

Duplication.

A small segment of chromosome mat be missing. This condition is known as deletion.

For example, Normal chromosome has A B C D E F G. If deletion mutation occurs then mutated chromosome has A D E F G and B C got deleted.

In this condition, a part of chromosome present in exec ess to the normal chromosome.

For example, Normal Chromosome has A B C D E F G. If duplication mutation occurs, then mutated chromosome had A B C B C D E F G and B C is duplicated.

Substitution is a type of mutation where one base pair is replaced by a different base pair.

For example, in the sequence CAAGT, if C replaces G, it is a substitution mutation.

In genetics, an insertion is the addition of one or more nucleotide base pairs into a DNA sequence.

For example, in the sequence CAAGT, if extra base G gets inserted after C, the new sequence would be CGAAGT.

Both substitution and insertion mutations change the position of nucleotide thus, the type of amino acid.

some of your causes might be acidic rain or natural wildfires that cause the parks to be degraded

hope this any more questions i am here plz mark brainliest

condensation. good luck!
