In gametogenesis , germinal cells multiply by mitosis and mature garnetes are formed by meiosis.
Answer:
A frameshift changes every codon past it. A base substitution only changes one codon.
Explanation:
DNA is comprised of nucleotides (A, C, T, G) that make up amino acids. Every three bases is called a codon and represents an amino acid.
In a frameshift mutation, a nucleotide is either added or deleted from the sequence. This offsets the entire sequence after it because the reading frame shifts. Here's an example:
ACTGCTATCGTCATC
If another T is added in between the first and second codons, then every codon after will be changed.
ACT>T<GCTATCGTCATC
A substitution mutation is usually less severe, as it only alters one codon in the sequence. These occur when one nucleotide is replaced by another one. Here's an example:
ACTGCTATCGTCATC
Let's say the first G is replaced by a T.
ACT>T<CTATCGTCATC
As you can see, none of the other codons changed.
Typically, a frameshift mutation is considered worse than a substitution mutation.

Answer:
C. The universe coalesced into one solar system after the Big Bang.
Explanation:
This is true because, since she is writing about Big Bang theory, she would have to include how the universe was able to expand to one solar system made up of different planetary bodies. This explanation would help someone reading her writeup to understand what the Big Bang theory is all about.
