More information required

Explanation:

Is there a picture you forgot to post with the question?

In the problem you mention, which I assume comes from the study of finches in the Galapagos, some birds evolved to have different beaks, depending on the food available. Depending on what kind of seeds there are, different beak sizes were selected for, with those with the right fit eventually winning out over the rest on the individual islands.

Answer:

Lymphatic: bacteria invade the body but are removed with the help of cells

Endocrine: A chemical message is signaled to help the body relax and sleep

Nikitich [7]

Answer:

The six codons for arginine are the following:

GCA, GCG, GCT, GCC, TCT, TCC

A) Considering the individual bases in each codon, three mutations are possible at each base position. Hence, 3 × 3 × 6 = 54 mutations are possible.

B) Considering the mutations at the 3rd base: 3 × 4 + 1 × 2 = 14 of these mutations are silent mutations.

C) Lysine codons are the following:

TTT, TTC

There are two possible mutations that can give a lys codon.

Hope that answers the question, have a great day!
