Answer:
Density is a physical property of matter, as each element and compound has a unique density associated with it. Density defined in a qualitative manner as the measure of the relative "heaviness" of objects with a constant volume.
Answer:
A point mutation in the 1st base of a codon
Explanation:
A point mutations are mutations of one base in the DNA sequence. The effects of point mutations might be harmful, beneficial or neutral.
Deletion mutations are frameshift mutation, because they change the reading frame and thus affect the sequence of amino acids produced. Usually, protein changes its structure and function and become useless.
Point mutations at 2nd base of codon are misssense mutations, meaning that the new amino acid is produced, but it can be amino acid with similar properties. That will not affect the function of the protein a lot.
3rd base of a codon are often silent mutations, which means that the sam amino acid is produced (multiple codons can code for the same amino acid).
