Answer:
a) another living cell
Explanation:
"All living cells arise from pre-existing cells by division."
A point mutation that does not result in a change to the amino acid coded for is said to be a synonymous mutation.
There is a change in the DNA sequence which codes for the amino acid in the sequence for protein but the amino acid that is being encoded does not change. Redundancy occurs in the genetic code which means multiple codons can code for the same amino acid but the change or the mutation occurs at the third position of the codon and the amino acid to be incorporated remains same at the particular position of the protein sequence.
<span>An effect of a decrease in the surface-area-to-volume ratio of a cell is Choice B. Waste removal becomes slower. Decrease in the surface area to volume ratio means that the cell is growing in size. This growth makes diffusion less efficient resulting to the center of the cell not receiving its required substances. The cell processes slows down and the cell must break down into smaller cells that has larger SA:V ratio to make diffusion more efficient. </span>
