Answer:
mutation rates can be used to design molecular clocks in order to estimate divergence times among species
Explanation:
In evolutionary biology, the substitution rates (also known as mutation rates) are used for the development of 'molecular clocks' which allow estimating the divergence times among species or among taxonomic groups. Molecular clocks can be designed by estimating the divergence rate of nucleotide sequences (either DNA or RNA) and amino acid (protein) sequences. These substitution rates can also be used to track how quickly viruses evolve (for example, in a pandemic situation).
Answer:
The cell wall present in fungi and bacteria permits these cells to withstand very dilute external medium without bursting.
Explanation:
A cell is <span>the smallest structural and functional unit of an organism. It effects the body by making and strengthening tissue, fighting unwanted cells, and by giving off oxygen throughout the body.</span>
Yes it is because sedimentary rock is lots of rocks condensed into 1
