<h3><u>Answer and explanation;</u></h3>
- This can be done by<u> DNA sequencing which is the process of determining the accurate order of nucleotides within a DNA molecule</u>.
- By doing a DNA sequencing for the two sequences of DNA from the two species it will help compare the number of random mutations which have occurred in a molecular clock in the two species - that is, seeing how different the sequences are.
- This will make it possible to infer how long ago the species diverged.
Species A: GTTGAGCTAGTATGGACC
Species B: GATAAGCTAGTAAGGTCA
These species differ in 5 nucleotides.
This number should be multiplied by the rate of mutations; that is;
5 × 15 million years =75 million years.
Cytokinesis
-it’s the physical process of cell division

The plants and coral reefs are the organisms that produce the most oxygen released into the atmosphere.
