Answer:

132 million years ago

Explanation:

The two DNA mit have a difference of 4 bases. If the frequency of mutation is one every 33 million years. We can stipulate that the time that has passed since the two species diverged from a common ancestor is 132 million years. This can be calculated by multiplying the number of variations by the frequency.

4 (variations) x 33 million years = 132 million years.

Species A mt DNA :  TACAAGATAC

Species B mtDNA:    TACGCGTAAC

What major structure brings oxygen and nutrients to the cells and carries away waste?
liubo4ka [24]
<span>The major structure that supplies the cells with nutrients and removes their waste is the circulatory system. The circulatory system is composed of the heart, the blood vessels going from and back to the heart, and the blood that travels inside them. The blood vessels that carry nutrient and oxygen-rich blood to the cells are arteries. They become the thinner arterioles, and then the thinnest capillaries. With the exception of the pulmonary arteries, which carry non-oxygenated blood from the heart to the lungs, all arteries carry oxygenated blood. The capillaries disburse the nutrients and oxygen to the cells and pick up wastes and carbon dioxide, form into the thicker venules, then to form veins, which lead back to the heart (with the exception of the pulmonary veins, which carry oxygenated blood from the lungs to the heart). Veins also differ from arteries in that veins have valves to prevent blood from flowing backward.</span>
