Answer:

respiratory system fills the blood with oxygen and gets rid of the carbon dioxide while the cardiovascular system umps the oxygen rich blood all over the body (short answer)

Explanation:

the respiratory system aids in the supply of oxygen to the blood and the exit of carbon dioxide. when the heart takes in blood that is short of oxygen and full of carbon dioxide, the pulmonary arteries pumps the blood to the lungs, who then fill the low oxygen blood with oxygen and transport the carbon dioxide out of the lungs. this oxygen rich blood, which now has a rich amount of hemoglobin, is transported to the heart which is pumped or circulated it to the entire body. (long answer)

hope this helps !!

If flies that are heterozygous for all three traits are crossed;

we have HtHtHt × HtHtHt

Then the selected trihybrid traits for the cross will be (HHH,HHt, HtH, Htt, tHH, tHt, ttH, ttt)

We will realize that from the punnet square in the diagram below, the proportion of the offspring would you expect to be heterozygous for all three traits (i.e HtHtHt) is asterisk in the punnet square and will be \frac{8}{64}

= \frac{1}{8}
