We do not use carbon dioxide to fuel our blood cells. It is a waste.
Arteries move blood from the heart to the rest of the body.
Veins carry the blood to the heart to be oxidized.
"D" is not correct.

We know that veins carry blood to the heart, lungs exhale carbon dioxide.
"A" is the correct answer.
I hope this helps!

Answer:
Hello your question is incomplete attached below is the complete question
answer : = 1.25
Explanation:
i) Determine the rate of mtDNA percent divergence
From the data given the most closely related specie is Chimpanzee ( 8.8 sequence difference )
Note : Given that this divergence took place seven million years from now
∴The rate of mtDNA percent divergence per 1 millions years
= 8.8 / 7 = 1.25
