The blood located in the heart’s left ventricle, which is rich in oxygen, travels through the aorta artery to the whole body, where the blood (coming from the arteries) gives oxygen and “food” to the capillaries and receives carbon dioxide and waste, which then (throughly the veins) travels back to the heart’s right atrium. Then, it goes from the heart’s right ventricle to the lungs, where it “gives” carbon dioxide and waste and receives oxygen, which then returns to the heart’s left atrium.

<span>The discoverers of DNA were not James
D Watson and Francis Crick. They are the first scientist to formulate an
accurate description of the DNA’s (deoxyribonucleic acid) complex ,
double-helical structure. They discovered that base pairing nucleotides must
be; adenine and thymine; and cytosine and guanine. These base pairs are held
together by a hydrogen bond, atype of chemical reaction that s easy to break
and easy to reform. The statement is “DNA
is a double helix made of two strands linked together with hydrogen
bonds.”</span>
The axons of the retina culminate in the optic nerve which forms a blind spot on the retina.
I hope this helps!
