B- Lipids
C-Carbohydrates
D- Nucleic Acids

D- Nucleic Acids

Explanation:

Blood clotting is a process whereby a person's blood coagulates due to the formation of a white fibrous protein substance called FIBRIN. The essence of blood clotting is to prevent excessive flow/waste of blood when a blood vessel is wounded.

However, certain substances are needed for this process of blood clotting to occur in our body. Some individuals lack this substances and hence bleed continuously during injury, a condition known as HEMORRHAGE. The substances such as FIBRIN, a protein needed for blood clotting is encoded by GENES which makes up DNA (a type of nucleic acid).

Therefore, NUCLEIC ACID biomolecules determines a person's ability to clot blood properly because nucleic acids make up DNA, which contains segments (genes) that encode the synthesis of proteins (fibrin) needed for blood clotting to occur. Hence, it all boils down to NUCLEIC ACIDS.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
