Answer:
The active smokers and those getting exposed, that is, passive smokers are at enhanced threat of bacterial infections. Getting exposed to tobacco smoke enhances vulnerability to respiratory tract infections, comprising pneumonia, tuberculosis, and Legionnaires disease.
Smoking compromises the anti-bacterial activities of leukocytes incorporating monocytes, neutrophils, B cells, and T cells, thus, demonstrating the mechanism for enhanced risk of infections.
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.
"B" is not correct.
We know that veins carry blood to the heart, lungs exhale carbon dioxide.
"A" is the correct answer.

They will likely be wiped out as well, since if the fungus can wipe out some of the Cavendish bananas, they will be likely to be able to wipe out the rest since they all share the same genes. Since they all share the same genes they will have the same weaknesses the fungus can exploit
Ost proteins that function in the cytosol (such as actin) or in the nucleus (such as DNA polymerase) are synthesized by free ribosomes. Proteins that function within the endomembrane system (such as lysosomal enzymes) or those that are destined for secretion from the cell (such as insulin) are synthesized by bound ribosomes.
<span>As a protein destined for the endomembrane system is being synthesized by a ribosome, the first amino acids in the growing polypeptide chain act as a signal sequence. That signal sequence ensures that the ribosome binds to the outer membrane of the ER and that the protein enters the ER lumen.</span>
