The correct order that oxygen enters the body is definitely C.
Bronchi, then Lungs, bronchioles, alveoli, blood!
Good luck!!

Answer:
Vitamin C
Explanation:
Vitamin C is known as the ascorbic acid performs various functions in humans and is present as the constituent of the skin epidermis.
Vitamin C protects the skin from photodamage caused by the harmful UV radiations and helps in the synthesis of collagen, a type of connective tissue in the human body.
Vitamin C is involved in the hydroxylation of collagen synthesis which is important for the support of the epidermis and extracellular stability.
The deficiency of Vitamin C causes scurvy characterized y the fragility of blood vessels and bleeding.
Thus, Vitamin C is the correct answer.
Answer:
It decreases the levels of cAMP in the cell, repressing transcription from the lac operon.
Explanation:
When glucose is absent, cAMP serves as coactivator binds to CRP, the catabolite gene activator protein. The CRP-cAMP complex binds to the site near the lac promoter and stimulates the expression of the operon by RNA polymerase many folds.
Catabolite repression refers to inhibition of the synthesis of enzymes of lactose catabolism when glucose is present as an energy source. In the presence of glucose, synthesis of cAMP is inhibited resulting in its lower cellular concentration. The lower cAMP levels do not allow the binding of cAMP and CRP. The result is reduced expressed of lac operon.
Answer: I believe the answer is A
Explanation:
When plants undergo photosynthesis, they make sugar. Why sugar? Because, it is one of their resources they need to survive. I know that they also need oxygen and water. Carbon dioxide is also vital in their survival. I hope this helps!
