How does a viral immunization prevent disease? a. the altered virus remains in the body and outcompetes the natural version if the virus returns. b. memory cells that develop in response to the weakened virus will respond more quickly if the virus returns. c. the nonspecific immune response will prevent the virus from entering the body. d. the altered virus remains in the body and recognizes itself if the virus returns.

When you go through viral immunization, this virus is injected into the body.

When the virus enters the body, the body's immune system recognizes this virus, and memory cells are developed to this specific virus.

These memory cells develop because the body wants to protect itself from any other invasion of this virus in the future. So the memory cells will then respond rapidly if this virus shows up again in the future.

Therefore, the answer is: B) Memory cells that develop in response to the weakened virus will respond more quickly if the virus returns.

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
