e. all of the above

Accepted Answer

Hey, everyone. Let's take a look at this question together which of the following statements is true about viruses. Is it answer choice. A viruses are specific about their target cells. Answer choice B viruses can infect any animal vectors to reach their desired host. Answer choice C viruses hijack the hosts, stem cells to create copies of itself or answer choice D all of the above. Let's work this problem out together to try to figure out which of the following answer choices contains a statement about viruses. That is true. So in order to solve this question, we have to recall what we have learned about viruses to determine which of the following statements is true. So starting off with answer choice A which says that viruses are specific about their target cells. Well, we know that viruses can infect only certain species of hosts and only certain cells within that host, which means that viruses are specific about their target cells. So answer choice A is a true statement. Next, we have answer choice B which says that viruses can infect any animal vectors to reach their desired host. And we can recall that viruses require A species specific vector, which means that a virus cannot infect any animal vector to reach their desired host as they require species specific vectors, which makes answer choice B a false statement. So answer choice B cannot be the correct answer. And since we have at least one statement, that is false, answer choice D cannot be the correct answer either. And since we can only have one statement about viruses, that is true, that would make answer choice c incorrect. Since it must be a false statement, which we know answer choice C is a false statement as it says that viruses hijack the hosts stem cells to create copies of itself. And we note that it is not the host's stem cells that the virus hijacks in order to create copies of itself. And instead viruses target the host's mature cells. So answer choice C is indeed a false statement making answer choice. A the correct answer as it is the only answer choice which contains a statement about viruses. That is true.
