Question
21. The development of HAART, highly active antiretroviral therapy is a more offective treatment for HIV because it is a A. Single drug that is more powerful than those previously used B. Single drug that targets multiple stages in the viral replicative cycle C. Combination of drugs that target different stages in the viral replicative cycle D. Combination of drugs that target the same stage in the viral replicative eyele 22. Why are fungal infections hard to treat? A. Very difficult to diagnose B. Bad side effects for most drugs used to treat them C. Fungi are eukaryotes so what hurts them typically harms human cells D. Not enough mycological physicians currently practicing E. Both B and C are correct 23. In animals, such as grasshoppers, the young resemble the adults during development A. Juvenile development B. Degenerate aging C. Partial maturation D. Incomplete metamorphosis E. Haplodiploidy 24. An electron microscope technician took multiple images of viruses for two different research labs. Unfortunately, he forgot to label the samples and now they are mixed up. One lab studies viruses that attack bacteria, and the other lab studies viruses that attack humans. How can he sort the viruses? A. The larger virions are human pathogens and the smaller virions are bacterial pathogens B. The more complex virions are human pathogens and the less complex virions are bacterial pathogens C The less complex virions are human pathogens and the more complex virions are bacterial pathogens. D. He cannot- viral structural complexity and size does not correlate with the complexity of the organism 25. Currently, the largest known organism on Earth is A. Blue whale B. Colossal squid C. Honey mushroom D. Giant sequoia E. African bush elephantExplanation / Answer
21. The answer is C) Combination of drugs that target different stages in the viral replicative cycle.
HAART therapy uses a cocktail of drugs (combination of 3 or more drugs), each of them targets a different step of the viral infection.
22. The answer is E) Both B and C are correct.
Fungal infections are hard to treat because fungi is closely related. So if we use any drugs to kill them there's a chance that our own cells may get damaged. That's why most of the drugs are unsafe and henceforth have side effects.
23. The answer is D) Incomplete Metamorphosis.
In this the youngs which are called nymphs looks like an adult except for their small size as compared to adults.
25. The answer is C) Honey Mushroom.
It is the largest known organism on earth also known as Armillaria or honey fungus.
