Hiv's genome of rna includes the code for reverse transcriptase (rt), an enzyme that acts early in infection to synthesize a dna genome off of an rna template. the hiv genome also codes for protease (pr), an enzyme that acts later in infection by cutting long viral polyproteins into smaller, functional proteins. both rt and pr represent potential targets for antiretroviral drugs. drugs called nucleoside analogs (na) act against rt, whereas drugs called protease inhibitors (pi) act against pr. which of the following treatment options would most likely avoid the evolution of drug-resistant hiv (assuming no drug interactions or side effects)?

(a) use a series of nas, one at a time, and change about once a week.

(b) use a single pi, but slowly increase the dosage over the course of a week.

(c) use high doses of na and a pi at the same time for a period not to exceed one day.

(d) use moderate doses of na and two different pis at the same time for several months.

In general, how long does it take to accomplish a long-term goal? a.a few days to a weekb.a few weeks to a monthc.a few months to a yeard. more than a year

You decide that the introduction should also discuss the extremophiles that are referred to as the archaea. these single-cell organisms are considered "extremophiles" due to their ability to survive and reproduce in environmental conditions that would be hostile for most living organisms. archaea species have been isolated from highly acidic sulfur springs, ocean floor thermal vents with temperatures that exceed boiling, and subarctic ice well below freezing. while still considered to be prokaryotic, the archaea have numerous differences that place them apart from the bacteria. choose the characteristics that separate the archaea from other prokaryotic cells. select all that apply. view available hint(s) select all that apply. archaea lack true peptidoglycan in their cell walls. the morphology of the cell is rigid and is geometric in shape, similar to a sphere or cylinder. the cytoplasmic membrane lipids of archaea have branched or ringform hydrocarbon chains. all currently identified and characterized archaea have been linked as the causative agent to an animal or human disease.

Pls in your opinion, what are the limiting factors that might affect the growth or diversity of our ecosystem? respond to this question in claim, evidence, reasoning format. 1. make your claim (i are the limiting factors that might affect the growth or diversity of our 2. follow the claim with 3 pieces of evidence. evidence may be taken from the reading, the videos, previous lessons, or googled answers. site sources, too. 3. use reasoning to explain why you chose your evidence.
