Answer:
c) Nucleoside reverse transcriptase inhibitors may interfere with DNA replication by the host, not just by the virus.
Explanation:
A drug that targets the structures or processes specific to the pathogen or microbe has fewer side effects than the drugs that target the more general structures and processes exhibited by both the pathogen and host cells.
According to the given information, the nucleoside reverse transcriptase inhibitors resemble thymine and terminate the process of DNA replication. Thymine base is also one of the nitrogenous bases present in the human cells and other organisms. Therefore, the nucleoside reverse transcriptase inhibitors would terminate the process of DNA replication in both the virus and the host organism.
On the other hand, the non-nucleoside reverse transcriptase inhibitors specifically target the reverse transcriptase enzyme that is not present in host organisms. Therefore, the non-nucleoside reverse transcriptase inhibitors have fewer side effects than the nucleoside reverse transcriptase inhibitors.
Selectively permeable means that cells only allow certain molecules to enter or exit a cell.
In many cases, the activity of an enzyme is regulated by Negative feedback where the end product acts as a non competitive inhibitor.
In feedback inhibition the end product of a metabolic pathway acts on the key enzyme regulating entry to that pathway, keeping more of the end product from being produced. The feedback inhibition acts at the first committed step of the pathway, meaning the first step that's effectively irreversible. The pathway steps regulated by feedback inhibition are often catalyzed by allosteric enzymes.

While it may seem daunting, a basic meringue is nothing more than a mixture of beaten egg whites and sugar.
Answer:
D. service
Explanation:
Most people in the US work in jobs that require providing a service to others, whether it's at a restaurant, a department store, a school, etc. Yet, those who work in specialised jobs like agriculture, fishing, and mining are more rare because they need to live in a certain area that is optimal for such positions.
Thus, the answer is D.
