A substance that enters into a Chemical reaction is called an reactant.
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.
Answer:
An asteroid impact.
Explanation:
An asteroid impact is considered to have tossed rubble across the earth, killing off many species of plants and animals, 65 million years ago. Volcanic activity is involved in at least four mass extinctions, whereas an asteroid in just one.
Photosynthesis is the process by which green plants make their food by tue help of sunlight and chlorophyll using carbondioxide and water to form oxygen and glucose
cellular respiration-cellular respiration definition. The chemical process that generates most of the energy in the cell, supplying molecules needed to make the metabolic reactions of an organism run. Note: The main carrier of energy in metabolism is the molecule ATP.
