The correct answer for the given question above would be option D. The fourth sentence. The fourth sentence has a subject-verb agreement error because its subject "they" does not agree with the verb "decides". Since the subject is in a plural form, the verb should take the plural form too. Instead of "decides", it should be "decide".

In general, why might cell-wall inhibiting antimicrobial drugs be less effective on gram-negative bacteria compared to gram-posi
asambeis [7]

Cell-wall inhibiting antimicrobial drugs be less effective on gram-negative bacteria compared to gram-positive bacteria because the outer membrane of the gram-negative bacteria inhibits penetration of the drug and the peptidoglycan found in gram-positive bacteria is structurally different from that in gram-negative bacteria.  

Answer: Option B & C

<u>Explanation:</u>

Antimicrobial drugs are induced into a body to act on that particular selective bacterium which causes disease. When antimicrobial drugs are injected they act efficiently on the gram positive bacteria inhibiting the proliferation of the cells by acting on the cell wall so that cell multiplication doesn’t happen.

On the other hand it is hard to act on the gram-negative bacteria as it has a cell membrane that inhibits drug penetration into it. Both cell walls contain peptidoglycan but in the gram-positive is more assembled and layered while in the gram-negative it is just a thin layer. As gram-positive is thick layered it provides place for another molecule to attach to it but the thin layer in gram-negative inhibits it.

yanalaym [24]

Answer:

C. Helicases

Explanation:

Helicases to be termed as enzymes that is blind and contains acid i.e. remodel nucleic or have protein i.e. nucleic acid. It is important as the time of DNA replication as it divided the DNA i.e. double stranded into one single standard that permits each and every strand for copied it

Also it cracks the bonds i.e. hydrogen that lies between the two strands this could create a replication fork.

Therefore in the given case, the helicases is affected
