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.

Which of the following have been linked to the dramatic global decline of amphibian populations? Select one: a. drainage of wetl
charle [14.2K]
<h2>The correct answer is: e.</h2>

Explanation:

  • Decline in the global population of amphibians is due to multiple reasons which include:
  1. A moist ecosystem is necessary for amphibians especially for the purpose of their reproduction. The drainage of the wetlands deprives them of their habitat.
  2. Pollutants adversely affects the survival of the gametes, tadpoles or the adult amphibians by acting as toxic agents and inhibiting their normal metabolic function.
  3. Infectious diseases often cause their death resulting their population to decline.
  4. Global climate warming affects their normal metabolic growth and development and hence causes their population to decline.
