Answer:

The correct answer is D) selective toxicity

Explanation:

Selective toxicity refers to the ability of antimicrobial drug to selectively kill or harm the pathogen/microbes without harming the host cell. Therefore a drug who have selective toxicity rarely cause any side effect in the humans.

For example, penicillin is the drug that show selective toxicity because it acts on the cell wall of bacteria made up of peptidoglycan so it do not harm human cell as human cell do not have cell wall or peptidoglycan.  

Therefore as amoxicillin rarely cause side effect in humans and effectively treat infection by gram-positive bacteria therefore it is an example of selective toxicity.

Which of the following intermediary metabolites enters the Krebs cycle and is formed, in part, by the removal of CO2 from a mole
asambeis [7]

Answer:

The correct answer will be option-D.

Explanation:

Before Citric acid cycle or Krebs cycle, an intermediate reaction takes place which converts the pyruvate into Acetyl CoA. This reaction is known as pyruvate decarboxylation as it produces Carbon dioxide.  

Coenzyme A reacts with pyruvate which causes the release of two oxygen atoms and one carbon to form CO₂ along with the reduction of  NAD+ to NADH and produce "Acetyl CoA."

Thus,  option-D is the correct answer.

What is phosphorus used in the soil for
Otrada [13]
Phosphorus is, therefore important in cell division and development of new tissue.
It is also associated with complex energy transformations in the plant. Adding phosphorus to soil low in available phosphorus promotes root growth and winter hardiness, stimulates tillering, and often hastens maturity.

Hopefully this helps :)
