Explanation:
Food gives us energy and builds our body. If we do not eat regularly, we will become weak.
Photosynthesis is c because plants "exhale" into the atmosphere.
If you are referring to the first question then it is probably A but there's no way to know because we can't see all of space but the milky way is inside the universe not the other way around and therefore it can't be B or C and D just doesn't make sense.
Answer:
The correct answer is D) Inhibits cell wall synthesis.
Explanation:
Antimicrobial drugs are drugs that act against microbes like bacteria, fungus, virus, protozoa, etc. These drugs must be specific and should not harm the host cells but must be effective against microbial cell.
Both microbes and humans contain proteins, cytoplasmic membrane, and nucleic acid therefore antimicrobial drugs that target these structures can harm the host cell.
As human lack cell wall, therefore, the antimicrobial drug which inhibit cell wall synthesis will not be able to harm humans and will selectively kill the cells that contain cell wall like bacteria. Therefore the right answer is D.
