Answer: A virus lack the metabolic machinery common to other microorganisms

Explanation:

A virus is an ultramicroscopic particle capable of causing disease. It differs from other disease-causing organisms like bacteria, nematodes etc, because it has no metabolic system of its own but relies on its host system for survival and replication.

Hence, it is difficult for antibiotics to target and destroy viruses without harming patients, rather antiviral drug are prescribed against viruses

Answer: Due to structural differences between virus and bacteria, antibiotics can't treat viral infections.

Explanation:

Viruses insert their genetic material into a human cell's DNA in order to reproduce. Antibiotics cannot kill viruses because bacteria and viruses have different mechanisms and machinery to survive and replicate. The antibiotic has no “target” to attack in a virus and therefore can't kill a virus.

44. Which of the following choices is NOT a major component of vascular plant leaf anatomy?

Aliun [14]

Answer:

The correct answer is option d. "Elastic channels".

Explanation:

The vascular plants uses xylem and phloem cells that carry water and nutrients to all the parts of the plant, which are present in the leaves of the plant. Stomata is part of the vascular system of a plant, but it serves for gas exchange instead of water and nutrients exchange. Palisade mesophyll is a structural component that contains columnar cells with spaces between them, located in the leaves of vascular plants as well. A component that is not part of the vascular plant leaf anatomy are the elastic channels.
