Drug-resistant populations of microbes arise when

Biology
1 answer:
lozanna [386]3 years ago

Answer:

The correct option is D. Drug-resistant populations of microbes arise when  exposure to drugs selectively kills sensitive cells, allowing overgrowth of resistant cells.

Explanation:

Drug- resistance can be described as a mechanism through which an organism can overcome the effect of a drug.

Usually, exposure of a drug again and again to a population of microbes will make the microbes resistant to that drug. The cells of the microbes undergo some change to overcome the effect of that particular drug.

A population of drug-resistant microbes might occur when the sensitive microbes get killed by the drug and resistant strains remain alive.

Answer:

The correct answer will be- the planets and moon also exhibit hydrothermal vents, volcanoes and rocks.

Explanation:

Scientists have always tried to understand and explain the origin of life on Earth and predicted that life on earth originated as a result of the conditions created by the distance of the Earth from the Sun.

Later discoveries found that life exists even in the harsh conditions on Earth-like hydrothermal vents and inside sub-surface of the rocks. This shows that life can exist in extreme conditions.

Since the planets other than Earth posses such hydrothermal vents, rocks and volcanoes, therefore scientists predict that life could be found on other planets.
