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:
If the mass of one of the objects is doubled, then the force of gravity between them is doubled. Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces.
