Answer:
the process in which energy is emitted by one object, transmitted through space, and absorbed by another is correct.
Explanation:
The transfer of energy is not by movement.
That would be known as the heart.
It has no effect. Density of a substance is the same no matter the size or shape of the sample.
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.
