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.
final stage in meiosis also in mitosis which that most of these are highly separated to reach to other chromsomes that divide nuclei
In engineering and the physical sciences, experiments are a primary component of the scientific method. They are used to test theories and hypotheses about how physical processes work under particular conditions, whether a particular engineering process can produce a desired chemical compound

Answer:
Polygenic inheritance occurs when one characteristic is controlled by two or more genes. Often the genes are large in quantity but small in effect. Some examples include height, skin color, eye color and weight.
- In polygenic inheritance the "dominant" capital genes are additive, each capital gene adding one unit of color to the genotype.With more capital genes, the phenotype (appearance) gets darker.
The answer is common ancestor.
Since these two organisms are adapted to different environments and still have structural similarities, that means that they must have a common ancestor. Common ancestor is an ancestral organism that two or more descendant lineages have in common.
