Scientist treats a population of bacteria with a combination of mutagens, including high-energy radiation and certain chemicals. Which is the MOST LIKELY benefit of this treatment? A. The genetic variation of the population decreases, allowing the bacteria to be easier to kill. B. The genetic variation of the population increases, and some of the mutants may have useful properties. C. Many bacterial genes are deactivated, making the bacteria less harmful. D. The bacterial genome increases in length, and some of the new genes may have useful products.

The genetic variation of the population decreases, allowing the bacteria to be easier to kill.

Explanation:

hydrogen is a compound or a single element and a element is a pure substence that cannot be separated into simpler subtances

clorine is a compound its a chemical substance that forms when two or more different elements combine

so both hydrogen and clorine are compounds

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms
