Answer: The correct answer is-
B. by mutating their DNA in response to environmental conditions to gain beneficial traits.
Antibiotic resistance in bacteria means the bacteria is not susceptible to the antibiotic that is the effectiveness of antibiotic against the bacteria is eliminated or reduced.
It occurs when bacteria undergoes mutation that is alteration in the genetic material ( for instance, in one mechanism of resistance, mutation changes the protein that was earlier target for the antibiotic).
Therefore, by mutating the DNA in response to environmental condition ( such as exposure to antibiotic in this condition), bacteria gains beneficial characters and become resistant.
Thus, option B) is the right answer.

Answer: The auditory cortex
Explanation:
The temporal lobe is primarily involved auditory perception which includes hearing, processing and understanding. The temporal lobe houses the primary auditory cortex.
The primary auditory cortex collects sensory information from the ears and other secondary areas, it processes the information into meaningful terms such as speech and words.
All of the cells in an organisms have the same genetic information.
Your skin cells has the same exact DNA as every other cell in the organism.<span />
