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.
The structural unit of compact bone is called an osteon, or sometimes referred to as a Haversian system. Compact bone is made up of many osteons
The answer is FORENSIC ANALYSIS DETERMINING THE GENE FUNCTION. Because researchers observe reverse genetics which is an experimental molecular genetics technique that allows researchers to educate gene function
D: needs to be present on both chromosomes to be expressed
Why: Because if there was a dominant trait present, then the dominant trait would overpower the recessive trait regardless of the matter.
321mL times 6 equals to 1926mL
1926mL in Liters is 1.926L
