a) this means that his weight was 25% more than baby boys his age and 75% less than baby boys his age. He's in the low percentage of weight and his weight is smaller compared to a large percentile of other baby boys.
b) at 8 months old. Where most baby boys' weight would be more than 8 kg and his is barely over 6 kg. This shows that the estimated increase of atleast 500g weight of a baby is not displayed by his chart and it shows he's undergrowth.
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.
