Note: Question is Incomplete i have added full question in picture format. And marked correct answers.
Answer:
This question is about antibiotics resistance development in bacteria over time. Resistance develop only when we overuse these antibiotics. Resistance development in bacteria lead to their exponential growth resulting in more infections.
Also See attachment for full question and answer.
The true statements are:
A. Because the population grew more rapidly after time point C, the bacteria must have acquired a second drug- resistance mutation.
C. Bacteria that acquired a mutation that conferred drug- resistance had a growth advantage over non-resistant bacteria.
D. Between time points C and D, drug-resistant bacteria were reproducing faster than non- drug resistant bacteria were dying.
Answer:
Pollination is a form of sexual reproduction and adds new gene combination to the progeny. These new gene combinations impart new genetic traits to progeny.
Explanation:
Pollination includes landing of pollen on the stigma of the same flower or another flower of same species. Since it is followed by fusion of male and female gamete to form an embryo, new gene combination and new genetic traits are imparted to the progeny.
Since the Dr studies genetic traits, sexual reproduction in the plant would allow him to observe more genetic variations in the traits.
Because it’s in smaller price so therefore can’t melt faster than the block, since the smaller peices will melt at the same time as one another.
