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:
The conversion of stored potential energy into kinetic energy can also be harnessed to power homes, factories and entire cities. The most notable example is the Hoover Dam. The Hoover Dam is an arch-gravity dam by design. This design name is the first clue as to how exactly the dam harnesses energy.
Answer:
All of the above are true.
Explanation:
The structure and function of components of the nervous system are altered by the process of aging. In late adulthood, there is alteration in the neuromuscular junction and the nerve conduction velocity is also reduced.
The age-related slowed response of the nervous system is a result of the loss of nerve fibers from the peripheral nerves with aging. Both myelinated and non-myelinated nerve fibers of the peripheral nervous system are affected by aging and are lost resulting in slowed conduction of nerve impulse.
