Answer:
A,C, D
Explanation:
Bacteria that acquired a mutation that conferred drug- resistance had a growth advantage over non-resistant bacteria.
Between time points C and D, drug-resistant bacteria were reproducing faster than non-drug resistant bacteria were dying.
The few drug-resistant bacteria in the population reproduced, quickly leading to a large drug- resistant population.
There is no indication that a second antibiotic was used, so it is not possible to assume a second drug-resistance mutation occurred. There is also no indication that antibiotics were discontinued.

Answer:
The right answer to the concept whereby sound waves undergo constructive intereference to producing a louder sound in musical instrument would be superimposition.
Explanation:
When sound waves are produced, especially from a musical instrument, numerous beats are produced, which have different frequencies. The sound waves mix with each other in any of Destructive or constructive interference. When the waves are moving in the opposite direction with the same amplitude, they tend to cancel out each other to produce a quieter sound wave. The constructive interference of sound waves results in a wave with an accumulated amplitude of individual waves, thereby producing a louder sound wave. When sound waves are in combination into a higher amplitude is called superimposition.
