Which three statements may correctly explain why the population size increases after time point C?a. Bacteria that acquired a mu

tation that conferred drug- resistance had a growth advantage over non-resistant bacteria.b. The population increase just after time point C indicates that antibiotic use was discontinued.c. Between time points C and D, drug-resistant bacteria were reproducing faster than non-drug resistant bacteria were dying.d. The few drug-resistant bacteria in the population reproduced, quickly leading to a large drug- resistant population.e. Because the population grew more rapidly after time point C, the bacteria must have acquired a second drug- resistance mutation.

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.

Antibiotic resistance happens naturally due to genetic mutation through random selection, however, genetic drift occurs on purpose and tests which genes are stronger and should continue to be passed on to future generations. In most cases, genetic drift is needed and antibiotic resistance isn’t.

I) Predict which of the liquids would cause the largest decrease in mass of a potato stick
rjkz [21]

Answer:

1.0 mole per dm3 sodium chloride solution

Explanation:

<em>The more the molarity of a solution, the lower the water potential of the solution, and the higher the amount of water that will osmotically move from the potato stick to the solution when placed in it in order for an equilibrium to be established. </em>

Hence,<u> the 1.0 mole per dm3 sodium chloride solution will cause the largest decrease in the mass of the potato stick</u> when compared to the 0.5 and 0.1 mole per dm3 sodium chloride solutions.
