Drivers who refuse a law enforcement officer's request for breath, blood, or urine testing when suspected of driving while intoxicated will have their drivers license automatically suspended for no less than a. 15 days b. 90 days c. 180 days

The answer can be either B or C and it depends on the state.

Explanation:

B) 90 days would apply in Alabama, Mississippi, Nebraska

C) 180 days would apply in Massachusetts, New Hampshire and Texas

the answer is true when observing or determining population size, a direct observation is use, in which each organism is counted in a population or in an area. one benefit of this measure is that you get the exact population count but it will take a long time to  determine  the  size  of a  population.

the last one: artificial selection/genetic engineering

plant breeding is modifying the genetic composition of the plant - but this isn't cloning (which is specifically introducing a gene into a genome). but you are artificially selecting for the phenotype that you want.

the second one is literally genetic engineering - the gene would have been cloned first and then inserted or genetically engineered into the new plant cell (the cotton).
