Which of the following options best depicts the flow of information when a gene directs the synthesis of a cellular component? a) rna → dna → rna → protein b) dna → rna → protein c) protein → rna → dna d) dna → amino acid → rna → protein e) dna → trna → mrna → protein

B) DNA → RNA → protein

Explanation:

bal is blood alcohol level. bac will normally be higher in a person with more body fat. so the answer to your question would be, as body fat decreases, the increasing rate of bal decreases.  

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).
