D. Populations evolve as natural selection results in a change in the frequency of alleles within the population over time.
Our current understanding about how species evolve is natural selection produces adaptations vital to the survival of organisms.
7)
B. The relative frequency of the mutation will increase as time passes.
The information provided makes it clear that the mutation is an advantageous mutation; according to the theory of natural selection, since the mutation is beneficial to the bacteria, those with the mutation will survive and reproduce more, passing on the mutation. This way, the frequency of the mutation will increase.
Seymour Benzer used phage T4 mutants, Experimental
evidence that a gene is a linear sequence of nucleotide pairs. Some regions of
chromosomes have "hot spots" for mutations. Benzer's experimental
approach to fine structure mapping of the rII locus. Generated 1612 spontaneous point mutations
and several deletions in rII locus identified two complementation groups, rIIA
and rIIB. Mapped locations of deletions
relative to each other using recombination.
Mapped locations of point mutations relative to the deletions. Tested
for recombination between all point mutations within the same complementation
group.
This is possible because of the length of the protein. It is always possible to add more amino acids and synthesize new protein and every new addition increases the number of possibilities drastically.
Answer:
"Cows that eat apples can get a bloated stomach and die. But that's not what's happening when your cattle feed on apples fallen on the ground or those that you offer them to diversify their diet. ... So, if you plan to introduce apples into your cows' diet, do so gradually."
So your best choice is option A!
