Which statement is BEST supported by the data in the graph? A
The percentage of birds with smaller beaks increased because there was less competition for food with the large-beaked birds.

B
The percentage of birds with larger beaks decreased because there was increased competition for food with the smaller-beaked birds.

C
The percentage of birds with larger beaks increased because they were better able to find food and survive to reach reproductive age.

D
The percentage of birds with smaller beaks increased because they were better able to find food and survive to reach reproductive age.

Keeping in mind the life cycle of bacteriophages, consider the following problem: during the reproductive cycle of a temperate bacteriophage, the viral dna inserts into the bacterial chromosome where the resultant prophage behaves much like a trojan horse. it can remain quiescent, or it can become lytic and initiate a burst of progeny viruses. several operons maintain the prophage state by interacting with a repressor that keeps the lytic cycle in check. insults (ultraviolet light, for example) to the bacterial cell lead to a partial breakdown of the repressor, which in turn causes the production of enzymes involved in the lytic cycle. as stated in this simple form, would you consider this system of regulation to be operating under positive or negative control?
