When the lac operon controls the expression of proteins in the E.coli cell that can break down lactose into two sugars, glucose and galactose. When lactose is present, it binds to the repressor that typically sits on the lac operon, changing the repressor's conformation such that it can no longer bind to the lac operon. Because of this, RNA polymerase can now transcribe the gene into mRNA, <span>which in turn is translated into the proteins that can break down lactose.</span>
Alleles on homologous chromosomes determine traits.
Answer:
C) Rodents with black fur color will decrease in frequency as they are more visible to the predator against the light sand background.
Explanation:
As we know that the area that the rodents were released has a light color and a rodent predator, we can conclude that the black-colored rodents will be the ones that will be most captured by the predator and will decrease its frequency. This will happen because the brown and tan rodents are more similar to the color of the place and therefore will be able to stay camouflaged, making it difficult for the predator to see them, this does not happen with the black rodent that will be easily seen and captured.
