14. Operons allow prokaryotes to
Vladimir79 [104]
14: Operons allow prokaryotes to replicate DNA at the appropriate time.

Operons are specific regions of genes that are linked to a singular process. They ensure that the expression of these genes does not go unchecked and only occurs when necessary. Two key examples of this in humans are the lac operon and trp operon. 

15. The central dogma of molecular biology is:

DNA to RNA to Proteins

Protein Synthesis occurs in 3 steps.

Explain how the use of a chemical designed to kill grasshoppers could reduce the population of peregrine falcons.
Butoxors [25]
Peregrine falcons have a wide diet, including many types of smaller birds. These birds eat bugs like grasshoppers. So, if the grasshopper population decreases, then the birds who are a food source to peregrine falcons will also have a lower population. This means that there is a lesser amount of food for the peregrine falcons to eat, so their population will decrease as well. 

Good luck with your problems!
