In 1973, Stanley Cohen and Herbert Boyer inserted a toxic gene from an African clawed frog into the plasmid of a bacterium. The bacterium then began to produce the toxin. How did this discovery most
impact society?

Group of answer choices

It demonstrated how a DNA toxin from one organism can be used to kill another organism.

It revealed that bacterial DNA can be used to make an entirely new DNA strand.

It led to other life-saving chemicals being produced by recombinant DNA.

It allowed other toxic chemicals to be produced from genetically engineered frog DNA.

The first amino acid of a new polypeptide chain is

When the oxygen produced by photosynthetic plants in the water dissolves in the water, which of these is being formed?

After frida stops exercising, she continues to breathe heavily. what is most likely occurring in her body? heavy breathing during exercise has produced an oxygen surplus in her muscles. this oxygen is being transported to her lungs. this is a result of aerobic respiration. heavy breathing during exercise has produced a carbon dioxide surplus in her muscles. lactate is being transported to her liver. this is a result of aerobic respiration. strenuous exercise has caused her body to be in carbon dioxide debt, and she is breathing hard while lactate is transported to the liver. this is a result of anaerobic respiration. strenuous exercise has caused her body to be in oxygen debt, and she is breathing hard while lactate is transported to the liver. this is a result of anaerobic respiration.
