DDT and other pesticides used over 50 years ago are still affecting the
environment today. Scientists have found these substances in recent
glacier runoff. Glacier runoff occurs during the summer, when precipitation
that has fallen on glaciers during the winter is released. Ice layers from
existing glaciers have been analyzed. The results of this analysis show that
the concentrations of DDT and other pesticides were highest about 10
years after the use of these substances was banned. This information
shows that *
A. DDT and other pesticides cause glacier runoff during the summer.

B. it takes humans over 50 years to analyze a glacier.

C. Precipitation helps to break down pesticides.

D. The decision of one human generation may have an impact on future generations.

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.
