Stem cell research is another ethical issue. Stem cells are cells from an early embryo that can become any type of cell like a heart, lung, liver, or skin cell. The reason people are researching these cells are because you can actually grow new tissues and organs to replace damaged ones. For instance, it may be possible to grow a new set of lungs for someone dying of lung cancer. The ethical issue with this type of research is that in order to get this type of stem cells you have to destroy an embryo so it will never grow into a person. Do you think this research should be done? Why or why not?

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.
