During periods of intense exercise, cells do not receive enough oxygen to perform the normal process of aerobic cellular respiration. as a result, the cells resort to anaerobic respiration, which produces only 1/20th of the energy produced during the aerobic process. this alternative version of cellular respiration produces lactic acid as waste, which results in muscle soreness. which of the following statements does the above information support?
a
cellular respiration is affected by sugar production.

b.
cellular respiration is affected by cell hydration.

c.
cellular respiration is affected by the availability of reactants.

d.
cellular respiration is affected by temperature.

the answer is C i would know because i just did it.

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
