Which three statements provide reasons that scientists are considering renewable sources of energy? most renewable resources are clean and nonpolluting. renewable resources can be replenished. renewable resources are conventional resources. most renewable resources are easily available in nature. all renewable resources are cost effective. a.) most renewable resources are clean and nonpolluting. b.) renewable resources can be replenished. c.) renewable resources are conventional resources. d.) most renewable resources are easily available in nature. e.) all renewable resources are cost effective.

its actually a b and d . Conventional energy means the energy source which is obtained from fixed reserves in nature like oil, gas and coal. In other words conventional energy is also termed as non-renewable energy sources, or fossil fuels. so c is wrong

A.) Most renewable resources are clean and nonpolluting.

B.) Renewable resources can be replenished.

D.) Most renewable resources are easily available in nature.

chordata is the answer

"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."
