- Circle the letters of the regions of the visible spectrum in which chlorophyll absorbs light very well.
a. blue-violet region
b. green region
c. red region

A) Blue-violet region.

Explanation:

Plants tend to absorb blue or violet light better than both green and red because their wavelengths are closer to UV rays. Red light is about average, and green light doesn't really help plants grow that well, maybe only a little bit depending on the scenario.

Have a nice day! :)

"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."

i believe the answer would be b. hope it : )
