This is a typical grassland food web. It is also a small picture of an important cycle on Earth: the carbon cycle. Explain how the carbon gets into this food web.
A)
Bacteria and fungi, the decomposers, recycle carbon from dead organisms.
B)
Carbon is found in the grass and is passed from one level to the next in
this food web.
All living things give off carbon dioxide as a by-product of respiration and
it is released into the atmosphere.
Plants use carbon dioxide as a reactant in photosynthesis, to make usable
chemical energy in the form of a sugar.
D)

answer: c

explanation:

they fuse to form they have half as many chromosomes as a somatic cell of the same individual. b

"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."

c should be the answer
