Question 20 (Multiple Choice Worth 3 points) (07.05 MC)
A burned body is found after a warehouse fire. You cannot obtain nuclear DNA suitable for testing, but you are able to
challenge will you encounter when trying to identify the person using mtDNA?
Everyone has the same mtDNA so you won't be able to narrow identity down.
mtDNA is most useful for information on traits like hair color so it won't narrow things down much.
mtDNA only shows patrilineal lineage so it will only show the father's mtDNA.
mtDNA is time consuming and expensive, not all labs have the capabilities to test this
Question 21

x would be the most and the least would be y because there are more fruit   and seeds than flock z has insects

"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."

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.
