scientists are using dna fingerprinting to identify the bodies of those killed in the 9/11 tragedy. most on-site evidence is in the form of bones or teeth. yet the evidence supplied by the victims' families may include hair or tooth brushes.
how are scientists able to compare dna from bones or teeth to that found in hairs on a hairbrush?
a) they cannot and this is making body identification very difficult.
b) each sample provides an exact karyotype for genetic identification.
c) dna is the same in every cell of the body and does not change over time.
eliminate
d) the dna is close enough from both sources to infer the victim's identity.

Cultures of the lake of the ozarks water samples were grown on enrichment media for identification. however, these organisms are present to some degree in all samples. an important question from a clinical perspective is whether or not there is a significant increase in the fecal coliform populations that would put people's health at risk. if you were part of the team investigating this outbreak, how would you best enumerate the fecal coliform threat? view available hint(s) cultures of the lake of the ozarks water samples were grown on enrichment media for identification. however, these organisms are present to some degree in all samples. an important question from a clinical perspective is whether or not there is a significant increase in the fecal coliform populations that would put people's health at risk. if you were part of the team investigating this outbreak, how would you best enumerate the fecal coliform threat? direct microscopic counts filtration count culture serial dilution count culture plate count culture
