analyze the example of gene expression of the bacteria below: A piece of DNA is transcribed into a piece of mRNA. The mRNA is translated in a protein. The protein has a chemical bonded to it that allows the protein to bond to a second piece of DNA. The protein chemical substrate prevents the second piece of DNA from being transcribed into mRNA. Why would the bacteria regulate gene expression in this manner? To express genes during reproduction To ensure gene expression when the initialing chemical is present To prevent gene expression if the initialing chemical is already provided To make sure the genes are constantly being expressed

How are rocks that cooled within magma chambers found on earth’s surface today? they are pushed up by magma under earth’s surface. they are revealed by erosion of earth’s surface over time. they are pushed to earth’s surface because of their larger size. they are revealed at earth’s surface due to their low density.

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
