Which describes the basis of an immunoassay? An electron beam excites atoms within the drug, which give off a characteristic
X-ray spectrum.

The drug gets carried through a stationary phase by a mobile phase and the
retention time identifies the drug.

The drug fragments have specific molecular weights that bind to the antibodies.

The unknown amount of drug in a sample competes with a known amount of
fluorescently labeled drug for binding to an antibody to that drug.

The lake of the ozarks is a human-made lake, so it collects runoff from coal strip-mining, fertilizers, resort wastewaters, and septic drainages. the average lake temperature is between 10∘c and 21∘c. consider the physical requirements for growth and multiplication that would allow fecal coliforms to “blossom” in the lake of the ozarks. which of the following would accurately describe these organisms? check all that apply. psychrophiles facultative halophiles extremophiles mesophiles hyperthermophiles
