6. What does the LUC gene specify? Are enzymes that emit light. (Luciferases)
7. a. The RNA polymerase makes a copy of the LUC gene in what form? In the form of mRNA (similar to DNA)
b. Once transcription is complete, where does the mRNA go next?
8. What is the cell's protein-making machine?
9. What is the being make through the string of amino acids?
10. What must happen in order for the LUC gene to become active?
11. In order for the firefly to produce visible light, how many luciferase enzymes must be produced at
once?
12. What chemical does the luciferase seek to bind with?
13. What molecule is the luciferin combing with to form oxyluciferin?
14. Why does the firefly emit the light produced in this reaction?

You have been asked to lead a demonstration for the undergraduate microbiology lab course about the uses of negative staining when studying bacteria. a "negative" stain does not stain the bacterial cell itself but stains the space between cells. under magnification, the acidic (negativelycharged) nature of the stain will be repelled by the negatively charged bacterial cell wall and willleave the cell colorless in a stained background. negative stains are used primarily to reveal the presence of negatively charged bacterial capsules; therefore, they are also called capsule stains. encapsulated cells appear to have a halo surrounding them. the negative stain procedure does not require heat fixation, which limits any chances of alteration in bacterial cell shape and size. the bacterial suspension is added to a drop of stain, such as nigrosin or eosin, and drawn across the glass slide using a coverslip.nigrosin staining-not safranin staining-of klebsiella pneumoniae will allow for the visualization of the cell shape and the determination of the presence of a capsule.true/false

The circles, or orbits, for electrons are called energy levels. each level can hold only a certain number of electrons. add electrons to each level until you can't add any more. how many electrons can each level hold?

Recent research by marine biologists suggests that bottlenose dolphins have names for themselves. scientists played sounds they had identified as the names of particular dolphins, putting them through a synthesizer so that they did not sound like the voices of particular dolphins. the researchers found that dolphins would respond to the names of other dolphins that they were related to or associated with, but they ignored the names of strangers. this discovery suggests a much greater degree of self-awareness in aquatic mammals than was previously suspected. if this research holds up, what does it suggest about dolphins?
