Which of the following factors drives all the weather on earth, including large-scale storms and local weather systems?

1.the sun heats up the air at different rates, and the atmosphere undergoes changes to equalize temperatures and pressures.
2. the ocean holds thermal energy more efficiently than land.
3.the coriolis effect curves the motion of wind due to the earth's rotation.
4. the greenhouse effect ensures that some thermal energy will always be trapped near the earth's surface.

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
