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

Reviewing natural selectionhtquick checkmatch each scenario with the correct component of natural selection. on average, sea turtles lay about 110 eggs in a clutch. however, only a fraction of thebaby turtles make it to the ocean. then, an even smaller number have offspring of their own." while all zebras have stripes, no two zebras share the same stripe pattern. a lemur species called aye-ayes have very long, thin middle fingers that allow them toreach into holes in trees and dig out bugs to eat. done7intro
