Some antibiotics destroy disease-causing bacteria by entering the bacterial cells and interfering with the critical life processes that keep them alive. However, antibiotics are
*not able to destroy viral infections because
viruses are not cells, so they do not perform the processes that antibiotics normally disrupt.
O the wall surrounding a virus cannot be penetrated by antibiotic chemicals.
O viruses are constantly moving, so antibiotics cannot reach them.
antibiotics are destroyed by the protein coating that surrounds the viral DNA.

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
