Fill in the blank.

A/An solution occurs when the solute concentration outside of the cell is higher than the solute concentration inside the cell
Most cells have an electrical potential difference of between –40 and millivolts.
is a determining force in water movement, and causes water to move from areas of high water concentration to low water concentration.
In most cells, there are more molecules inside the cell and more sodium molecules outside the cell.
A/An exists when different concentrations of a substance exist on either side of a membrane.

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
