When scientists approach a problem to solve, they will often start by gathering information. You and your friends decide to do the same. The park ranger helps out by giving you a map of the park with information about the surrounding areas. 1.What information can you get from this map that is relevant to the problem being solved?
2.What further information do you need to gather to solve this problem? What investigations do you think you should conduct in order to test your predictions?
3.Based on the information you have gathered about the areas surrounding the pond, have your predictions about the cause of the algal bloom changed? Write what you now think the main cause is and the reasons for your new predictions

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
