Part B: Select Audio and Video An audio-visual presentation uses both pictures and words to present information. Follow these tips as you build your presentation:

Limit text: Insert key words or phrases highlighting your points instead of typing your entire speech on the slide.
When possible, use pictures instead of words: Use representative figures such as pictures, graphs, and charts to convey information or evidence rather than huge blocks of text.
Fill in the speaker’s notes: Presentation software includes a notes section where you can add speaker’s notes for your own reference. In this section, you can cover all the details you want to talk without showing them on your slides. Your speaker’s notes should be clear and coherent enough so that someone else could deliver the presentation to an audience. You must complete your speaker’s notes to get full credit for the assignment.
Identify two to three audio, video, or photo resources that you wish to use in your presentation. Use the Insert Image button to add any images you selected.

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
