Here are two considerations: • Some individuals with harmful characteristics can still successfully reproduce, but they have an
overall lower chance of doing so compared to organisms with neutral or beneficial traits.
• Natural selection may affect distribution of traits. It's possible that harmful traits could eventually
disappear from the gene pool.
Don't worry about precise population numbers. Based on your understanding of natural selection, you'll
be modeling only one scientifically plausible trend that can occur. There are several correct variations of
this diagram. You'll explain the justification for your choices in pari E.
Assume that these plants have a life expectancy of about one year, but the rate of reproduction keeps
their population consistently around 2,500 organisms. Using the same elements you used in part C, draw
simulations for year 5 and year 10. Clearly label each simulation.

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
