The red-cockaded woodpecker is a keystone species in pine forests of the southeastern United States. Red-cockaded woodpeckers feed on insects and nest in cavities that they bore into pine trees. Many other species of animals use these cavities
for roosting and nesting after they are abandoned by the woodpeckers.
If the population of red-cockaded woodpeckers suddenly decreased in a certain forest, which of the following would most likely
occur in the ecosystem over time?
ОА.
an increase in number for populations that are predators of woodpecken
ОВ.
a decrease in the number of pine tree cavities available for other species to nest in
OC. an increase in the number of species that live in pine tree cavities
D
a decrease in competition between other species that nest in pine tree cavities

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
