Place the following steps in order for motor control.
1. upper motor neurons stimulate lower motor neurons.
2. sensory information is relayed back to the cerebellum so movement can be modified if needed.
3. upper motor neurons in the premotor cortex select a motor program.
4. lower motor neurons stimulate a skeletal muscle to contract.
5. the basal nuclei enable the thalamus to stimulate upper motor neurons of the primary cortex.
a) 3, 5, 1, 2, 4
b) 2, 5, 3, 1, 4
c) 3, 5, 1, 4, 2
d) 5, 3, 1, 4, 2

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
