Asap by 8: 30: in order for cells to function properly (and not die), they must undergo homeostasis. this just means they must maintain a consistent internal environment. it’s sort of like when you get really hot: you sweat more to cool off and keep yourself (hopefully) from having a heat stroke. but this kind of adjustment occurs at the cellular level too. cells need to extract energy in order to maintain homeostasis, and they get this energy from nutrients that pass into them. what is the name of this movement of nutrients? what is the name of the movement of water through a cell membrane? briefly describe two other processes that cells use to maintain homeostasis.

What have we learned from fossil evidence about evolution? a) it is an abrupt change. b)the process is observable. c) it takes place during one lifetime only. d)the most complex traits are always 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
