Question 3 (1 point)
which of the following is a correct statement about photosynthetic responses to climate change?
question 3 options:
under higher co2 concentrations, photosynthetic rate is generally expected to decrease
c4 plants are expected to profit more from higher levels of co2 than c4 plants
photosynthetic rate is mostly immune to temperature changes until a certain temperature maximum
under high temperatures, co2 solubility is decreased which reduces the photosynthetic rate

Describe pasteur’s results and how they disprove spontaneous generation.

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

Does anyone know what a poms statement is for biology? i don't know what it is and i have an assignment on it tomorrow, will award the best answer a brainliest!
