The following diagram shows the branching tree for four kingdoms and some of their shared derived characteristics. a slanting line is shown. there are four lines drawn vertically on this line at equal intervals. there is a black circle between each pair of these vertical lines. protists, plants, fungi, animals are written on top of each vertical line in order from left to right. common cell is written on the left most end of the sloping line. the second black circle has mostly multicellular written on it. the third black circle has x written on it. what shared characteristic can be written at point x? use complete sentences to explain your answer.

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
