People will often say about someone that they look like one or other of their parents, or that they have many more characteristics of one parent. Two possible explanations for this are:
1. The child received more genes from the parent they are most like and fewer genes from the parent they
appear to be unalike.
2. The child received the same number of genes from each parent, but the characteristics we notice were
affected more by the genes of one parent and not the genes of the other parent.
Which of these explanations is correct? Explain.

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
