While doing a pedigree analysis of a european royal family, you notice a disease in a female child of two healthy parents. there are also some cousins with the same genetic disease. if this disease is controlled by a single gene, then the most likely explanation for these observations is that the disease is:
a. the disease is recessive and only seen in homozygous recessive individuals such as the daughter. b. the disease is a spontaneous mutation. c. the disease is dominant and is seen in homozygous dominant or heterozygous individuals. d. the disease is only seen in heterozygous individuals such as the daughter. e. the disease is dominant and only seen in homozygous dominant individuals such as the daughter.

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
