#1 Gracie is a 30 year old female, 5 foot 8 in, 140 pounds. Training for marathon. She needs to eat
to maintain energy expenditure and improve
performance. For the past month, she has been
feeling super tired after her long runs and has
struggled the next day. You suspect nutrition is
the culprit. What are Gracie's Carbohydrate and
Protein needs? How would you educate Gracie in
basic nutrient needs for her activity (Carbs,
Protein, Fats, Vitamins and Minerals) and the
proper timing of her eating.

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
