Write a short scientific summary comprising 150 words of your findings from this investigation. Be sure to answer the questions below as well as including your own data and reflections. How many times did your heartbeat in one minute when you took your own pulse?

How many times did your friend or parent's heartbeat in one minute?

If you took the pulse of someone who was a different size or age than you, did you notice a difference in heart rates?

Body size, age, and fitness level are factors in heart rate. Why is this?

When you counted heartbeats over periods of ten, fifteen, and sixty seconds, did you notice differences in the final heart rates? If so, was the difference significant?

Why is the ten- or fifteen-second method of taking a pulseless accurate than counting the beats in an entire minute?

After you ran in place, what happened to your heart rates? Why do you think this took place?

What did you find out from this experiment? Be thoughtful in your answer.

The  central dogma  of molecular biology is centered upon the process of protein synthesis, in which the information from dna is transcribed and translated, resulting in multiple amino acids being joined to form a)lipidsb)proteinsc)carbohydratesd)nucleic acids

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
