You are working as a microbiology researcher on a emote island in the Pacific! Tragically, storms prevent the supply ship from re supplying you with food, and you will have to survive on your own for many months. As you consider your options, you realize you have a large supply of tryptic soy medium as well as glucose salts medium, Although not the tastiest food option, one of these would support your survival for much longer than the other. Which of these two should you consume, and why? Explain.

Following from the previous question about being stranded on a remote island in the Pacific, in order to survive, you will of course need to drink water. Although there is fortunately abundant fresh water available in a small pond on the island, your testing has determined it is unfortunately contaminated with fecal coliforms. Devise a simple method you might employ, that does not involve electricity or natural gas, that you might use or treat the water before consumption. You may make any reasonable assumptions you wish, but please fully explain your choice and their impact on potential pathogens.

Imagine you take a gentle scraping of epithelial cheek cells and perform a Gram stain on them. Predict the result in terms of the gram stains. Does this mean you are a Gram negative or Gram positive organism, or are you something else? Explain.
