- Read the following scenario then answer the questions below - be as specific as you can. Bob started preparing for his food cart lunch service at 6 a.m. He pulled the hamburgers from the freezer and put them in a pan near the stove to defrost. He washed his lettuce and tomatoes, sliced them, placed them in pans, and put them in the reach-in. He got out the onions, sliced them, and sautéed them for later service for patty melts, placing the cooked onions next to the stove so that they would be convenient. At about 10 a.m., he marked his burgers on the grill, cooking them to 110°F. He then placed them in a pan with some beef stock in it, so that they would stay warm. At noon, he was open for business. Several customers bought hamburgers that day, and some got patty melts. Two days later, the health inspector pid Bob a visit. Several of his patrons had gotten quite ill. 1. List Bob's four main mistakes. 2. At what temperature should he have kept his products stored before cooking? 3.…(Select all that are correct) What are the key characteristics that define a material to be a biomaterial?

- Add 2 teaspoons of detergent, 1 teaspoon of salt, and ½ cup of water to one of the plastic cups. Stir well. Reseal the bag. Making as few soap bubbles as possible, gently mash the fruit for another minute. Place the coffee filter inside the second plastic cup. Open the bag of mashed-up fruit and pour it into the coffee filter. Gently squeeze the remaining liquid into the cup. Add rubbing alcohol to the cup of extracted fruit liquid. To do this, carefully pour down the edge of the cup the same amount of ice cold rubbing alcohol as there is liquid. This separates the DNA from the rest of the fruit cellular debris. Observe the cloudy, white substance that forms on top of your fruit extract. DNA is not soluble in alcohol (especially if it is very cold), so where is the DNA? Tilt the cup 45 degrees. Collect the DNA using the plastic coffee stirrer/wooden stick/spoon. Why can you see big globs of DNA now, but you don’t see them when you’re eating your food?
