Question: What Are the Elements in the Human Body? Answer: Most of the human body is made up of water, H2O, with cells consisting of 65-90% water by weight. Therefore, it isn't surprising that most of a human body's mass is oxygen. Carbon, the basic unit for organic molecules, comes in second. 99% of the mass of the human body is made up of just six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus.

I bought the chicken on Thursday and it is now Saturday. I just made a pasta dish with it, and my general rule of thumb is that once cooked meats (poultry, beef, pork) are good for another two days.(Possibly a little conservative I know.) I am thrown by the rotisserie chicken though because it was cooked on...est Answer: I guarantee two is good. Usually 5-6 days are okay for cooked meats that are stored in refrigeration. The main concern then is quality not safety. You have a good (yes conservative) rule so relax. While taking a course in Microbiology we were to bring in a food item. I decided to bring in BBQ beef.
