Aseptic Technique and Culturing Microbes‚ Lab #3 Purpose: The purpose of the this experiment is to learn to transfer microorganisms to a nutrient medium to promote growth using aseptic techniques. which are a method used to prevent unwanted organisms from contaminating a medium. We will also learn about different types of culture media‚ including MRS broth and nutrient broth‚ learn about oxygen and temperature requirements for microbial growth and how to control microbial growth. Procedure:

1. What is the molecular weight of Na+? 22.99 2. What is the molecular weight of Cl-? 35.45 3. Which MWCO dialysis membranes allowed both of these ions through?50‚ 100 and 200 4. Which materials diffused from the left beaker to the right beaker Urea‚ NaCl and glucose diffused 5. Which did not? Why? Albumin‚ because it is too large to diffuse Activity 2: Simulating Dialysis 1. What happens to the urea concentration in the left beaker (the patient)? Its concentration gradient

Q. A young hiker has been on a long walk. He is now sitting in front of a small campfire‚ drinking a hot cup of soup. It is dark and a frost is beginning to form on his tent. Explain the hiker’s heat gains and losses‚ and what mechanisms would come into effect to keep his temperature at the desired 37ºC. Humans are subject to vast changes in environmental temperatures‚ but our complex biochemical systems have a major limitation in that enzymes only operate within a relatively narrow temperature

This assignment will describe the role of energy in the body and explain the physiology of two named body system in relation to energy metabolism. It will explain where energy comes from‚ how the body uses energy‚ what is metabolism/catabolism and anabolism and also it will explain cellular respiration aerobic/anaerobic is. Energy is necessary for muscular activity and movement however‚ energy is also necessary to circulate blood and lymph and tissue fluid throughout the body; for breathing and
