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:

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 range. Accordingly the human body have anatomical and physiological mechanisms that keep body temperatures within acceptable limits‚ regardless of environmental conditions

ANATOMY & PHYSIOLOGY I WORKSHEET I Plasma Membrane and Cellular Transport Structure of the Plasma Membrane 1. Why do you think it is important to have a membrane surrounding each of our trillions of cells? Expect varying answers‚ but the idea is have the students understand the plasma membrane separates the cells from their environment and each other while also regulating the material within each cell. 2. What are two distinctive physical features of phospholipids? Heads are polar (water soluble

Week 7 Checkpoint: Physiology Assignment I chose to look up a diagram on a sea dwelling organism known as a Jellyfish. Jellyfish have many different forms and are often characterized in different groups. One jellyfish that stood out to me was the Aurelia or also known as the Moon Jellyfish‚ which is like the basic jellyfish that I’ve always seen in pictures and books growing up. Jellyfish are said to be very effective predators‚ as one point in the time they were considered to be at

The first part of digestion would be as soon as you use your sense of smell‚ which triggers your salivary glands to secrete saliva. Once you take your first bite‚ your saliva increases even more. You then break down the food by chewing. Even more saliva
