Did any of the substances travel against their concentration gradient? Explain why or why not. No – In facilitated diffusion‚ substances can only move down their concentration gradient. Using your results from Chart 2‚ what was the fastest rate of facilitated diffusion recorded? 0.0038 . Describe the conditions that were

Baker’s Cyst Anatomy And Physiology To better understand a Baker’s cyst‚ it helps to understand the anatomy of the knee joint. A cyst is a lined sac that contains fluid. Cysts that form around joints are due to a bulging of the joint capsule. A Baker’s cyst develops from the knee joint capsule. It protrudes into the tissues in the back of the knee. Four bones come together at the knee joint: * Patella/Kneecap - The patella is a small‚ flat‚ round bone that articulates with the femur in

Nicole French M1-discuss the role of energy in the body In our bodies we need energy so that we could do things that are possible such as; move our muscles‚ talk and all the other things that we do. Without energy all people would be useless not being able to do anything. Energy is needed to extract the oxygen from the areas in our bodies and diffuse it into our bloodstream. As warm blooded people we can only digest food and function if our bodies are at a certain temperature and have enough energy

Week 1 Chapter 1 1. What is the basic difference between anatomy and physiology? (p. 2) ANSWER: Anatomy (a-NAT-ō-mē; ana- = up; -tomy = process of cutting) is the science of structure and the relationships among structures. Physiology (fiz′-ē-OL-ō-jē; physio- = nature‚ -logy = study of) is the science of body functions‚ that is‚ how the body parts work. 2. Define each of the following terms: atom‚ molecule‚ cell‚ tissue‚ organ‚ system‚ and organism. (p. 6) ANSWER: AtomUnit of matter that makes
