For Learning Centre use only Activity 1: Simulating Dialysis (Simple Diffusion) Lab Report Review Sheet Results 1. 2. Describe two Variables that affect the rate of diffusion. The two variables that affect the rate of diffusion are: A. The size of the molecule. The larger molecule will diffuse more slowly than the smaller molecule. B. The nature of plasma membrane. If the membrane is composed of lipid portion.‚ only lipid soluble molecules can pass through while water molecules

When the blood circulates within our system‚ chemicals are exchanged by diffusion. Our cardiovascular system is made up of our heart‚ arteries and our veins. There is an important difference between the veins and the arteries. That difference is the flow or direction of the blood. Veins carry blood to the heart and arteries carry blood away from

PET 3351 Exercise Physiology Second Exam Review (Fall 2012) Chapter IV: The Physiological Basis of Muscular Strength and Flexibility 1. Strength is operationally defined as the maximal force that can be exerted in a single effort. Using this definition‚ strength should be assessed using one repetition maximum (1 RM)‚ though we often estimate strength using tests that may involve multiple repetitions. 2. In strength training and rehabilitation‚ emphasis should be given to both the concentric

-------------------------------------------------------------------------------- Experiment Results Predict Question: Predict Question 1: How will the conduction velocity in the B fiber compare with that in the A Fiber? Your answer : b. The conduction velocity in the B fiber will be slower because the B fiber has a smaller diameter and less myelination. Predict Question 2: How will the conduction velocity in the C fiber compare with that in the B Fiber? Your answer : d. The conduction

the: Muscoskeletal‚ Cardiovascular and Respiratory responses to exercise through this unit As soon as you begin to exercise changes begin to happen within your body. Body systems work together‚ to make sure that you have enough energy to perform. Body systems respond both in the Short and Long-term in response to exercise. It is important to understand the changes that happen to the body as a result of physical activity. You will understand the: Muscoskeletal‚ Cardiovascular and Respiratory responses

Mechanism and Physiology of Regeneration in Urodeles 2013 Mechanism and Physiology of Regeneration in Urodeles Urodeles or more commonly known as salamanders are any of approximately 550 extant species of amphibians under the Order Caudata.1 Urodeles’ distinctive factor that makes them different from other amphibians like frogs and caecilians is the retention of a full tail. Frogs actually lose their tail after leaving the larval stage and on the other hand‚ caecilians lack or have a small
