that both were able to diffuse‚ but at the end‚ only glucose diffused. 4. Put the following in order from smallest to largest molecular weight: glucose‚ sodium chloride‚ albumin‚ and urea. a. Sodium chloride‚ urea‚ glucose‚ albumin Activity 2 5. Explain one way in which facilitated diffusion is the same as simple diffusion and one way in which it differs. a. Simple diffusion moves molecules from an area of higher concentration to an area of lower concentration without an input of energy. Facilitated

Review Sheet Results (1) 1. List the hematocrits for the healthy male (sample 1) and female (sample 2) living in Boston (at sea level) and indicate whether they are normal or whether they indicate anemia or polycythemia. 1. The hematocrit value for the healthy male: 48 2. The hematocrit value for the healthy female: 44 Both values are normal because they are between the normal ranges: for males between 42-52% and for females between 42-47%. 2. Describe the difference between the hematocrits

Objective: To study the conservation of energy and momentum using projectile motion. Theory: The ballistic pendulum demonstrates both the constant horizontal velocity in projectile motion and the conservation of momentum. Because there is no acceleration in the horizontal direction‚ the horizontal component (v_x) of the projectile’s velocity remains unchanged from its initial value throughout the motion. In a closed isolated system‚ if no net external force acts on a system of particles‚ the total

Physio Cardio Lab Report Answers Activity 1 Questions: 1. Explain how the body establishes a pressure gradient for fluid flow. Pressure gradient is the flow rate of a liquid through a pipe. This is directly proportional to the difference between the pressures at the two ends of the pipe and inversely proportional to the pip’s resistance. The pressure gradient is directly dependent upon blood vessel radius which essentially controls blood flow. The bigger the blood vessel radius‚ the more
