and the internal intercostal muscles contract. 2. What was the FEV1 (%) at the initial radius of 5.00 mm? 74% 3. What happened to the FEV1 (%) as the radius of the airways decreased? FEV1% decreased as the airway radius was decreased. 4. Explain why the results from the experiment suggest that there is an obstructive‚ rather than a restrictive‚ pulmonary problem. The FEV1% decreased proportionally as the radius decreased. Review Sheet Results 7-2 5. What lung values changed (from those of the

around the Game World • Understand what are and how to use variables Practical You have already created a simple game using Game Maker in your last lab. In this lab we will build on our existing knowledge and create the first part of the Bugs Shooter Game. The second part of the game will be done in the next lab session. The Game Idea You may be familiar with a genre of games known as Top-down shooters‚ where you usually control a plane which moves in the bottom of the

The Molecules of Cells (Chapter 3 in your textbook) Without water and carbon-based molecules‚ no life as we know it! Carbon: The Backbone of Life • Living organisms consist mostly of carbon-based compounds Also‚ H‚ N‚ O‚ P‚ and S…… • Carbon is unparalleled in its ability to form large‚ complex‚ and diverse molecules. Why? Principal source of carbon on Earth? • Proteins‚ DNA‚ carbohydrates‚ lipids‚ and other molecules that distinguish living matter are all composed of carbon. C21H36N7O16P3S Coenzyme

flow of ions following the concentration gradient of traveling from an area of high concentration to areas of low concentration. The higher concentration gradient would result in a reduced diffusions of K+ ions out of the neuron via the leak channels. 2. Explain why increasing extracellular K+ causes the membrane potential to change to a less negative value. How well did the results compare with your prediction? Your answer: By increasing the extracellular K+ the membrane potential will change to be
