Review Sheet Results 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels. Your answer: If the extracellular K+ increases then the concentration of intracellular K+ will decrease causing a decrease in the steepness of the concentration gradient and fewer K+ ions would be drawn out. 2. Explain why increasing extracellular K+ causes the membrane potential to change to a less negative value. How well did the results compare

Assignment 1. 1. Summarise the main development of a child from the age range 0-2 years‚ 3-5 years and 5-8 years. 0-2 Years Newborn babies grow extremely quickly. During ‘Infancy’‚ which lasts from birth to eighteen months‚ babies change from a helpless newborn‚ to a child who can lift up their own head at three months‚ sit up unsupported at six months‚ walk at sixteen months and kick and throw a ball at two years old. Newborn babies actually lose some of their birth weight to begin with

ANSWER: 8-4 Trigonometry Express each ratio as a fraction and as a decimal to the nearest hundredth. 1. sin A 3. cos A SOLUTION: The cosine of an angle is defined as the ratio of the adjacent side to the hypotenuse. So‚ ANSWER: SOLUTION: The sine of an angle is defined as the ratio of the opposite side to the hypotenuse. So‚ 4. tan A ANSWER: 2. tan C SOLUTION: The tangent of an angle is defined as the ratio of the opposite side to the adjacent side. So‚ ANSWER: 3. cos A SOLUTION:

Chapter 8: Aggregate Planning in a Supply Chain Exercise Solutions : We define a comprehensive set of decision variables that are utilized in problems 8-1 to 8-3 depending on the problem context. Decision Variables: Ht = # of workers hired in month t (t = 1‚..‚12) Lt = # of workers laid-off in month t (t = 1‚..‚12) Wt = # of workers employed in month t (t = 1‚..‚12) Ot = # of hours of overtime in month t (t = 1‚..‚12) It = # of units (000s) held in inventory at the end of month t (t = 1‚..‚12)

Alkalosis Activity 1: Normal Breathing 1. At 20 seconds‚ pH = 7.4 2. At 40 seconds‚ pH = 7.4 3. At 60 seconds‚ pH = 7.4 4. Did the pH level of the blood change at all during normal breathing? If so‚ how? The pH did not change during the normal breathing. 5. Was the pH level always within the “normal” range for the human body? Yes it was. 6. Did the PCO2 level change during the course of normal breathing? If so‚ how? No it did not change either. Activity 2a: Hyperventilation – Run 1 1
