Activity 1 1. Increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels because the membrane is permeable to K+ ions. Therefore‚ the K+ ions will diffuse down its concentration gradient from a region of higher concentration to a region of lower concentration. 2. Increasing extracellular K+ causes the membrane potential to change to a less negative value because the K+ ions diffuse out across the membrane. My results went well compared to my prediction

Respiratory Acidosis and 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? No‚ it stayed at 7.4 5. Was the pH level always within the “normal” range for the human body? Yes 6. Did the PCO2 level change during the course of normal breathing? If so‚ how? No‚ it stayed at 40mm Hg Activity 2a: Hyperventilation – Run 1

Level 1: Certificate in Counselling Exercise 7 For this exercise I had to interact with a friend and find out about a recent emotional experience. One that did not necessarily need counselling but one which has aroused different feelings. During this interaction I was to try and make all my responses reflections and ask no questions. The idea of this was a little daunting as through-out ones life we are taught or learn conversations with a dictated question and answer scenario. We believe that
