Graded Unit Plan Interpretation Of The Brief The graded unit is a piece of work that will showcase my skills that I have attained whilst studying the HND course and it will present my knowledge of the music business to the best of my ability. With this piece of work‚ it should open a lot of doors as a future employee to the music industry. The graded unit project consists of a project and an interview that will take place with someone‚ whether that is an employer or someone who has had a

Impulses Activity 1: The Resting Membrane Potential 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels. Increasing the extracellular K+ causes the membrane potential to change to a less negative value because when K+ ions diffuse out across the membrane they are leaving behind a net negative charge. 2. Explain why increasing extracellular K+ causes the membrane potential to change to a less negative value. Potassium

membrane potential when extracellular K+ concentration is increased? -The resting membrane potential will become more positive when K+ concentration is increased. 2. Explain why the resting membrane potential had the same value in the cell body and in the axon. -The resting membrane potential has the same value in the cell body and the axon because the typical resting membrane potential is the same throughout the entire neuron. 3. Describe what would happen to the resting membrane potential if the

Your answer: By increasing the extracellular K+ the membrane potential will change to be a less negative value. By adding more extracellular K+ the intracellular K+ will decrease and cause the membrane potential to become less negative. This result in a increased postitve membrane was what we predicted during
