Discuss the steps in generating an action potential in a neuron. (Make sure to include which ion channels are activated and how, changes in membrane potential as a result of the movement of those ions, the different phases seen in an action potential, and the movement of the action potential in relation to the anatomy of a neuron.).

Explain the role of pressure gradients in the cardiac cycle. Your answer should state the relationship between pressure gradients and blood flow. For each phase of the cardiac cycle, describe how pressure changes influence the direction of blood flow and the opening and closing of valves in the heart.

Discuss skeletal muscle contraction beginning with the Action Potential arriving at the Neuromuscular junction and ending with relaxation. (Make sure to include which ion channels are activated and how, changes in membrane potential as a result of the movement of those ions, and WHERE ATP IS USED – 3 PLACES!!!).

a)A small conducting ring is placed inside a solenoid and is concentric with the axis of the solenoid. If the current in the solenoid changes direction, explain what happens to the magnetic flux through the ring.

b)Explain how a uniform magnetic field (one constant in magnitude and direction) can be created.

1a. What is the significance of the fact that 2 of 3 of the married couples with no children at home are over 50? What market opportunities will that create?
