What are the 6 steps of action potential?
What are the 6 steps of action potential? An action potential has several phases; hypopolarization, depolarization, overshoot, repolarization and hyperpolarization. Hypopolarization is the initial increase of the membrane potential to the value of the threshold potential. What are the 5 steps of an action potential? The action potential can be divided into five phases: the […]
What is the phase shift?
What is the phase shift? The Phase Shift is how far the function is shifted horizontally from the usual position. The Vertical Shift is how far the function is shifted vertically from the usual position. How do you find the vertical shift of a trig function? Step 1: Remember the general form of a trig […]

What is the relationship between air pressure and altitude?
What is the relationship between air pressure and altitude? Pressure with Height: pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than […]
