    It was just a normal night in the neighborhood‚ street lights on and all was good. Every night my wife and I sit in our living room and watch TV or just talk and look outside. There was very light traffic‚ I had only seen 2 or 3 cars that night. After a while we noticed that Rhoda had pulled into her driveway pretty late. I had forgotten to get my mail that day so I went out to the mailbox and waved to her. I went back inside and was going to get ready for bed. I took a quick shower and got my pajamas

    action potential

    The formation of an action potential can be divided into five steps. (1) A stimulus from a sensory cell or another neuron causes the target cell to depolarize toward the threshold potential. (2) If the threshold of excitation is reached‚ all Na+ channels open and the membrane depolarizes. (3) At the peak action potential‚ K+ channels open and K+ begins to leave the cell. At the same time‚ Na+ channels close. (4) The membrane becomes hyperpolarized as K+ ions continue to leave the cell. The

    III. HYPOTHESIS The researchers suggests that students should have less time in using their gadgets‚ especially their cellular phones‚ iPods‚ PSPs‚ Laptops‚ and their own personal computers. Why the researchers included personal computers? Because most of the time‚ students nowadays use their personal computers for gaming and entertainment purposes. The researchers formulated this as a possible solution because if the students lessen their time on their gadgets‚ then they will have more time

    THE WORK DONE BY A CONSERVATIVE FORCE ALWAYS HAS FOUR PROPERTIES: 1. It can be expressed as the difference between the initial and final values of a potential-energy function. 3. It is independent of the path of the body and depends only on the starting and ending points. 2. It is reversible. 4. When the starting and ending points are the same‚ the total work is zero. The total mechanical energy ME = K + U is constant. Object moving in a uniform gravitational field gravitational a

    which cell has the larger resting membrane potential? Explain. If the permeability to K is higher in A than in B‚ then the resting membrane potential (rmp) will be closer to the equilibrium potential in cell A‚ which means the rmp will be more negative in cell A than in cell B; or in other words‚ the potential difference will be LARGER in cell A. 2. Predict the effect of a reduced extracellular concentration of Na+ on the magnitude of the action potential in an electrically excitable cell. If there

    Potential Energy • Definition and Mathematics of Work • Calculating the Amount of Work Done by Forces • Potential Energy • Kinetic Energy • Mechanical Energy • Power An object can store energy as the result of its position. For example‚ the heavy ball of a demolition machine is storing energy when it is held at an elevated position. This stored energy of position is referred to as potential energy. Similarly‚ a drawn bow is able to store energy as the result of its position. When assuming
