Neurophysiology of Nerve 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. If the extracellular K+ increases then the concentration of intracellular K+ will decrease causing a decrease in the steepness of the concentration gradient and fewer K+ ions would be drawn out. 2. Explain why increasing extracellular K+ causes the membrane potential to change to a less negative

Unlike most fairy tales‚ "Beauty and the Beast" has been a traditional tale where there are two paths to be developed in which Beauty faces challenges and the transformation that is sustained by Beast. Therefore‚ this shows how two opposing allegorical characters resolve their differences in joining wedlock. The version of "Beauty of the Beast" by Madame de Beaumont shows how Beauty ’s happiness is found on her abstract quality of good features. In this version‚ Madame de Beaumont not only stresses

Cardiovascular The cardiovascular system is consists of the heart and network of arteries‚ veins‚ and capillaries that transport blood throughout the body. There are two primary circulatory loops in the human body: the pulmonary circulation loop and the systemic circulation loop. The heart is a muscular organ about the size of a closed fist that functions as the body’s circulatory pump. It takes in deoxygenated blood through the veins and delivers it to the lungs for oxygenation before pumping it

Cardiovascular fitness is the practice of utilizing and transporting oxygen in the process using your heart lung and organs. The practice of this can improve the pumping of the blood and oxygen to the body making it more efficient and easier to release oxygen therefore improving your exercising techniques. An important fact about cardiovascular fitness is the maximum volume of oxygen you body can retain is VO2 Max. There are many forms of exercising and practicing cardiovascular fitness. Some examples

Once upon a time there was a frog who croaked away in Bingle Bog. Every night from dusk to dawn‚ he croaked on and on. Other little animals around loathed his voice but they were left with no choice. The crass cacophony; a very loud and unpleasant noise blared out from the sumac tree. At whose foot the frog sang till the break of dawn. The stones‚ prayers‚ sticks‚ insults‚ complaints and bricks could not silence the frog’s determination to display his heart’s great pride and joy. One
