    I always used to say ‘yes’. My mother never taught me how to say ‘no’. That’s why I am in a corner crying. Not crying‚ crying is too little of a word. I am sobbing. Heart retching sobs that make my body convulse and make me shake uncontrollably. That’s why in my head I am repeating over and over things that make me feel only inches tall. Why did you just take it? Why didn’t you stop him? You’re to blame you didn’t say no! You didn’t stand up for yourself! I am in the corner of my new room in the

    1. a. The action potential changes the membrane potential from -70 mV (resting) to +30 mV and back again to the resting membrane potential. b. This results from a change in membrane permeability first to Na then to K due to the opening of what type of ion channels? Voltage gated channels 2. a. Where is the density of voltage-gated Na+ channels the greatest? Axon hillock b. What areas of the neuron generate signals that open these voltage-gated channels? Dendrites and the cell body c.

    system between two countries‚ we want to see differences (there are similarities as well but we more focus on the differences). However‚ the way to solve each problem depends on all different educational culture‚ politics‚ society‚ economic situation. ‘WHY AND HOW THESE FACTORS MAKE THE DIFFERENCES OF EDUCATION’ have to be and can be asked to these external factors. Friedrich Schneider‚ called ‘a father of comparative education’ listed the factors that decide the characters of educational system.

    The Theory of Secularization is‚ by its very nature‚ complex and unintuitive. Secularization‚ boiled down‚ is “the passage‚ transfer‚ or relocations of persons‚ things‚ functions‚ meanings and so forth from their traditional location in the religious spheres to the secular spheres” (Casanova 13). In fact‚ the theory of secularization is so hard to study and perceive that many still wonder whether or not it is myth in practice (Casanova 11). In part it is so difficult to study because Secularization

    This molecular orbital model can be used to explain why He2 molecules don’t exist. Combining a pair of helium atoms with 1s2 electron configurations would produce a molecule with a pair of electrons in both the bonding and the * antibonding molecular orbitals. The total energy of an He2 molecule would be essentially the same as the energy of a pair of isolated helium atoms‚ and there would be nothing to hold the helium atoms together to form a molecule. The fact that an He2 molecule is neither

    fundamental unit of the nervous system. These neurons work together with other excitable cells to produce action potentials when they receive electrical or chemical stimuli. Action potentials can be thought of as an “all-or-nothing” event and occur as a large-scale depolarization when sodium and other positive ions rapidly enter the neuron through membrane channel proteins. Once initiated‚ action potentials travel down the length of the axon and when it reaches the end a neurotransmitter is released into
