INTRODUCTION Philippines are known for its beautiful scenery and friendly people‚ it is known as well for its delicious food. Among these foods is what we called “kakanin”‚ a native delicacy that are serves as desserts. Parties and celebrations seem not perfect without these Filipino desserts. What is more interesting about them is that they vary from one area to another in terms of ingredients. Another thing is that a lot of Filipino or the senior citizens know how to to make desserts as they

During the 18th century‚ intellectual changes began to dismantle traditional values and institutions. Liberal ideas from France and Britain spread rapidly‚ and from 1789 the French Revolution became the genesis of "liberal Italians". A series of political and military events resulted in a unified kingdom of Italy in 1861. The settlements reached in 1815 at the Vienna Congress had restored Austrian domination over the Italian peninsula but had left Italy completely fragmented . The Congress had divided

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

Action Potentials An action potential is the change in electrical potential associated with the passage of an impulse along the membrane of a muscle cell or nerve cell. An action potential occurs when a neuron sends information down an axon‚ away from the cell body. A threshold is the minimum amount of stimulation needed to start a neural impulse (you know‚ the electrical impulses that travel throughout your body carrying important information). Action potentials generated by neural impulses are

that it is not going under depolarization‚ we use the term resting potential. Modality gated channels- specific to sensory neurons‚ open in response to mechanical forces (i.e. stretch‚ touch‚ pressure‚ temperature changes or chemicals) Ligand- is a particular molecule that causes a receptor to open. The ligand gated channels open in response to a neurotransmitter binding to the surface of a channel receptor on a postsynaptic cell membrane‚ when open these channels allow the flow of electrically

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
