Neurons‚ the Basic Elements of Behavior PSY 101 16 January 2011 One of the most basic yet complex systems in the universe is the biological organism‚ with even the simplest person being considered the most intricate and advanced biological entity alive. Each person’s actions are controlled by the brain‚ which when broken down to the simplest explanation is essentially the most advanced computer in the world and just like a standard home computer the brain is made up of several pieces to function

Polarization of the neuron’s membrane: cell membrane is surrounded by neurons as other cell has a membrane. If a nerve cell is not stimulated‚ the membrane is known to be polarized. For a neuron to be polarized‚ it is by maintaining excess of sodium ions on the outside of the cell and excess potassium ions on the inner part of the cell. A volume of sodium ions and potassium ions usually leaks through its channel but the sodium ions and potassium ions pumps on the membrane that restores the (k+) back

Ecotourism Ecotourism places a value on the health of the local people/tribes etc‚ animals/wildlife and environment and rather than aiming to earn a very high profit at all costs‚ it aims to earn a profit while respecting local people/tribes‚ animals/wildlife and nature as a whole allowing them to benefit in some way from the endeavor. Good ecotourism companies make conscious choices in every aspect of their business. For instance‚ they recycle products and choose biodegradable materials whenever

me is 9-11. That was crazy. On September 11‚ 2001‚ Osama Bin Laden was the stupid mastermind behind this attack. He had his men hijack 4 commercial planes‚ two of which crashed into the Twin Towers. The other two were planned for the Pentagon and the White House. They both failed for the Pentagon and White House. Some of the people on board of the plane put a stop to the hijackers and made them crash into a field. This event was the 3rd most important to me. It was important because this attack

Activity 1 Pre-Lab Quiz K+ inside a cell = 150 mM; K+ outside a cell = 5 mM Na+ inside a cell = 5 mM; Na+ outside a cell = 150 mM Stop & Think question What is the polarity of the resting membrane potential (voltage)? Negative What does it mean that the voltage just inside the membrane is negative? B Membrane of most cells contains K+ leak channels…..b What will happen to the resting membrane potential if the extracellular K+ concentration is increase? Less negative What happens
