lipid bilayer. It has different receptors that allow different ions to pass‚ depending on the conditions in the cell. Leak channels- always open allow ions to flow back and fourth across the cell membrane Na cl ‚K and Ca ions and they just flow back and fourth without any gate keeper or obstruction‚ When the neuron is at rest its cytoplasm is Negatively charged. That means that it is not going under depolarization‚ we use the term resting potential. Modality gated channels- specific to sensory

Bradbury’s Predictions of the Future “Sometimes writers write about a world that does not yet exist. We do it for a hundred reasons. (Because it’s good to look forward‚ not back. Because we need to illuminate a path we hope or we fear humanity will take. Because the world of the future seems more enticing or more interesting than the world of today. Because we need to warn you. To encourage. To examine. To imagine.) The reasons for writing about the day after tomorrow‚ and all the tomorrows that

VI. Results and Discussion In this exercise‚ the goal was to produce acetylsalicylic acid through the organic synthesis from the reaction of salicylic acid to acetic anhydride‚ the starting materials. Instead of using acetic acid‚ acetic anhydride was used as solvent since the anhydride reacting with water to form acetic acid tends to drive the reaction to the right. It results from the elimination of a molecule of water from two molecules of acetic acid (see Fig. 11.2). Figure 11.3 below

patterns can influence natural ecosystems‚ dependency of cultures and global economy. The phrase “regardless of the cause” states that climate change can be induced by human activity as well as natural causes. This issue is largely debated over the world and the controversial idea of whether humans are causing increasing climate change. Many predictions have been made to expect the effects and the extents of climate change. Global Climate change will firstly increase the earth’s average temperature. This

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
