BIOSC 048: Problem Set Questions 1. Given that cell A has significantly more nongated K+ channels than cell B‚ 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

In my opinion what makes you‚ you is your soul‚ and I think your soul is inside of you‚ more specifically in your DNA‚ in each and every cell of your body. Of course‚ the way we look has nothing to do with our true self. A lot of people think that if we change our look or brain then it won’t be us anymore. Me in the other hand‚ I don’t think that way. I think that we only have a brain because we live on a materialistic world and our bodies are material and that is why we have a hard time understanding

Victoria Hourigan What techniques does Hill use to create tension in ‘whistle and I’ll come to you’? The opening paragraph to the chapter immediately creates tension. This is done by the use of pathetic fallacy in that Hill describes the atmosphere with ‘gusts that blew’ and that during the night it ‘increased greatly in force’. This instantly creates an ominous surrounding as it conveys how isolated Arthur and the house are. Moreover‚ it foreshadows a sinister future for Arthur and spider

Are You Sure You Want to Pick That Up? According to some neurologists and researchers‚ society should be asking itself this question every time they answer a call or hold a cell phone up to their head. Nowadays‚ cell phones are becoming an essential tool for modern life‚ whether it is the businessperson whose phone keeps him connected to his office and clients or the teenager who has a cell phone for recreational purposes. Cell phones present their users with the opportunity to contact their

Term 3 Uniform Circular Motion When a body moves in a circular path with a constant speed‚ it is said to undergo uniform circular motion. Although the speed is constant‚ velocity is continually changing‚ since it is constantly changing its direction of motion. Centripetal V V ac ac Acceleration is directed towards the centre of the circle and is therefore called “centripetal acceleration.” ac =v^2r ac =v^2r If T is the time taken for one revolution then: V = 2πrT ac =v^2r

You are what you say The essay‚ " you are what you say " is written by Robin Lakoff‚ a Professor of Linguistics at University of California. She has explicated her view on how English language has functioned to revile and debase women‚ why women are thought to be juvenile‚ dependent and frivolous species. Certain views which makes fair sex less thriving than men. The subject is of great interest as it illustrates that women only say what they mean‚ but what they say is inferred by men in a pejorative

mosaic model of the cell membrane. What is the fluid mosaic model? The fluid mosaic model is a model conceived by S.J. Singer and Garth Nicolson in 1972 to describe the structural features of biological membranes. The membrane is described to be fluid because of its hydrophobic integral components such as lipids and membrane proteins that move laterally or sideways throughout the membrane. That means the membrane is not solid‚ but more like a ’fluid’. The membrane is depicted as mosaic because
