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

Which amendment do I believe is most important? There comes a moment in your life when you decide to grow up. For me that took place heading into my freshmen year of college. I was 916 miles away from home‚ in a little town in Nebraska called Crete. Crete had a total population of 10‚000 residents and compared to San Antonio where I was from the way of living and attitude was different there. I didn’t forget what my parents taught me however I did develop a different way of thinking and had so much

Summary According to Kelso and kugelmas (1997)‚ abdominal pain is one of the most common reasons why people seek medical care. Due to the diversity of the signs and symptoms of acute abdominal pain‚ nurses in different levels who are involved in the initial assessment and treatment of these patients are required to follow a systematic

Cell Membrane Structure Phospholipids are arranged in to layers‚ called the bilayer. They only have 2 fatty acids‚ this is because the third fatty acid is replaced by a negatively charged phosphate group. The phosphate heads are polar‚ in other words attracted to water‚ therefore they are hydrophilic. The lipid tails are non-popular as they’re not attracted to water and therefore known as hydrophobic. When phospholipids are added to the water‚ they rearrange themselves so that the hydrophilic heads

Practical 2.1- The Effect of Temperature on Membranes Objective To investigate the effect of temperature on membrane structure Introduction Beetroot Pigments Beetroots contain Betalains which are the red pigments present in the cell vacuole. Betalains are soluble in water and they contain nitrogen. Betalains extracted from beetroot is commonly used as food dye because it is not known to cause any allergic reactions.

6. What do you see as the most likely future(s) of diplomacy? Will this (these) be the same in every sphere of policy? And in all parts of the world? In today’s world the concept of "diplomacy" over the years is beginning to take many faces. After World War II‚ the concept of "world order" was as clearly delineated‚ as the concept of "diplomacy". But over time‚ diplomacy ceased to be a binding chain between states. It has expanded its scope of action. Along with public diplomacy began to appear more
