. Na+ and K+. K+ was more concentrated inside the cell while Na+ was more concentrated outside the cell. 2. A cell is at rest without any implications of changing the potential. 3. 4. 5. K+ is more permeable than Na+ in a resting neuron. This is because there are few sodium leakage channels. 6. Since the resting membrane potential is the potential difference between the inside and outside of the cell across the membrane‚ a change would depend on the resting permeability of the membrane to ions.

Title: Lab #3 Separation of a Mixture of Solids Purpose: To understand the different separation methods and techniques that depend on the chemical properties of a specific substance. Also to become more comfortable with performing those actions of separation so I have them in the future. For this experiment‚ I will separate a mixture of four distinct substances: sodium chloride‚ benzoic acid‚ silicon dioxide‚ and iron fillings into pure beings. Procedure: Materials: distilled water coffee

Advantage Transport System 1. What should the company do about the new business contract? ATS should take advantage of the new business opportunity that Alec discussed. If ATS gets the contract with the large domestic auto manufacturer‚ that would not only increase their revenue but ultimately open the door for other opportunities. ATS should also see where the company can make adjustments in pricing and offer special promotions for their current customers. After careful review of recent loss

≪Propose a reaction mechanism using the criteria presented in the lesson‚ with the third step as the rate-determining step. Hypothetical reaction: A + 2B + 4C ---> 2D + E The rate law has been determined to be [B]^1[C]^2≫ I had prepared the material below before I received your criteria. As you know‚ each step in a reaction mechanism is an elementary step. Each step is characterized by its molecularity. A step could be unimolecular‚ as in A → B or A → B + C It could be bimolecular as in 2A → B +

1. The first Skills Lab was designed in order to introduce us to the course‚ prepare us for working in teams‚ and for preparing us for success in this course and our future engineering courses. During this lab we were able to see the importance of teamwork in engineering and learn the names of those we will be working with in this course. We discussed the norms of being on a team and how we must work together to complete our goals. Along with how we must work together in teams we learned how to avoid

Heather Crall Chemistry 1 SMT- 271044 10/17/2012 Abstract From seeing all of my results and conclusion I now see that I didn’t understand this lab very well and that its not easy when others try to help. Since I have hard water it tells me that my water flows over and through rocks and minerals‚ like limestone. Purpose The purpose of this lab is to become familiar with the concept of water hardness. We learn that hard water contains high levels of dissolved minerals that are in the form

Sebastian Krug‚ s082349 New Economy Transport 1 1 NET (A) - Question 1 As you can see on the rst spreadsheet the NPV of the overhaul with the new engine and control system (1:117:413; 38 Euro) is higher than the NPV without the new stu (480:211; 75 Euro). In this case Mr. Handy should choose the overhaul with the new stu . First of all the entire calculation is in real numbers. I’ve done it in nominal numbers too (with the same results) but it was too much to hand in. The assumptions I’ve
