The Nervous System: Ion Channels 1. What structures in the cell membrane function as ion channels? Intergral Proteins 2. Ion channels are selective for specific ions. What three characteristics of the ions are important for this selectivity? a. Charge on ion (+ or -) b.Size c. The amount of water the Ion attracts 3. Channels can be classified as either gated or nongated channels. A sodium channel that is always open would be classified as a/an non-gated channel. 4. Would

Attempting to create a diagram of the ecological cycle of copper must require knowledge about copper’s chemical cycle first‚ which may then allow for the development of possible solutions to copper pollution.

Investigating Specific Environments Abstract: The thing that I did was analyze soil to see if bacteria could live in that environment. The reason why I did it was because I wanted to find out where in the environment bacteria and fungi can live. In order to do my study I had to collect a sample of soil and put it in a dish. After I did that I could look at it underneath a microscope. I found that bacteria did in fact live in the soil so the soil was a sustainable environment for the bacteria

from flows of electrons between the two metals in the metal sulfate solution of the electrolyte. In order for a chemical reaction to take place‚ the reactants must collide. The collision between the molecules in a chemical reaction provides the kinetic energy needed to break the necessary bonds so that new bonds can be formed. Thus‚ increasing the concentration of the anode‚ zinc sulfate‚ will increases the rate of reaction for oxidation because there are more zinc ions in the new concentration

We will also describe what is occurring with the molecules on a molecular level. Lastly we will explain what chemical bonds are formed and or broken when lemon juice and backing soda. Observations of the Reactants When most people hear baking soda they think of the bright orange box sitting in their pantry or refrigerator soaking up the foul odors

the most abundant thing in the universe? Hydrogen is the answer! Now with a little bit more refining it will be. Good morning fellow students today I will be talking about hydrogen powered vehicles. Firstly‚ some terms need definition.Hydrogen- a colourless‚ odourless‚ flammable gas which is the lightest and simplest of all known elements.Vehicle- A device or structure for transporting persons or things. Secondly‚ now to explain the ways to use hydrogen as a fuel. The first way is called electrolysis

Chemistry 2500- Exercise C4 The Emission Spectrum of Atomic Hydrogen Objective The purpose of this lab was to calculate an experimental value for the Rydberg constant and then the ionization energy for the hydrogen atom. These values will be obtained by using a prism spectrograph to measure the wavelength value for a section of the visible line spectrum of atomic hydrogen. Theoretical Background When H+ combines with an electron it forms it’s excited state‚ H. This excited atom
