What are microfilaments? (He said know how to identify/draw these) Note: since it is multiple choice‚ I doubt we will have to know how to draw them. **There are also short essay questions and‚ in past classes‚ he has asked students to draw. I thought the final was ALL MULTIPLE CHOICE???********************************

FACTORS AFFECTING SOLUBILITY There are three main factors that control solubility of a solute. (1) Temperature (2) Nature of solute or solvent (3) Pressure EFFECT OF TEMPERATURE Generally in many cases solubility increases with the rise in temperature and decreases with the fall of temperature but it is not necessary in all cases. However we must follow two behaviours: In endothermic process‚ solubility increases with the increase in temperature and vice versa. For

Factors Affecting Diffusion How does temperature affect diffusion? What is Diffusion? Definition 1: Diffusion is a process where by molecules move from an area of high concentration area to an area of low concentration. Definition 2: Diffusion is an evidence for moving particles. The spreading out of a gas is called diffusion and it takes place in haphazard and random way. Gases diffuse because the particles collide with other particles and bounce of in all directions. For example when

cCELL PHONES A cell phone is the biggest invention of this century. It changed our lives dramatically and nothing is the same anymore. Especially combining computer and phone made such a different world for everyone. The reason for the invention was to help us communicating easily‚ but in my opinion it also causes us to cut off communication between people. First of all‚ we became virtual humans because we are constantly texting and using social media on our phones‚ we also start having virtual

Chemistry Essay: Electrochemical Cells By John Williams An electrochemical cell is s cell in which chemical energy in a redox reaction is converted to electrical energy. It consists of two half cells connected internally by a salt bridge and externally by wires. A hydrogen half cell is the standard electrode and all comparisons of the other half cells are made against this half cell which has an E( value of zero volts. The E( values of other half cells are obtained by measuring the total emf (electromotive

Low Voltage Effects on AC Motors A drop in voltage will result in a proportionate increase in current. If the current exceeds the nameplate rating and is not corrected‚ this can result in damage to the motor from overheating Nameplate Rating An electric motor will have a nameplate rating for both voltage and amperage. When a load is on a motor‚ the motor must draw a fixed amount of power. The required power is about equal to volts times amps. Should the voltage fall below the nameplate rating

The effect of enzyme concentration‚ substrate concentration‚ pH‚ and temperature on the enzyme catalase. Introduction: Enzymes are biological catalysts; proteins and RNA. They are required for most biological reactions and they are highly specific. Each enzyme has an active site. The active site is the spot on the enzyme where a substrate fits in. Substrates binds with enzymes through the active site. Enzymes‚ being highly specific‚ only fit with one certain substrate. Enzymes and substrates
