Osmosis is the diffusion of a solvent across a selectively permeable membrane that occurs in response to differences in solute concentrations (Allen and Harper 2014).Osmosis can fall under the category of passive transport which does not require energy. With osmosis being a type of diffusion it is viewed as molecules moving from a high concentration to a low concentration. To further explain if there is a low water concentration‚ high amounts of solutes will be present. Water will most likely move

Four environmental factors of enzymes were tested in lab. The changing of pH‚ substrate concentrations‚ temperature‚ and an inhibitor (NaCl) and the effects it hade on the enzyme turnip peroxidase. Enzymes are biological catalysts which increase reaction rates by lowering the activation energies of substrates. A substrate is a reactant that interacts with the enzyme. The enzyme and substrate can be viewed as the recently discovered "induced fit model"‚ which suggests enzymes are flexible and dynamic

I am going to investigate how the resistance of the wire affects a current flowing through a wire. I know that as resistance changes‚ current changes‚ as Ohm’s law: I = V/R. If one part of an equation changes‚ the equal must be done to the opposite side. To detect how resistance affects current‚ I must first discover what factors affect resistance. These factors are: · Length of the wire if a wire is longer; there are more particles for electrons to move through‚ and therefore more resistance

But I think it happened because the blow dryer only focuses on one point so it doesn’t effect the other vanes. When I used the power of wind‚ I realized that the result was so much

"To See What Factors Affect The Decomposition Of Hydrogen Peroxide By The Enzyme Catalase Which Is Found In The Liver" Introduction: Enzymes are biological catalysts. They speed up the chemical reactions which go on inside living things. Without them the reactions would be so slow that life would grind to a halt. Enzymes work by when a substrate molecule bumps into a molecule of the right enzyme‚ it fits into a depression on the surface of the enzyme molecule. This depression is called the

A. 1What are the factors that affect the corn market (i.e. supply curve for corn production and demand curve for corn consumption) ? The corn market can be negatively affected because of the weather and climate have an impact on the supply of the corn. With a bad weather condition‚ like drought‚ the survivability of the corn decreases. The total corn produced the u.s. is facing a large deduce‚ most of the people will be affected. However the corn market can be positively affected. Firstly‚ if

CHEM 1112 Kinetics of the Persulfate – iodide Clock Reaction The purpose of this experiment is to determine the rate law and the activation energy for the reaction between persulfate ion‚ S2O82-‚ and iodide ion‚ I-: S2O82-(aq) + 2 I-(aq) 2 SO42-(aq) + I2(aq) The rate law can be written as Reaction rate = (1) Where m and n are the orders with respect to S2O82- and I-‚ respectively‚ and k is the rate constant. Determining the rate law involves determining the values
