Ashley Contreras English 910 Quan Chen 12/11/2012 Persuasive Essay Animal abuse is when someone inflicts pain or harm upon an animal such as not giving them their basic needs (food and water) to beating them. In between 5 and 7 million animal companions enter an animal shelter nationwide‚ every year (www.aspca.org)‚ and within 50 miles of Hayward‚ CA‚ there are 170 animal cruelty cases reported (www.pet-abuse.com). Imagine what these innocent beings that cannot speak out to let the human know

Activity of the Enzyme Catalase in breaking down Hydrogen Peroxide and the effect of various factors on Enzyme Activity Introduction The enzyme catalase is present in cells in order to speed the breakdown of hydrogen peroxide (H2O2)‚ which is a toxic chemical to the human body. When hydrogen peroxide is broken down‚ the end products are Water (H2O) and Oxygen (O2). In this report‚ the reaction of catalase to hydrogen peroxide is being tested. Furthermore‚ the effects of temperature‚ concentration

Affect of enzyme concentration to the rate of reaction Aim: With the experiment of protein solution‚ in this case egg white added to different pepsin concentrations (0%‚ 0.2%‚ 0.4%‚ 0.6%‚ 0.8%‚ 1.0%) shows‚ as the egg white is a protein and the pepsin works as an enzyme‚ how a higher pepsin concentration and therefore a larger amount of enzymes effect the rate of reaction. Hypothesis: An increased concentration of pepsin speeds up the time the mixture needs to come clear. Introduction:

Discussion The primary purpose of this experiment was to determine the optimum temperature range for the activity of the enzyme lactase. Extreme temperatures can have a detrimental effect on enzymes; very hot temperatures can cause the denaturation in the enzyme‚ which is the loss of protein structure. This causes a change in the shape of the enzyme leading to its inability to perform its function. As previously stated‚ the alternate hypothesis read: the optimal temperature range for lactase activity

The environmental factors that effected the rate of enzyme reactions were the enzyme concentration‚ pH‚ and temperature. These environmental factors help enzymes break down the poisonous chemicals into harmless substance. When we tested the liver with 2ml of hydrogen peroxide for a normal reaction it showed that it was exothermic. We added more hydrogen peroxide and the reaction rate of the liver was 3. We learned that the catalase is reusable because the liver reacted both times when we put in

Statement of Problem This experiment aims to measure the effect that distance eastward from a wall in the West High School baseball lot has on the number of dandelion stalks found in the field‚ sampled with belt transects. The wall runs parallel to a major street‚ so this measurement could also show the correlation between dandelion population and distance from the street. Hypothesis It was hypothesized that dandelion stalks would appear in greater numbers away (at least 4 meters away)

approach was to skip the intermediate level of influences and go directly to consumers. In this case‚ it works to sell Raja condoms directly to the market since it’s more like a one-time use consumer products. However‚ it’ll be difficult for Maya to build up the brand image since customers perceived Maya as a drug‚ which will bring more concerns when people try to buy oral contraceptives. Hence‚ it still needs recommendations from doctors to convey the effectiveness and proper information about the drug
