Being a couch potato is what many of us tend to be when we are on a break or on a holiday but why not try to do something different and useful that could bring benefits to one’s self? Earning additional cash over the internet could be let us just say one of the most beneficial way to kill time. Making extra cash is not easy but it is definitely worth the effort because the extra cash could come in handy during the rainy days. Besides‚ it’s easier earning some side income through the internet than

experiment shows the effects of changing the pH level has on Catalase. As predicted‚ the farther away the pH levels got from the optimum pH (7.2)‚ the lower the reaction rate. At a pH of 7.2‚ the foam of the reaction measures 6cm. At a ph of 3 it measures 2.5 cm‚ at a pH of 5 it measures 2.75 cm‚ at ph 9 it measures 2.3 and at 11cm it measures 2cm. pH measures the hydrogen ion concentration of a substrate. By changing the pH of the catalase‚ the enzyme was denatured. Denaturing is the result of altering

Bigger‚ Faster‚ Stronger By the phase “American as apple pie” I believe they are comparing it to be as normal as eating a peace as apple pie. The reason for this is because the use of steroids has become so common in the United States that even students in high schools are consuming them to increase there body mass. I do agree with this statement because it is true almost every house hold that someone would come across in the United States would most likely have steroids in there possession

land of Bangladesh. In last few decades‚ the demand of potato is increasing rapidly. As a developing country‚ the people of Bangladesh are not so affluent. That’s why they prefer potato to rice or wheat. The demand of potato is thus increasing as it is cheaper than the other two horticultural product rice and wheat. Last year‚ the production of potato is massive. But‚ that huge production makes a little impact on the price level of potato. The price at the point of production is relevantly low

the bacterium was a gram negative or a gram positive. After performing the gram stain‚ I concluded that by the appearance of purple spherical clusters resembling grapes that is was a gram positive cocci. A Catalase test was then performed using hydrogen peroxide. A positive catalase test was observed when bubbles started to form on the culture distinguishing Staphylococcus spp. form on the culture distinguishing Staphylococcus spp. from Streptococcus spp. Finally‚ a Mannitol Salt Agar

Refraction: Does light travel faster in water or air? A straight stick appears bent when partially immersed in water; the sun appears oval rather than round when it is about to set; a stream may appear to be much shallower than you know it to be. These are some of the effects caused by the refraction of light as it passes at an angle from one medium to another. Light refraction happens every day in almost every little thing‚ it is an optical illusion. For our science fair project my

trend O2 production and reaction velocity increased with increasing catalase concentration‚ however‚ the 33% percent catalase concentration showed a drop of 0.175 mL O2/s compared to the 25% catalase concentration (figure 1.2). The velocity of 25% catalase was 0.275 mL/s‚ 33% was 0.1 mL/s‚ 50% was 0.435 mL/s‚ and 75% catalase was 0.575 mL/s (figure 1.1). The 50% catalase concentration produced the most O2 overall however the 75% catalase concentration had the fastest initial reaction velocity. Experiment

Testing Catalase Activity Prepared by Anel Behric For professor Goodrow General Biology Lab Mohawk Valley Community College 10/14/2014 6:00 PM Introduction: This experiment was conducted to examine the breakdown of substrate hydrogen peroxide (H2O2) by catalase‚ which is a specific enzyme that breaks down substrates of (H2O2). Molecules are in our bodies and nature. They move around constantly which causes them to be part of random collisions‚

Keegan Bauman Potato Lab Dr. Peano Block 1 Introduction: Potatoes are just your average food; they have been around for as long as the human race can remember. In this lab we will make them be a prime example of osmosis‚ which is a transport mechanism. In this lab the problem being tested was what environment affects the mass of the potatoes the most. The independent variable is the environments used salt‚ water and iodine solution. The dependent variable is the mass of the potato after being

Potato Cell Cytoplasm Composition PURPOSE: To determine the concentration of salt in the cytoplasm of potato cells HYPOTHESIS: Increase in salt concentration results in a hypotonic solution where the mass of the potato increases due to the movement of water into the cell. On the other hand‚ decrease in salt concentration results in a hypertonic solution where the mass of the potato decreases due to the movement of water outside the cell.
