INTRODUCTION OF ENZYMES Enzymes are complex proteins that cause a specific chemical change in all parts of the body (David C. Dugdale‚ 2011). When we understand enzymes we understand cells (Marshall Brian‚ 2001). In many organisms most chemical reactions are catalyzed -when a substance speeds up the rate of a chemical reaction- by enzymes. Each enzyme controls a certain function that happens in a cell. Still each one has its own process and rate that it converts molecules. Studying enzymes shows how chemical

Osmosis Lab Report The essential focus of the experiment was to acquire data for the mass change resulting from osmosis in order to determine the carbohydrate solution of the carrot cells. The carrots were a vegetable used within the experiment with a carbohydrate solution around .5 M. The hypothesis is if there are carrots in different carbohydrate solutions then there will be a percent change in mass. The carrots have large vacuoles that hold water‚ this allows the mass to increase when the hypertonic

Section November 7‚ 2012 Abstract The effect of water and fertilizer on corn seedlings was examined. It was hypothesized before the experiment that enough water with sunlight and air should make the plants grow healthy. It has to do with photosynthesis. Fertilizer is also going to make the plants grow much faster; this is because of the nutrients in it. The experiment took about four to six weeks to complete; it took some days for the seed to germinate before planting. The corn was growing there were

The Twin Experiments was conducted by Josef Mengele‚ during World War 2 in Auschwitz. Dr. Mengle was a medical researcher who was fascinated with twins in specific. From the three thousand children that would be pulled from the masses of people upon arriving only about 200 survived. Age didn’t matter‚ yet most were children‚ and if they were really young their mother would be allowed to stay with them. The twins recieved "special" treatmeant as they were allowed to keep their hair and clothes. A

Hawthorne Experiment. Advantages: During the experiment the performance of the group has increased (Not because of improving conditions‚ but because of the communication and collaboration) Disadvantages: there were personnel changes‚ that is the workers hostile watching the situation changed for those who would like to work in such conditions (that is attended only those workers who are more willing‚ not all workers) Conclusion: This experiment showed that workers are willing to actively

The singular deviation during this experiment was that we did not centrifuge the tube (for 5-10 seconds) after incubation. The mitochondrial DNA was amplified in sterile 0.5 ml PCR tubes. The reaction in tube one contained‚ 2 µl of our genomic DNA‚ 1 µl JOSH01 (a 10 µM forward primer) and 1

Inquiry Method Steps 1. Ask a question or identify the problem – What do you want to learn about? This question forms the starting point for inquiry. Example: You may be interested in discovering what methods of studying lead to better exam results. 2. Develop a hypothesis – A hypothesis is possible answer to your research question. Your hypothesis gives you direction. It helps you to determine what needs to be tested and which research method you will use. Example: You may hypothesize that
