John Leone Lab Partner(s) Ethan Davis & Ryan Hanna Date: 12/10/14 Instructor: Dr. Chuckran Period: H Plants and Animal Cells Abstract: In this lab‚ you will find out how plant and animal cells are alike and how they are different. The onion elodea cells were both plants‚ so they had a cell wall. The cheek cells were animal cells‚ so they did not have a cell wall. Eukaryotic cells contain structures called organelles that carry out life processes. Eukaryotic cells can be classified by the types of organelles they contain

IB Friction Lab Write Up 3. The slope of my graph represents the constant value for myu as the Normal Force and the force of friction are constantly changing. 4. The kinetic slope is the biggest by far because it represents the less coefficient of friction it has to overcome to move easier. 5. According to my data table‚ an increase in weight always‚ without fail‚ creates a greater force of friction. 6. An increase in weight does not affect the coefficient of friction by also increasing

Vaishnavi Kothapalli Mrs. Manning Honors Biology 30 November 2012 TITLE: The Reaction Rate of Catalase in Various Concentrations of Hydrogen Peroxide QUESTION: How long does the catalase take to float to the top of a cup filled with different amounts of hydrogen peroxide concentration? PREDICTION: A prediction that can be made for this experiment is that the higher the concentration‚ the faster time it takes the catalase to react with the solution. As the concentration increases from

1P Paper Towel Absorbency Experiment Write-Up Purpose: The purpose of this experiment is to conduct a valid experiment‚ realize that the way I conduct an experiment influences the data‚ and I want to know which paper towel has the higher absorbency times. My hypothesis is that bounty will be the quicker picker upper Materials and Methods: As a class we chose that our control out of the brands provided (Bounty‚ Viva‚ Wal-Mart‚ and the School brand) would be the Schools brand of paper towel

Introduction Enzymes are proteins that are involved in all the chemical processes in living things. As they are made of proteins they are affected by pH and temperature. Enzymes are catalysts; they speed up chemical reactions without being changed themselves. Digestive enzymes speed up the breakdown of large food molecules into smaller ones so that the blood can absorb them. Enzymes turn a large starch molecule into thousands of tiny glucose molecules. Enzymes end in ’ase’. There are thousands of

technology. By all means these risks should be identified and managed correctly. According to me‚ the most important point she raised in her lecture‚ and which I completely agree with‚ is that anyone‚ even the most unaware on this matter‚ can get involved in it. A part of her job was to find ways to make people use IT at its full extent but what really makes it possible is that designers strive to make IT as much user friendly as possible. For example

The materials used in this lab were a preserved clam‚ a dissection pan‚ bent tip probe‚ scalpel‚ specimen bag‚ pins‚ gloves‚ tools‚ paper towels‚ goggles‚ ruler‚ lab coat‚ etc. In Miss Sido`s lab prep she went over the lab packet‚ taught us how to set up for dissection by getting only the certain tools needed‚ having paper towels in the pan‚ and she taught us how to properly clean up after dissection. She performed a lab dissection demo‚ where she showed us

During the interview‚ she stated honesty and integrity as her main core values. She discussed that a leader in any professional field should be transparent with their workers or colleagues because it is what allows issues to be discussed. Mrs. Ramirez particularly believes without integrity there cannot be work ethics. She has experienced problems were professionals hire student workers that do not have these qualities. For example‚ there was a time one of her student workers lied about working extra

Vioxx Decisions – Were They Ethical? In the late 1990s‚ a pharmaceutical company called Merck was a leader in this industry. The pharmaceutical industry required millions of dollars and great amounts of time to be invested in research and development. From 1995 to 2001‚ Merck was successful in releasing 13 major drugs into the market. One of these drugs was one that would treat rheumatoid arthritis. The drug‚ Vioxx‚ acquired the approval of the Food and Drug Administration (FDA) in May 2009 (Cavusgil

Photography Write-Up: Separation The camera I use has been rented from the ERC on a regular basis‚ and is a Canon 600D or 700D. The photo’s i’ve captured for this project were shot on the standard lens‚ with a variety of settings. I also often use a mini LED light with a daylight filter in order to create more depth in the shadows in my images‚ I usually place this somewhere away from the camera in order to create angled shadows instead of images being frontlit. To start this project‚ I experimented
