Unknown Lab Report Microbiology Unknown A Sonia Kabra November 26‚ 2014 Introduction There are numerous reasons for identifying unknown bacteria. Some of these organisms have distinct qualities that set them apart from one another‚ such as the exposure to certain environments. Through out the semester in the laboratory‚ we are able to encounter some of the few microorganisms that we as humans have come into contact with. With the knowledge gained from the sessions in the laboratory‚ we can now

Abstract For this experiment we tested the effects of different adrenalin concentrations (0.001%; 0.01%; 0.1%) on the daphnia flea. The daphnia was placed on a slide with cover slip in order to examine its heartbeat by using the microscope. Aim In this Lab we will study the effect of different concentrations of adrenalin on the heart rate daphnia‚ the water flea. It is expected to recognize a threshold of the daphnia in its reaction the three different adrenalin concentrations‚ in terms of heart

Effect of pH on Enzyme Activity Athenaa Jeyachandran Mr.Menes Course Code January 21st‚ 2013 The Effect on Enzyme Activity Due to Temperatures Purpose: The purpose of this lab experiment is to examine how different temperatures affect enzyme activity using hydrogen peroxide. Hypothesis: My hypothesis for this experiment is that temperatures near body temperature is when enzyme activity will be at its highest. I believe this will occur because in our body‚ enzymes

Correlation between the chemical activity of Amylase and change in temperature ABSTRACT This experiment focuses on how the change of temperature affects the rate of reaction of amylase. In the experiment there were four different environments that each contained 2 test tubes. Each test tube consisted of the same concentration and amount of starch and amylase. After having each test tube placed in these environments for several minutes a droplets of each mixture was placed onto each slot which

ABSTRACT. In this experiment‚ we test factors which affect friction. We pulled a wood block across a surface to determine whetherthe surface area ofthe block orthe type ofsurface affectsfriction. We found that the surface area of the block did not change the coefficient of kinetic friction‚ while the types of materialsin contact were directly related to the coefficient of kinetic friction. INTRODUCTION Friction is a part of our everyday life. Nearly every movement we make involves friction

Enzyme Lab Report Introduction: Enzymes are proteins that enable chemical reactions. In the enzyme lab‚ the effects of concentration‚ temperature and pH on the functionality of the enzyme catalase. The enzyme lab was also about measuring reactions by capturing the oxygen that was generated by the reaction. Materials and Methods: Experiment 1‚ 2‚ & 3 Experiment 1 examined the effects of concentration on catalase activity. Experiment 2 examined the effects of concentration in temperature on catalase

Nervous System lab was designed to measure reaction times by using a variety of tests that affect the heart rate. These tests were the startle‚ stroop‚ Valsalva maneuver‚ diving reflex‚ and a test of our choice. The test our group chose to measure the heart rate in response to doing a trust fall to anticipate the stress right before the fall. To begin this lab we chose a participant‚ and then hooked their finger up to the pulse transducer sensor. Using the chart 5 program on the lab computer the participant’s
