Homeostasis Lab: The Effects of Exercise on Homeostasis Purpose: To discover the effect that various levels of exercise have on specific body parameters. Hypothesis: If a subject walks up and down a flight of stairs for eight minutes‚ then they start to sweat more‚ their heart rate‚ body temperature‚ and breathing rate will increase‚ and there will be a change in their skin color on their arms and face‚ because the body will be trying to maintain homeostasis. Materials: You will

INTRODUCTION There are many reasons for knowing the identity of microorganisms. The reasons range from the knowing the causative agent of a disease to knowing the correct microorganism in order to make antibiotics. This study was done by applying the following methods; OF Glucose‚ Indole Production‚ and Malonate Utilization test for the identification of an unknown bacterium. The methods will assist in determining the unknown bacterium found in a 55 year old male that was passing blood and mucous

The objective of the deicer lab was to successfully conduct experiments to determine the usefulness of magnesium chloride as a deicer. To find how successful magnesium chloride is as a deicer‚ experiments were conducted to determine the freezing point depression‚ enthalpy of dissolution‚ the impact on the surrounding environment‚ and also the expenses of using magnesium chloride as a deicer. For magnesium chloride to be determined as a good deicer‚ the reaction with water needs to be exothermic so

The purpose of this experiment is to study how enzyme activity is affected by environmental conditions. Researchers tested the level of potato extract enzyme activity with 1-11 pH‚ varying temperature‚ catechol solution‚ hydroquinone solution‚ and different measurements of catechol. In Figure 1A and 1B‚ pH levels were tested with potato extract to see how pH would affect the amount of Benzoquinone is formed in the potato. Although it was hypothesized that enzymes would form Benzoquinone better in

Hoeung 1 Tiffany Hoeung Ms. Braceras Honors Earth Science 4 March 2015 How Does Slope Affect the Movement of a Glacier Purpose: The purpose of this lab was to find how slope would affect glacier’s movement‚ and whether the movement was at a constant rate or changed. Hypothesis: If the slope is more steep‚ then the glacier’s movements will be faster than a less steep slope. Materials: Flubber Glue Water Borax Long tray Timer Procedure: 1

Effects of Temperature on the Formation of Cheese Curds This lab was performed in order to find what temperature the enzyme chymosin is most effective at forming cheese curds. An enzyme is a protein that acts as a catalyst to speed up biological reactions in cells. They work by lowering the activation energy and help to orient the molecules correctly. Chymosin was originally taken from the stomachs of calves‚ and was called rennet‚ and then purified to make rennin. Eventually to catch up with

When a specific substrate binds to the active site of an enzyme‚ the active site undergoes slight conformational change to keep the substrate long enough to be converted to a product. So‚ the activity of enzymes can be determined by measuring the number

OF VARIOUS METALS. THE MAIN OBJECTIVES OF THIS LABORATORY ACTIVITY ARE TO DETERMINE THE SPECIFIC HEAT OF METALS AND TO COMPARE THE EXPERIMENTAL RESULT OF SPECIFIC HEAT FROM THE STANDARD VALUE. ANOTHER PURPOSE OF THIS EXPERIMENT IS TO DETERMINE THE RELATIONSHIP BETWEEN THE SPECIFIC HEAT OF THE MATERIAL AND THE CHANGE IN TEMPERATURE. LASTLY‚ IS TO IDENTIFY THE FACTORS NEEDED TO CHANGE THE TEMPERATURE OF THE SUBSTANCE. AT THE END OF THE ACTIVITY ALL OF THESE OBJECTIVES WERE MET. INTRODUCTION
