Based on the prompt above‚ “You are going to test your body’s ability to maintain homeostasis. You will test this by monitoring a person in your group’s breathing rate‚ heart rate‚ and qualitative observations” we devised a hypothesis which states that if a person exercises‚ his/her heart rate‚ breathing rate and sweat (qualitative observation) will increase in order for our bodies to maintain homeostasis and control our bodily functions. Based on our experiment we found that in Trial 1 the heart

Ph Lab Report Bryon Kim 123013 B(2) Biology Background information/Research PH paper (litmus paper) determines how acidic or how basic a substance is. The paper changes color accordingly to color code on the pH scale. The pH scale starts from 0 to 14. The lower the number the more acidic it is. Zero is the most acidic‚ and 14 is the most basic while 7 is the neutral number for example water. Examples of an acid is lemon juice or multi purpose cleaner. Examples of a basic substance is shampoo or liquid soap

Introduction The purpose of this lab was to identify unknown bacteria cultures using various differential tests‚ and my unknown bacteria is #17. The identification of these unknown cultures was accomplished by separating and differentiating possible bacteria based on specific biochemical characteristics. Whether the tests performed identified specific enzymatic reactions or metabolic pathways‚ each was used in a way to help recognize those specifics and identify the unknown cultures. The differential

University of Texas at Tyler Lab 3C: Purification of L-Lactate Dehydrogenase By Affinity Chromatography on Cibacron-Blue Sepharose David Alexander 10-15-2014 Dr. Black Chem 4135.001 Abstract: Like the previous experiments‚ the ultimate goal of this lab was to purify the enzyme sample. However‚ this is the last lab for purification and high level techniques of purification were employed to achieve this. Dialysis was used first‚ lowering the small-molecule concentration within the sample. Finally

because the fan cart gives off a constant force. The result that we got for work in the four trials is increasing from the first trial to the last trial because we increases the distance it covers and the work is the product of the force and the distance covered by the object. And the power is the rate at which the work is done it is the work done per unit of time which is second. We got the values of power by dividing the work by the time we got in the smart timer reading. And in table 2‚ we measure

One toothpick broken into two pieces equals one reaction. Broken toothpicks cannot react again. (Toothpicks can only be broken once) The toothpicks are broken between the thumb‚ index‚ and middle finger (toothpickase). Break two toothpicks at a time (Trail 3). Tape the index finger and thumb.

However‚ when subject exercise the heart rate increase‚ because the muscles need more oxygen to produce energy. In the other hand‚ inhalation (23.18) increased heart rate than exhalation (15.87). This can be concluded‚ because blood going to the heart increased (increase in heart rate. As a result‚ the heart rate increase when the body is in intense movements
