Purpose: The purpose of this lab was to see how the changes in exercise intensity affect the rate of metabolism within the body. Methods: In this lab‚ indirect calorimetry was used to measure metabolic rate by calculating caloric expenditure by the measurements of oxygen consumption. The variables measured were the fraction of oxygen expired‚ the fraction of carbon dioxide expired‚ and the total volume of air inspired. This experiment required the participation of two volunteers. First‚ the variables

component‚ and so on‚ until it reaches the source again. In contrast‚ a parallel circuit is a circuit in which the has more than one resistor and has multiple paths to move along. The main purpose of this lab was to prove the laws of Ohm and Kirchhoff. On another note‚ being able to take part in this lab taught my partner and I the fundamental skills of constructing series and parallel circuit and using a multimeter to calculate the current and voltage of a circuit. I believe that if we only have the

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

Biology Laboratory Report MEASURING RATE OF WATER UPTAKE BY A PLANT SHOOT USING A POTOMETER Introduction All plants need salts minerals‚ water‚ CO2 and O2. To fulfill their requirements different plants use different ways. Lower plants use diffusion‚ however higher plants use vascular tissue that is located in the middle of the root and in the vascular bundles in the stem. The transpiration is the important process in the plant. The main reason is that transportation

Osmosis Lab: The Incredible Egg How does the solution a cell is in effect the movement of substances into and out of the cell? Eggs were soaked in vinegar for twenty-four hours before the lab to dissolve the shell‚ then placed them into the distilled water. Then the eggs were taken out and dried by the paper towel to measure their weight on the electronic scale. First egg weighted 78.92g‚ most of the parts of it’s skin was white translucent‚ and was spongy. After the egg was submerged into the

Unknown Lab Report Dr. Nathan Cahoone Microbiology 204 December 9‚ 2010 Introduction There are many reasons for knowing the identity of microorganisms. The study and test was done by applying all of the methods that have been learned so far in the microbiology laboratory class for the identification of an unknown bacterium which I was using unknown #25. Results Unknown #25 had the following morphology on a streak plate: medium sized butyrous cream colored colony. Gram-staining was utilized

Experiment 13 Charging and Discharging Capacitors 1. Introduction In this experiment you will measure the rates at which capacitors in series with resistors can be charged and discharged. The time constant RC will be found. Charging a capacitor. Consider the series circuit shown in Fig. 1. Let us assume that the capacitor is initially uncharged. When the switch S is open there is of course no current. If the switch is closed at t=0‚ charges begin to flow and an ammeter will be able

Purpose The purpose of the “Beanium” lab was to determine the average atomic mass of three different isotopes of beanium. During the lab beans were counted to determine mass of the sum of the beans. Each type of bean were weighed separately and then averaged together to determine the average atomic mass of beanium.
