Lab Report Microbiology Introduction Bacteria can be found almost anywhere. For human life‚ some help us‚ some hurt us‚ and others are neutral. It is now known that good bacteria‚ or normal microflora‚ can reach 1014 microbial cells. This is far more than the 1013 cells that make up the human body (Tannock‚ 1995). The total number of bacteria on Earth is estimated to be around 4-6 x 1030 (Horner-Devine‚ 2004). It is important to know the extent of bacteria‚ how they live‚ and how they are

Genetics of Drosophila Lab Report: The test of heredity in fruit flies In my testings with breeding the fruit flies‚ I learned that the purpose of breeding them was to test how genetics pass from generation to generation‚ also known as heredity. We attempted to breed the flies and get them as close to a 9:3:3:1 ratio as possible. This would lead to an acceptable trait ratio. My hypothesis was that if we were to breed the flies in a stable environment‚ the most common fly (or the fly with the highest

The temperature of water was determined by a thermometer. 1 cm stripped ends of the wires was hooked into the input posts on the back of the impendence converter. Lab tutor module was started after. B. Baseline heart rate The top of the container was covered with foil and the animal was allowed to sit quietly for 10 min. The trace was examined by pressing start. After that the baseline or the controlled

Regulation of the cardiovascular system by examining changes in heart rate Prepared for Dr. Isabelle Lys Lecturer of SBI171 Anatomy &Physiology Charles Darwin University Summer Semester 2012-2013 Introduction Every day the human body is involved in various tasks which can alter a person’s heart rate. Some internal and external factors that contribute to changes in HR are thermo-regulatory changes‚ diurnal changes and sudden postural changes‚ which are among others

Name the four (4) gastric cells; for each cell type give the name and function for each the chemical substance(s) it secretes. A) Mucous cells- These cells secrete mucus‚ which protects the mucosa from the action of acid and digestive enzymes. B) Parietal cells- They secrete hydrochloric acid (HC) and intrinsic factor.

Equipment Calibration is defined as the act of adjusting and evaluating the precision and accuracy of measured equipment. It allows the user to get an accurate and precise reading of measurements to its actual true value. However‚ in order for the experiment to be effective is must consist of validity‚ reliability‚ and objectivity. Validity is defined as the ability of a test to measure what it claims to measure. Reliability is the consistency of test results and objectivity is defined as a test

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

For this lab‚ the expected outcomes are that when the heart rate and blood pressure are measured‚ both will increase when the heart has to pump against gravity‚ after exercise the heart rate will increase then return to normal‚ and as the subject inhales‚ it will be lower than when they exhale. Methods For this lab report‚ the laboratory manual (2009) was used for all labs. While completing lab five‚ electrodes were hooked up to the subject. After calibration for this lab‚
