closer the heart rate should be to the resting heart rate of the Daphnia. Possible errors that could have gone wrong are the duration given to allow for the absorption of the different concentration of salt solutions due to the limited time during the lab period and the distinguishing of the separate heart beats and the inaccuracy of a constant time being off by points of a

1. Introduction Microscopy is an essential technique not only in cell biology but natural science as a whole. We compared different types of microscopic techniques ‚ according to the specimen used and the scope of the experiment. Two specimens‚ stained and unstained‚ containing CHO cells‚ were prepared‚ examined and analyzed under the microscope using bright field (HF)‚ dark field (DF) and phase contrast (PH) settings. In addition‚ the four phases of cell division cycle were estimated.. Bright

UNKNOW BACTERIA LAB REPORT UNKNOWN 36 Introduction The purpose of this lab was to identify two unknown bacteria from a mixed culture. The reason for identification of unknown bacteria was to help students recognize different bacteria through different biochemical tests and characteristics. This is important in the medical field because identification of unknown bacteria can help treat a patient by knowing the contributing source of a disease. Also knowledge of different bacteria helped others

Amber McMillian May 26‚ 2009 Bacterial Vaginosis This is a vagina condition also referred to as Gardnerella Vaginitis that can produce vaginal discharge that is a result from an overgrowth of normal bacteria. This will cause a woman to have a vaginal discharge with a foul odor. It is not dangerous but it can cause bad symptoms. If any woman has this problem they should also be checked for more serious infections such as Chlamydia and Gonorrhea. The normal symptoms are excessive vagina discharge

Name: Nikia Martinez Class: Biology 240L L3-1201 Assignment: Electrocardiography Lab Report Due: April 3rd 2012 Professor: Dr. B. Schoffstall Introduction In a normal human being the heart correctly functions by the blood first entering through the right atrium from the superior and inferior vena cava. This blood flow continues through the right atrioventricular valve into the right ventricle. The right ventricle contracts forcing the pulmonary valve to open leading blood flow through the pulmonary

decrease in pH‚ more bacteria present‚ and an increase in absorbency. The results proved that fermentation occurred with three positive confirmatory results from the gas production‚ pH‚ and turbidity tests‚ while the Gram stain test acted as a negative confirmatory test. Introduction: The main goal of this experiment was to successfully ferment milk into a yogurt-like product called Kefir. The fermentation is accomplished with a symbiotic combination of different bacteria and yeasts. The main type
