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

Urinalysis also called urine test. This test can help find conditions that may need treatment or detect some common disease‚ urine test help find serious diseases in early stages. It may take before surgery or people at high risk for kidney problems‚ diabetes‚ liver problems or any other metabolic conditions. Patients will be asked to pee in to a clean cup called specimen cup‚ urine test only require small amount of the urine. Usually they are two parts of urine test include. First part‚ visual

Separating Substances: Identifying Food Dyes with TLC Background The color of food is an integral part of our culture and enjoyment of life. Who would deny the mouth-watering appeal of a deep-pink strawberry ice cream on a hot summer’s day or a golden Thanksgiving turkey garnished with fresh green parsley? Even early civilizations such as the Romans recognized that people "eat with their eyes" as well as their palates. Saffron and other spices were often used to provide a rich yellow color

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

Carbohydrate Fermentation Testing Questions A. What is fermentation? It is a metabolic process that allows the production of ATP without need for oxygen B. Why is it important not to incubate the fermentation tubes beyond 24 hours? You may not get accurate results. Although sugar is the primary nutrient used‚ when a microbe runs out of it‚ protein or other nutrients will be attacked This causes changes in the color of the medium because of the pH indicator added to detect acid production. When proteins

Photosynthesis Lab Report Purpose: To research the effect of different wavelengths (colors) of light on plant growth during photosynthesis. Background Information: Photosynthesis is the process by which sunlight is captured by chloroplasts within plant cells and turned into energy. This energy is used to help the plant grow roots‚ leaves‚ flowers and fruit. Energy is required by living things

A streak culture was performed on a Tryptic Soy Agar Plate for isolation and purity and then incubated at 37 degrees Celsius for 24 hours. A gram stain was performed to determine whether the bacterium was a gram negative or a gram positive. After performing the gram stain‚ I concluded that by the appearance of purple spherical clusters resembling grapes that is was a gram positive cocci. A Catalase test was then performed using hydrogen peroxide. A positive catalase test was observed

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. Materials and Hazards Analytical balance‚ coffee filter‚ pencil‚ paper‚ cup‚ American beans‚ Nigerian beans‚ Mexican beans‚ calculator‚ and paper. Raw Data Bean Total Mass w/ Cup Number
