LAB Report #3 Introduction: In this lab we have focus on Isolation of bacteria from environment. Microorganisms are found throughout the environment: in the air and water; on the surface of any object such as clothes‚ walls‚ furniture; in soil and dust; and on and in our own bodies (skin and mucous membranes). In order to demonstrate the ubiquity and diversity of microbes in the environment‚ samples from immediate areas of the environment and/or from your body will be obtained and cultured

Fortunella parent‚ Kumquat‚ lends a dense shrubby habitat‚ small leaves and a hardy constitution‚ whereas the Citrus reticulata‚ Mandarin Orange‚ lends thorns‚ tasty fruit and ease of peeling. So the Calamansi has small‚ easy to peel fruit with the sour acid flavor. In Central Florida‚ calamansi trees yield abundant fruit throughout the year. When the trees are covered in blossoms‚ they emit an intoxicatingly sweet beautiful fragrance that carries with the breeze. Many of my neighbors and co-workers have

Lab Report: Halogen Reactions Purpose: This experiment will allow for exploration into some of the properties of Group 17 elements (halogens) and their compounds. More specifically‚ the solubility properties of these halogens will be used to predict their reactions. The relative electronegativities of the halogens will be determined. Halides‚such as Cl-‚ Br-‚ and I- will be used to make these determinations. Because this lab is qualitative rather than quantitative‚ there are no calculation

Nervous System lab was designed to measure reaction times by using a variety of tests that affect the heart rate. These tests were the startle‚ stroop‚ Valsalva maneuver‚ diving reflex‚ and a test of our choice. The test our group chose to measure the heart rate in response to doing a trust fall to anticipate the stress right before the fall. To begin this lab we chose a participant‚ and then hooked their finger up to the pulse transducer sensor. Using the chart 5 program on the lab computer the participant’s

Lab Report: Toothpickase and Enzymes September 19‚ 2012 Olivia DePhillips Lab Partner: Joy Morgan Meyers Signature: Introduction Enzymes are biological molecules that catalyze chemical reactions. In enzymatic reactions‚ the molecules at the beginning of the process‚ called substrates‚ are converted into different molecules‚ called products. Almost all chemical reactions in a biological cell need enzymes in order to occur at rates sufficient for life. Like all catalysts‚ enzymes work

Lab Report 7: Analysis of Cereal Introduction: The objective of this lab was to consult for the FDA regarding a recently surfaced scandal involving false reporting of iron content in cereal as well as iron tablets. The makers of the cereal and the iron tablets‚ respectively‚ were allegedly reporting higher amounts of iron in their products than actually existed‚ as a way to save money but continue to provide products with “adequate” amounts of iron. The FDA needed consulting in order to analyze

Adwoa Fosuah Bio Psych Lab Report 4 Cold Pressor Task Aim The cold pressor test is done by having the subject submerge their hands in a bucket of cold water to determine cardiovascular changes such as blood pressure and heart rate. For this experiment we wanted to know how long participant can keep their feet in the bucket of ice water before they experience any pain while looking at neutral and positive pictures and also rate the intensity of their pain. For this reason we hypothesized that
