Caution: Wear eye protection because of the possible shattering of dropped glassware and because acids are used in this experiment. Seliwanoff reagent is resorcinol dissolved in 4M hydrochloric acid. The acid is corrosive (burns human tissue). If any of this solution gets on your skin‚ wash the solution off immediately with water. Avoid breathing the vapors of the solution. Protect your hair‚ clothing and flammable materials from the open flame of the burner. Make sure the beaker is well supported when

Broths were incubated at 370C for 24 hours. The cultures were then diluted 1:100 with fresh medium. Individual wells of sterile 96 well-flat bottom polystyrene tissue culture treated plates (Sigma-Aldrich‚ Costar‚ USA) were filled with 200 µL of the diluted cultures. The control organisms were also incubated‚ diluted and added to tissue culture plate. Negative control wells contained inoculated sterile broth. The plates were incubated at 370C for 24 hours. After incubation‚ gentle tapping of the

cardiovascular system and the digestive system are the three body systems that are involved with energy metabolism. There are two kinds of activities involved with metabolism processes‚ these are; building up of body tissues and energy stores and the breaking down of body tissues and energy stores to produce more energy to for the proper functioning of the body. There are two types of metabolism‚ these are catabolism and anabolism. Catabolism is the process that involves the breaking down of large

experiment is to answer questions associated with the onion root tip photos that are pictured in the lab. The questions for this lab will be drawn from the discussion and review section at the beginning of the mitosis lab. Once that section has been reviewed we may begin to answer the questions. Hypothesis-There is no hypothesis for this experiment Procedure-Review discussion about mitosis‚ examine the six photos of the mitosis of onion root on the worksheet provided. After this is done‚ record

LABORATORY 3: LABORATORY 3: Basic Chemistry for Investigating Living Systems Abstract The purpose of this experiment was to explain how colorimetry can be used to qualitatively detect cellular chemical components; to chemically differentiate between proteins‚ sugars‚ starches‚ and lipids; to identify the roles of molecular components in living systems; to comprehend the value of using a systematic approach to research; and to describe why hypotheses‚ controls‚ standards‚ and quality control

Biology For Majors October 4‚ 2012 Abstract We examined the reaction an enzyme has when its concentration‚ pH and temperature are altered. In order to do this‚ we added different levels of pH into different test tubes with the enzyme (sucrose)‚ and substrate (sucrose)‚ and we then inverted the tube. The higher pH produced more enzyme activity. Temperature effects enzyme activity by decreasing its stability when the temperature increases. Oppositely‚ low temperature levels resulted in little to no

Danny Fish 10/9/11 Chemical Testing To identify An Unknown The hypothesis tested was that depending on the solution presented‚ which would test positive for one of the following‚ proteins‚ carbohydrates‚ or lipids through use of chemical testing. (Sudan IV‚ Benedicts’ Solution‚ Iodine‚ Biuret’s) . In order to gain more information for the hypothesis‚ one must know how to test for said macromolecule. Each of the above stated molecules has their own individual solution that will in turn identify

Big Idea 2 Biological systems utilize free energy and molecular building blocks to grow‚ to reproduce and to maintain dynamic homeostasis. Living systems require both free energy and matter to maintain order‚ grow and reproduce. Organisms employ various strategies to capture‚ use and store free energy and other vital resources. Energy deficiencies are not only detrimental to individual organisms; they also can cause disruptions at the population and ecosystem levels. Biological systems must both
