Bio Lab Report Erica Patterson September 10‚2013 Intro to cellular and molecular Biology Lab Abstract: In the Biology Laboratory Manual by Darrell S. Vodopich and Randy Moore are results to a similar experiment. The studied the hypothesis of carbon dioxide production by yeast fed sugar is not significantly different than the carbon dioxide production by the yeast fed in protein. Their hypothesis is the one that has helped formulate ours. We also will be answering the same to questions “What

When Chemicals React! Mr. Bell’s honors level chemistry class conducted an experiment during their lab demonstrations‚ this consisted of elements such as phosphorus and calcium chloride in their experiment. This along with another hydrogen based sunstance produced‚ what looked like a pinkish-looking substance inside of their flasks that were at their lab stations. Sophmore Kelly Caudel said‚ “ I actualley enjoy doing the experiments in this class‚ because it gives us a chance to get away from

ANALYSIS OF BACTERIA GROWTH Abstract Bacteria can be found everywhere on the earth. Bacteria are single-celled organisms that lack a nucleus‚ mitochondria‚ and chloroplasts and are surrounded by a cell wall containing a peptidoglycan layer. They are defined by their small size and wide range of shapes. In this experiment we separated organisms in a mixed culture to study the colony morphology and physical characteristics and determine which organism was present in higher numbers‚ as determined

Bioinformatics Lab Report Hypothetical Phylogenetic Tree: Using a cladistic approach‚ we constructed a hypothetical phylogenetic tree of many different plant taxa by comparing their morphologies. We first decided to sort the various types of plants into groups based on morphological features. After sorting these plants into five different groups we began to determine how the plants differed from eachother in the group and what features set them apart. From this we started to create

Lab Report Enzymes (must be typed) Name: Amanda Gallegos Date: 2/15/15 Section: BIOL 101GL What is the Hypothesis of this experiment? (3 points) -The highest temperature will affect the reaction rate of enzymes. What is the dependent variable? (1 point) -Change of rate/product/color/absorbency. What is the independent variable? (1 pt) -The temperature. Explain in detail the procedure that you followed (including amount of substrate‚ enzyme etc‚ and the whole procedure including incubation times)

the percent yield by dividing the expected yield‚ the amount of product that should be produced based on your stoichiometric calculations‚ by the actual yield‚ the amount of product that is experimentally obtained from a chemical reaction. In this lab‚ I have determined the reaction for mixing two reactants together; I measured out 0.005 moles of each reactant‚ lead (II) nitrate and potassium chromate. I dissolved‚ mixed‚ and made them react to make products; I compared the mass of the two reactants

Bacteria and Archaea Bacteria and Archaea All single-celled organisms in the Bacteria and Archaea domains are referred to as prokaryotes. Prokaryotes are organisms whose genetic material is not contained within a nuclear envelop. These cells are profoundly important to the environment‚ medicine‚ and industry. (Postlethwait & Hopson‚ 2010‚ p. 196) Bacteria and Archaea are similar in shape‚ size‚ and appearance. They are both found occurring as rods (bacilli)‚ spheres (cocci)

Enzyme Lab Report Introduction The objective of this experiment was to determine if changes in pH or temperature affected the activity of enzymes‚ specifically the enzyme sucrase. Enzymes are protein molecules that act as biological catalysts to increase the speed of the reaction or to lower the activation energy of that reaction. However‚ the activity of an enzyme can be affected by physical factors such as pH and temperature because these factors alter the structure of the enzyme (Freeman‚ 2011)

When the water being heated reaches 70°C-80°C‚ remove from the heat and let it sit on the lab bench‚ stirring occasionally. Record the temperature of the hot water to the nearest 0.2°C. Quickly‚ remove the lid from the calorimeter and pour in the hot water. Replace the lid. Stir for 30 seconds‚ then begin monitoring the temperature of the combined
