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

Lab Report Density Name: Period: Problem How do you calculate Density? What units did you use for volume‚ mass‚ and density? When the cubes are placed in water which one will sink 1st? What is the ranking of the cubes lightest (1) to heaviest (10)? Is it true that the cube with the most mass will have the most density? Hypothesis I think the 1st cube was aluminum I think the 2nd cube was steel I think the 3rd cube was brass I think the 4th cube was copper I think the 5th

(2) being able to apply that understanding of the microbial world so that the benefits to the Earth and humans are known(6). This lab specifically does not require the knowledge of what each organism does when introduced to another living organism‚ like a human. Figuring out the type of bacteria could help with further experiments. The idea of the unknown bacteria lab is to show

Background: This lab involves the testing and measuring of water potential. Water potential (ψ) is the tendency of water to diffuse from one region to another. It measures the free energy available in water to do work. Pure water has a water potential of 0 (kpa--unit?). Water will move from an area of higher water potential to an area of lower water potential. Several factors‚ including temperature‚ pressure (ψp) and solute concentration (ψs) contribute to water potential. (citation-lab) The equation

Ketchup Lab Report Problem: People visiting fast food restaurants complained that ketchup was dripping onto their fingers and clothes. What could we do to insure that the ketchup will not drop all over the customers? Hypothesis: If I put one ketchup packet in a hotter bath then it will move faster down the styrofoam plate. Independent Variable: The temperature Dependent Variable: The viscosity of the ketchup’s “runniness” Constants: The type of ketchup

cells due to the sudden increase in water pressure within the cell) in animal cells or turgor pressure (the pressure created by the increase in water pressure within the cell) in plant cells. Turgor pressure prevents further osmosis‚ which causes the water potential outside the cell to be lower than that inside the cell. When placed in a hypertonic environment‚ the gradient in animal and plant cells are reversed and water exits the cell. This sudden release of water results in a shrinking membrane‚

Synthesis of Tetraphenylcylopentadienone Post-Lab Report Purpose- This experiment illustrates the use of adol condensation for the synthesis of a five-membered carbocylic ring. It is also a good demonstration of the impact extended conjugation has on the absorption of visible light. The reactants are bright yellow in color while the products are a very deep purple color appearing almost black. Introduction- The synthesis of Tetraphanylcyclopentadienone was a further example of the adol

heat content”. In this experiment‚ a certain amount of hot water‚ at a particular temperature‚ is poured into the calorimeter containing tap water of known mass and initial temperature (Hubsch‚ 2001). The equilibrium temperature is then measured and the mass of the whole mixture is measured. For part B‚ solid specimen shots of known mass were mixed with the tap water of known temperature in the calorimeter and a certain amount of hot water of known temperature is added. The equilibrium temperature
