Lab Report: Stoichiometry Lab Oct. 27‚ 2011 Claire Elizabeth Lab Partners: Hannah Signature:___________________ Introduction- Baking soda and vinegar are two common materials found in almost every household. That‚ plus the fact that all the starting and finishing materials are non hazardous and safe‚ is why this is one of the first chemical reactions that many people are exposed to The purpose of this experiment tests which of the two reactants (vinegar and baking soda) is the limited

1 1/14/12 Mitosis Lab Write-Up Purpose: The purpose of this lab is to understand the phases of mitosis through a hands on experience and not just textbook information. The objective is to visually determine each phase through a microscope with a clear understanding of what is happening. With this knowledge and this visual a picture is to be drawn as descriptive as possible for each phase. Materials: The materials needed are; 1) Microscope 2) A slide containing plant cells 3) Blank paper 4)

Discussion: We have made four set-ups in two different specimens. Onion and Boat of Moses skin with water‚ 2%‚ 5% and 10% salt (NaCl) Solution. Based on our experiment‚ the result of the set up explains that the presence of the salt solution results in outward diffusion of water and the collapse of the protoplast. In table 1‚ we have observed under the microscope that the onionskin mounted with water has no results of plasmolyzed cell (0%). This time‚ we have repeated the procedure with 2% salt solution

refers to the kind of inheritance in which the trait is produced from the cumulative effects of many genes in contrast to monogenic inheritancewherein the trait results from the expression of one gene (or one gene pair). In humans‚ height‚ weight‚ and skin color are examples of polygenic inheritance‚ which does not follow a Mendelian pattern of inheritance. pleiotropy is the single gene controlling or influencing multiple (and possibly unrelated) phenotypic traits. Mutation in this type of gene will

Lab Report Janice Chisholm SCI207: Dependence of Man on the Environment Instructor: Lee Ott April 28‚ 2013 1. What patterns do you observe on the information table 4? While observing the information in table 4‚ it appears that the number of fish changes from time to time and the oxygen increases and / or decreases when this occurs. 2. Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water?

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

Tim Readmond AP Biology Lab Report I. Title a. Modeling Diffusion and Osmosis II. Introduction a. If one places a 1.0 M solution of glucose inside a bag and then places that bag into a beaker containing a 1.0 M solution of sucrose‚ the percent of mass lost in the bag is 10.5%. The solution in the bag is hypertonic while the solution in the beaker is hypertonic‚ which is why water moves from the bag to the beaker and the bag loses mass. b. The purpose of this experiment is to see whether

The Comparison and Contraction Between Various Skin Cells By: Michael McDaniel‚ Latoya Gates‚ Cristy Barfield‚ and Danielle Chapelle Abstract During this experiment we planned to compare and contrast human cheek cells of a variety of age groups‚ different stages of skin‚ and difference in species. We wanted to see if age could correlate to cell structure and size‚ if animal and human cells differed and if epidermal and cheek cells could differ in shape‚ size‚ and color. The age groups that

commonly used application of the Michelson Interferometer is in imaging cells. In this application‚ the Michelson Interferometer is mated to a microscope and the cell is in one arm of the interferometer. When light passes through the cell‚ it undergoes a phase shift which depends on the cell thickness and organelles within the cell. The fringe pattern produced can be used to construct a three dimensional image of the cell. ! ! A commonly used set up of the Michelson Interferometer is shown
