Sedimentator Lab Introduction: in this lab we will be working with a sedimentator to observe and classify sediments. A sediment is naturally-occurring material that is broken down by processes of weathering and erosion‚ and is subsequently transported by the action of fluids such as wind‚ water‚ or ice. Side One Purpose: to observe and classify sediments Part I 1. Gently shake the sedimentator to loosen the sediments and lay the sedimentator on its side 2. Observe the water

Biophysical Ecology Abstract: There are many patterns that can be observed throughout our environment. In this experiment‚ the temperatures of organisms in a biophysical environment were analyzed to see if a pattern could be recognized that was related to the behavior of an ectotherm. An ectotherm is an organism that relies on the environment to regulate its body temperature. Organisms such as Pseudemys (turtles) and Lacertilia (lizards) are examples or ectotherms. After arriving at Maxcy Gregg

Introduction: To achieve genetic experiments with haploid organisms‚ genetic strains of different genotypes must be crossed from one another. Following fertilization and meiosis‚ the meiotic products can be analyzed as the ascomycete fungus‚ Sordaria fimicola. Sordaria can be used as a model to study meiotic segregation. The trait followed was the ascospore color. Ascospore color is a single gene trait therefore it is easily observed under a light microspore. Which allele is dominant is very tough

Ahmad Shrab . Introduction This lab is purposed to familiarize basic equipment and techniques used in the study of microorganisms. In addition‚ learn some basic techniques used in identifying prokaryotes and make and view microscope slides of some common prokaryotes. In this lab ‚ I worked two experiments ‚ the first one is cultivation bacteria "colony "‚ and When microorganisms are cultivated

Procedures: In the first lab‚ seven test tubes were attained and six of them were filled with the solutions that were listed (Na Pyruvate‚ MgSO4‚ NaF‚ Glucose‚ Water‚ and yeast suspension). The last test tube was filled with water. After they were filled with the solutions they were incubated at 37 degrees Celsius for about forty minutes. After the forty minutes passed take the test tubes and measure the height of the bubbles that formed in millimeters. For the second lab‚ attain three beakers‚

Peterson Chem. 243a Matt Judd‚ Sec. 25 Date Performed: 10/15/03 Abstract: The objective of this experiment is to efficiently perform a fischer esterification of 1-Hexanol to form water and hexyl acetate‚ and to confirm the esterification with a nuclear magnetic resonance (NMR) spectroscopy. It was found that 0.3963 grams hexyl acetate was formed with a percent yield of 33.2%. The product was confirmed using NMR‚ IR‚ and boiling point confirmation. Backround: A Fischer Esterification is the formation

Egg Lab Report Introduction: An egg is a model of a human because the egg has a cell membrane like humans do inside and outside of the body that let things pass through like water. We can use eggs to study the effect of changes in the external environment on the internal environment by having harsh environments like putting the egg in only alcohol and see what happens to the inside of the egg. Diffusion is the movement of a substance down its concentration gradient from a more to a less concentrated

one outlier that was strange was the one paper towels. Only 14 of the 15 seeds germinated in that group. The difference that we could observation was the healthiness of the plants. IV. Conclusion Paragraph 1 Recap (Evidence): The purpose of our lab was to see if the amount paper towels would affect the germination of the seeds. My hypothesis was‚ if I increase the amount of paper towels‚ then the germination rate would increase too. We observed the petri dishes in class and we would add 2 ml of

The pGLO lab is a lab where students attempt to put the genes that make a jelly fish glow into E. Coli. After a process called transformation‚ the process in which a cell takes up and expresses a new piece of genetic information‚ the E. Coli will be able to glow and will be antibiotic resistant. The students first need to learn a couple of techniques before they are able to begin this lab. The first technique they will need is how to keep their environment sterile. They must learn to only open their

The starting material for this lab was the dialyzed sample (stored at -20ᵒ C) from the previous lab. The CM sephadex resin (taken in a 50 mL tube) was already made swollen using Buffer C (20 mM HEPES‚ pH 7.9; 1 mM EDTA; 50 mM KCl). The dialyzed sample was thawed to the room temperature and gently poured over the resin. The tube was capped and kept on a rocker at room temperature for 1 hour. The tube was then centrifuged in a HS-4 rotor at 2500 rpm (1200g) for 5 minutes at 4ᵒ C. Supernatant was discarded
