Introduction The purpose of this experiment is to determine the maximum absorbance of fast green‚ and the chlorophylls‚ also in the case of fast green create a concentration curve to determine an unknown substance. Each test will use the spectrophotometer. Spectroscopy is the study of light. A spectrophotometer is a machine used to determine the absorbance of light at any given wavelength. It does this by using a source of white light through a prism‚ which gives multiple wavelengths that

“Comparing Average Rates of Respiration in Mealworms in Light and Dark Environments in a Manometric System” Mohammad Rafi 213552179 BIOL1000 LAB REPORT Oct 28‚ 2014 Hypothesis The biological hypothesis for this lab experiment was that the rate of respiration in mealworms would decrease in mealworms that were exposed to a dark environment compared to those mealworms that were exposed to a light environment. This hypothesis was based on the fact that oxygen levels tend to decrease in

Lab 1‚ Exercise 1 • Based on the information in Table 2‚ what patterns do you observe? The number of fish that I observed in a body of water increases until the dissolved oxygen was at 12 ppm. After that point‚ the number of fish declines slightly. • 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. When the dissolved oxygen levels increase‚ the number of fish that

1. No‚ I would not do pre-implantation genetic diagnosis if money was no object. I do not think that it is right to go through the genetic information of an embryo and decide what you want and what you do not want. I think that all physical attributes such as height‚ hair color‚ and eye color‚ should be decided naturally. As well as the physical attributes‚ I think genetic disorders and hereditary diseases should be left alone. If they were in the genetic makeup of the human embryo‚ then God has

Nicolette Lindberg 11/30/12 IB Biology 2‚ Period 1 Transpiration Lab Background Information- Transpiration is the loss of water from a plant. Plants transpire water out of the stomata in their leaves at a different rate in every environment. The amount of transpiration is affected by the environment‚ how developed the plant is to not lose as much water‚ the surface area of the leaves‚ and how affected the plant is by its environment (Von Bargen). For this experiment‚ the plant we used was (Viola

Lab 5 DECOMPOSITION (Nov 2‚ 2011) Introduction: Decomposition is the breakdown of organic material into its smaller molecules and elements. (This term is generally considered as a biotic process but one may find it also used to describe an abiotic process‚ e.g.‚ due to weathering.) The decomposing organisms may use the release of elements for nutrients and by breaking apart the carbon-carbon bonds in organic matter this can release energy for them. These smaller molecules and nutrient elements

Jan Levi O. Pangilinan Mr. Jestoni Basco BSIS – IIIB BIOS(Basic Input/Output System) 1. What is BOIS? The term BIOS (Basic Input/Output System) was invented by Gary Kildall and first appeared in the CP/M operating system in 1975‚ describing the machine-specific part of CP/M loaded during boot time that interfaces directly with the hardware (a CP/M machine usually has only a simple boot loader in its ROM). Later versions of CP/M (as well as Concurrent CP/M‚ Concurrent

Lab Report: Animal Behavioral Diversity Biology 112 Lucas LLona 5-7-13 1) a. Based on background knowledge regarding beta fish‚ I believe that the male beta fish will be the first out of the two specimens to display any aggressive behavior. b. - Pectorals flap at rapid speeds when the beta fish is uncomfortable and appears agitated. - The gill cover expands in size when the beta fish is uncomfortable. - Caudal fin moves quickly when agitated and also determines how quickly the specimen
