Toxicology Lab 1. In this investigation‚ a wide range of concentrations of Sodium Chloride (NaCl) solution were created and the effects that they had on radish seeds were tested. This ultimately created a doseresponse experiment in which it was detectable whether or not radish seeds were a reliable bioassay for the toxicity of NaCl. The goal of this experiment was to determine a correlation between toxicity and seed germination/radicle

The experiment we conducted in lab used three different species of algae‚ Macrocystis (brown)‚ Plocamium (red) and Ulva (green). Before we conducted anything‚ we first measured the initial oxygen concentration in the water that was used to house each alga. This was done because in the water that we used there happened to be phytoplankton which can respire and photosynthesize. If we didn’t take them into consideration our results would end up skewed. Once that was known we took a piece of each algae

Photosynthesis and Semi-Conductor based Solar Cells Plants‚ by shear desire to survive have developed the worlds most efficient and reliable power supply by way of photosynthesis. Scientist for years have tried unsuccessfully to duplicate the process of photosynthesis. However‚ for the purpose of this paper‚ I will compare and contrast how energy and electricity is generated through photosynthesis and a semi-conductor based solar cell. In addition‚ this paper will explain how both processes

Lab 5 The Diffraction Grating Chinua McDonald Objective: To measure the wavelength of light with a diffraction grating. Theory: The two types of diffraction gratings are the transmission and reflection gratings. They are made by ruling on a piece of glass or metal a number of evenly spaced lines with a fine diamond point. Diffraction phenomena can be analyzed in terms of Huygens’ principle‚ according to which every point on the wave front of a wave should be considered as a source

Reconciliation In "Up the Coulee‚" Hamlin Garland depicts what occurs when Howard McLane is away for an extended period of time and begins to neglect his family. Howard’s family members are offended by the negligence. Although his neglect causes his brother‚ Grant McLane‚ to resent him‚ Garland shows that part of having a family is being able to put aside negative feelings in order to resolve problems with relatives. Garland demonstrates how years apart can affect family relationships‚ causing

Thermometer Works - pg. 23 Purpose: What makes the liquid within a thermometer go up and down? Hypothesis: If the liquid is placed into objects of different temperatures‚ then the liquid moves up in the hotter substance and down in the colder substance‚ because of the change in the molecular energy when the water is hot and when the water is cold. Materials: Test tube‚ about 20 mL Isopropyl rubbing alcohol‚ 91% Small cup 2 small disposable water bottles (8 oz.) or 2 small beakers Food
