Experimental Research When we want to learn about the humans‚ we must experiment on the subject. There are current scientific and medical research that needs to be done on human‚ in this case there will be an experiment involving a clinical drug trial; a pharmaceutical company wants to test a new sleep aid. In order to learn more about the new sleep aid‚ researchers would need to study on patients who have trouble sleeping through the night. This can be the case of insomnia or it can be symptoms

expected results of the experiment being reflected by figure 3‚ some errors were noted. For example‚ at the start of the experiment‚ we had trouble locating the vacuoles within the tetrahymena and may have miscounted the final number of vacuoles because of equipment failure. Due to this error‚ the data collected in this experiment cannot be used for analysis in regards to research purposes. This error might have due to human related errors such as improper cleaning of the microscope that were used in this

Lee 1 Kwan Woo Lee Lab Report#1 Measurements in resistive networks and circuit laws laboratory Abstract: The purpose of this lab is to verify the Ohm’s Law‚ Kirchhoff’s Voltage and Current Laws. As well as the introduction to the voltage division. The Ohm’s Law states that the current through a conductor between two points is directly proportional to the potential difference across the two points (V = IR). The Kirchhoff’s Voltage Law states that the directed sum of the electrical voltage

Effects of Alcohol‚ Caffeine‚ and Temperature on the Heart Rate of Daphnia magna Joseph Ezra Gallo BY124L MW 8:30-11:30 Introduction Ectothermic animals are animals whose body temperature is affected by their surroundings. This means that if the environment is cold the animal will be cold. If the environment is warm the animal will be warm. This is because the animal doesn’t have the capability of regulating its body systems to keep a constant body temperature. When an ectothermic animal is

the highest amount rise‚ which will show us the optimal color of light for photosynthesis. These different colors of light included blue‚ red‚ green‚ fluorescent‚ regular light‚ and classroom light. The classroom light was our control cup during the lab. Before we conducted our experiment‚ the class learned about the photosynthetic process of‚ not only spinach discs‚ but plants in general. As I did more research on photosynthesis‚ the Calvin Cycle‚ wavelengths and pigments required for a proper equation

Alyssa Caparelli Organic Chemistry 12A Professor Alston October 28‚ 2014 Isolation of Chlorophyll and Carotenoid Pigments from Spinach Purpose The purpose of this experiment was to isolate ß-carotene‚ chlorophyll-A‚ and chlorophyll-B from spinach using column chromatography. Spinach was dehydrated using ethanol‚ and the pigments were extracted with dichloromethane. The spinach extracts were dried using CaCl2. Then‚ the solid pigments were run through a column using a non-polar solvent‚ hexane

The purpose of this experiment is to find what design of calorimeter captured the most energy from a combusted chip. To find this‚ we tested each design‚ and calculated the amount of energy it captured from a baked potato chip. The two basic forms of energy are kinetic energy and potential energy. Kinetic energy is the energy of motion. A ball has kinetic energy when it flies through the air. The ball has the ability to do work in that it can act upon other objects with when it collides. Potential

purpose of antimicrobial drugs is either to inhibit virus replication‚ without harming host tissues or to interrupt the cell processes or structures of bacteria‚ fungi‚ and protozoa. This lab has brought great interest to me because this is the way physicians’ control/treat infectious disease within our bodies. In this lab‚ chemotherapeutic agents were evaluated by the disk-diffusion method. Chemotherapeutic agents are placed on the surface of a Petri plate containing Mueller-Hinton agar‚ which allows
