Introduction: This Electrical Measurements Lab is designed to give students an introduction to talking measurements from a breadboard. Students have two available methods for taking voltage‚ current‚ and resistor measurements. One of which‚ is to use a standard multimeter to take measurements. However‚ all measurements in this lab report come from the digital NI ElVIS board. A. Resistance: Given three resistors of different color codes‚ the theoretical resistance can be found by apply the standard

animal though? In this experiment we are using lab mice‚ Mus musculus‚ to see if the introduction of a predator scent (fox urine) increases‚ decreases‚ or has no effect on the metabolic rate within them. We will calculate the mass specific metabolic rate and use a t-test to determine if there is a significant change in metabolic rate when the mouse is exposed to the predator urine and when it is not exposed. With these mice being born and raised in a lab‚ the fox urine should have no effect on the metabolic

Raquel Johnson October 19‚ 2014 Solids: Recrystallization and Melting Points Organic Chemistry 2423 Lab Report: Recrystallization Abstract: The purpose of this lab was to purify an unknown compound by recrystallization. Taking an unknown compound and identifying it by purifying it from its impurities through the use of hot gravity filtration. Then to determine the unknown you were to take the melting point. An unknown compound was recrystallized from hot water to produce 0.99 grams (67% recovery)

not exist (Lab Manual 3 pg. 1). They help in many different ways that are useful to the body of living organisms. Enzyme are used to speed up chemical reactions (Lab Manual 3 pg. 1). Through this process‚ they are considered very unique because they are not altered or consumed within the reaction (Lab Manual 3 pg. 1). This is why enzymes are considered biological catalysts. They also do not alter the equilibrium of a chemical reaction nor the amount of free energy that is released (Lab Manual 3 pg

Bio Lab Report Erica Patterson September 10‚2013 Intro to cellular and molecular Biology Lab Abstract: In the Biology Laboratory Manual by Darrell S. Vodopich and Randy Moore are results to a similar experiment. The studied the hypothesis of carbon dioxide production by yeast fed sugar is not significantly different than the carbon dioxide production by the yeast fed in protein. Their hypothesis is the one that has helped formulate ours. We also will be answering the same to questions “What

Osmosis The purpose of this lab is to study how membranes of plant and animal cells react when exposed to different solutions. The first experiment involves purple onion skin and the second involves rat blood in various solutions. I needed to understand certain terms before preforming this lab to be able to efficiently explain what is happening to the cells. Diffusion is the tendency of a substance to move down its concentration gradient from a more concentrated to a less concentrated area.

This lab specifically does not require the knowledge of what each organism does when introduced to another living organism‚ like a human. Figuring out the type of bacteria could help with further experiments. The idea of the unknown bacteria lab is to show

Name: Danielle Title: Unknown Lab Report Introduction: There are many reasons for identifying an unknown bacterium. The reasons range from medical purposes‚ such as determining if the unknown could cause ailments in living things or knowing what microorganisms are needed to make antibiotics. The experiment was done by applying methods in order to identify an unknown bacterium. An unknown bacterium was handed out by Dr. Honer. The appropriate tests were prepared and applied. The

Catalase Lab Purpose: To observe the effects of hydrogen peroxide on living tissue and non-living materials‚ showing the presence or absence of catalase as observed by the presences of bubbles. Hypothesis: If we pour H2O2 on certain substances‚ the catalase will break down and bubbles will appear at the surface. Data table: Name | Time | Observation | Raw Potato | 1 min. 30 sec. | Slow reaction‚ barley any bubbles. | Raw Liver | 5 min. 30 sec. | Extremely fast reaction‚ very foamy‚ Big

Michele Baden Bio 100 – 05 ALLELOPATHY INTRODUCTION The purpose of this lab was to observe the effects of chemical warfare among plants. Plant seeds compete with other plants and seeds‚ for sunlight‚ and nutrients in order to germinate. In order to win dominance over other seeds‚ and reduce competition‚ plants produce and release a chemical in order to prevent other seeds from germination. This type of chemical warfare is referred to as allelopathy. Allelopathy exists in many parts of the plants
