’Neil 2002). The particular conditions that had to exist for this to apply were that the population had no mutation‚ had no natural selection‚ was a large population‚ had only random mating‚ and had no migration. For the cases to follow later in the lab‚ Cases 1 and 2 exemplify Hardy-Weinberg conditions. All of the others either have selection or not enough members in the population‚ which will be the most-closely observed

(Hunter 1976). Using an even more closely related species’ erythrocytes in diffusion experiments would provide an even better model for human cell behavior. Additionally‚ finding out more about diffusion mechanisms may allow scientists to synthesize compounds that have specific desired diffusion characteristics. This will allow better targeting of drugs‚ which would have a great impact on medicine for a variety of disorders. Works Cited 1. BI 108 Section D2. 2011. Principles of Biology II. Biology

Chromatography • • • Separation based on polarity of compounds Two potential phases for a compound to exist in: mobile and stationary Partitioning of compounds between mobile phase and stationary phase occurs: o Compounds that are less polar move more in the mobile phase‚ those that are more polar “stick” more on the stationary phase o These polarity differences cause compounds move at different rates and therefore can be separated 1. Mobile Phase: the phase the moves; can be gas or

Introduction and Purpose: This lab focuses on how weight affects the time it takes for a rotocopter to fall from a drop height of 1 and 2 meter(s) respectively. The primary goal of this lab is to investigate and explain the relationship of these two factors. During the process of conducting this experiment‚ learning to design a lab will also be achieved. Research Question: What is the effect of weight on the time it takes for a rotocopter to fall from a drop height of 1 and 2 meter(s)? Variable

Impurity Lab Report Aim: To find out the difference of the boiling point and melting point when adding impurity (salt) to water. Diagram: Method: 1.Set up the apparatus as shown in the diagram 2. Get a known amount of ice in the beaker (half full)‚ and a known amount of salt in another beaker 3. Measure the temperature (melting point) of the ice without adding any impurity (salt). 4. Measure the temperature (melting point) of the ice after adding the salt into the beaker. 5. Heat up

Lab Report Procedure 6.1: Perform Benedict’s test for reducing sugars. Introduction: Benedict’s tests allows for the detection of the presence of reducing sugars. All monosaccharides are reducing sugars since all of them have active carbonyl group. Some disaccharides that are exposed to a carbonyl group are also reducing sugars but less reactive than monosaccharides. By mixing the sugar solution with Benedict’s solution and heating them‚ a redox reaction will occur. The copper (II) sulphate

Lab Report Density Name: Period: Problem How do you calculate Density? What units did you use for volume‚ mass‚ and density? When the cubes are placed in water which one will sink 1st? What is the ranking of the cubes lightest (1) to heaviest (10)? Is it true that the cube with the most mass will have the most density? Hypothesis I think the 1st cube was aluminum I think the 2nd cube was steel I think the 3rd cube was brass I think the 4th cube was copper I think the 5th

ABSTRACT On the past two weeks‚ I have done an experiment on hydrostatics‚ or is also known as fluid statics (fluid at rest) within the fluid mechanics field of study. This condition explains that in a stable condition‚ the fluid is at rest. The use of fluid in doing work is known as hydraulics‚ and the science of fluid in motion is known as fluid dynamics. INTRODUCTION The natural nature of fluids are they cannot remain stationary under the application of shear stress. However‚ fluid

This lab experiment investigates the effect of listening to different types of music on one’s pulse. The experiment relates the circulatory system to the pulse as it measures how quickly the heart contracts and releases blood. Pulse is measured in beats per minute (bpm). One’s pulse is loudest near the heart‚ because there is more pressure closer to the heart. In contrast‚ one’s pulse is quieter the further away it is measured from the heart‚ because there is less pressure the further the distance

CHEMISTRY COURSE TITLE: General Organic Chemistry COURSE CODE: CHM 121 ‚ UNIT: 2.0 . INTRODUCTORY AND IMPORTANCE OF ORGANIC CHEMISTRY Organic chemistry is the study of the compounds of carbon. Carbon compounds are far more numerous than those of other elements because carbon are able to bond together to form a wide range of chains and rings. The subject is named organic chemistry because living organisms are composed of carbon compounds. Organic chemistry could be regarded as the
