Introduction: There are times when it is necessary to go through something both inside and outside‚ literally‚ to learn. This was exactly the case with virtual lab #11 where the experiment called for an examination of an earthworm’s exterior anatomy and interior anatomy. The earthworm as a whole is considered the dependent variable as we cannot change it. However‚ the labels to be placed can be moved so they are the independent variables. My hypothesis is quite elementary. I believe that after studying

Morgan Kimmerle Monday Lab Dr. McCorkell Abstract The purpose of this study was to cross and analyze the reciprocal crosses of wild flies and mutant flies. In this lab Drosophila melanogaster commonly known as fruit flies were used to understand some important genetic principles that were once proposed by Gregor Mendel. Mutant traits can be autosomal dominant‚ autosomal recessive traits‚ or even sex-linked dominant and sex-linked recessive. F1 and F2 generations were obtained by performing

The Namib Desert 5/13/96 Period 6 The Namib Desert is a parched and rippled desert‚ an endless expanse. It stretches along the wouthwest coast of Africa from Angola in the north‚ through Namibia‚ into South Africa. The name Namib means "emptiness." About 1‚700 km (1‚060 mi long and 100 km (60 mi) wide‚ the desert is bordered on the west by the Atlantic Ocean. The Namib has an approximate area of 170‚000 sq km (65‚640 sq mi). It rises from sea level 914 m (3‚000 ft). Temperatures

Introduction In the amylase lab‚ it was being tested if amylase‚ an enzyme found in saliva‚ would be denatured by being put in an acid or high temperatures. This lab is about denaturing amylase. It is tested by exposing it to pH and temperature changes. It is then mixed with Benedict’s solution‚ is a solution that changes color from blue to reddish brown when maltose is present. Amylase breaks starch into maltose‚ so is the amylase isn’t denatured‚ it should change colors. Amylase is an enzyme

Formal Lab Report | Chemistry | | Student name: Sara Hattar Grade: 10 ”C” | | Teacher: Christine Ziadat | | | Title: Investigating the effects of changing the concentration of an acid on the rate of reaction between HCl and Magnesium. Aim: In this experiment we are going to see the effects of using three different concentrations of HCl when added to Magnesium metal on the rate of reaction. Hypothesis: If the concentration of the acid increased in reaction between HCl (the acid)

______________________________ Week 1 Lab Goals: 1. Choose your lab group. 2. Learn about lab safety. **IMPORTANT – All students are expected to wear a lab coat and goggles in lab at ALL times. As well‚ you are not permitted to wear shorts or open-toed shoes. If you are not dressed appropriately for lab‚ your TA will dismiss you. You are permitted to return to lab with proper attire and equipment‚ but the rules for lateness will apply (see the syllabus). If you do not return to lab with proper attire

solution to the bottle ATP and the dropper was placed back onto the bottle. The bottle was rolled between the palms of a pair of hands to until the powder was dissolved. The powdered firefly lantern was poured into two Petri dishes in each of the four stations. One was used for the control and the other dish was used for the experiment. To each of the Petri dishes 1 mL of buffer solution was added. At station 1 the control two drops of ATP were added to each Petri dish. The control Petri dish

Data Analysis: 1. What was the temperature change for the water in the calorimeter (ΔTwater)? 3°C 2. What was the temperature change for the metal sample (ΔTmetal)? Assume the intial temperature of the metal was the same as the temperature of the water it was boiled in. 70°C 3. What was the specific heat of water in J/g°C? 4.186 J/g°C 4. Using the following equation‚ your answers to questions 1-3‚ and your data table‚ determine the specific heat of the metal sample you tested. 5
