How The Scientist Discover The Interior Of The Earth Two ways that Scientist may study and find the interior of the Earth are with Meteorites and Magnetic Fields. The scientist may use meteorites to discover the interior of the Earth’s earlier solar system by studying the meteorites that arrived on the Earth. The scientist might use magnetic fields by the science advances which involves measuring the ocean and coming up with a hypothesis. Therefore‚ the meteorites and the magnetic fields all

Lab 6 Biomechanics of Frog Skeletal Muscle I. Purpose This exercise is designed to demonstrate some mechanical and physiological properties of skeletal muscle using the gastrocnemius muscle of a frog. II. Performance Objectives At the end of this exercise the student should be able to: 1. Define minimal (threshold)‚ subminimal‚ maximal‚ and supramaximal stimulus. 2. Explain what is meant by a “graded” response. 3. Draw a diagram of the setup used in this lab exercise. 4. Calculate the

Experiment 8 “Lipids” and the purpose of the lab is to become familiar with the properties and reactions of certain lipids called fats or oil. For this lab‚ students are testing the properties and reactions of lipids and soap will be prepared and its properties will be tested. To begin the experiment‚ place 5 mls of water‚ ethyl alcohol‚ chloroform‚ and toluene in to four clean test tubes and add 1 drops of cottonseed oil to each test tube. Shake it and record your observation. To do part B‚ in three

Arlind Mara Paper Towel Lab Report AP Biology 15 September 2011 Which Towel is The Quicker-Picker Upper! To determine which of the most popular paper towel brands such as Bounty and Marcal would be the Quicker-Picker-Upper I conducted the following experiment during which I dipped 6in X 6in squares of paper towels into 100mL and measured the amount of water absorbed by the towels in 20 seconds. After averaging all 3 trials for the paper towel brands that I tested I arrived to the conclusion

The purpose of this lab that was completed was to observe standing wave patterns in clamped strings‚ and understand the effect of the standing wave frequencies of changing the length (L)‚ tension (T)‚ and linear density (p) of the strings. Standing wave patterns in strings are observed at certain excitation frequencies for special values of L‚ T‚ and p. A standing wave can be defined as a vibration of a system in which some particular points remain fixed while others between them vibrate with the

Backward Bending Slutsky Equation In the Labor Supply Model‚ consumer has a choice between consumption and leisure. If they were to reduce their leisure and allocate more time working‚ they will be able to consume more. The amount of labor and consumption are determined by the interaction of consumer’s preferences and budget constraint. In this model‚ the utility function to be maximized is U(C‚L)‚ where individual cares about consumption (C) and leisure (L). The utility function is subjected
