Introduction: Capture and recapture is a method to observe animals‚ give information on survival‚ recruitment‚ and size of the population. You capture the animals and mark them and release them. Mark and release repeatedly. Objective: The purpose of this experiment was to analyze the amount of marked beans of the beans we would catch. Hypothesis: If the number of marked beans represents the number of the mocking jays in the forest and the unmarked beans are the food supply then the mocking jays population

KEY: ABE Lab 1: Prelab: Page A17‚ Questions 1 and 2: 1. What does the term genetic disease mean? What examples of generic diseases do you know about? A genetic disease is a disease caused by an absent of defective gene in the DNA. Students may know of sickle cell anemia‚ which is a disease resulting from defective red blood cells; treatment of sickle cell anemia focuses primarily on relieving pain and controlling infections and other complications that may occur. 2. Adding human DNA to bacteria

react. Theory: The purpose of this lab was to confirm the chemical formula of magnesium oxide by comparing the masses of pure magnesium solid prior to any reaction and magnesium oxide solid after a reaction between all of the magnesium and oxygen from the air when heated from a Bunsen burner in a crucible. Using molar masses of both magnesium and oxygen‚ an expected percent composition‚ by mass‚ was found and compared to our experimental results. Experimental: 1. Setup ring stand 2. Obtain desired

Lab Questions Unit 4 1. Who were the Poor Clares? Why is it somewhat surprising that they were accomplished musicians? Poor Clares were nuns from a catholic church. It is surprising that they were skillful musicians because they secluded themselves in the church. So people didn’t know what they were doing. When they did come out it shocked everyone. 2. What is a chanson? A chanson is a French song. 3. What is the song "Five Knacks for Ladies" about? What type of song is it? The song is saying that

Physics 2006 (Compartment Delhi) General Instructions: 1. All questions are compulsory. 2. There is no overall choice. However‚ an internal choice has been pro vided in one question of two marks‚ one question of three marks and all three questions of five marks. You have to attempt only one of the choices in such questions. 3. Question numbers 1 to 5 are very short answer type questions‚ carrying one mark each. 4. Question numbers 6 to 12 are short answer type questions‚ carrying two marks

The purpose of this experiment is to use the ballistic pendulum to determine the initial velocity of a projectile using conservation of momentum and conservation of energy as well as motion of projectiles. Carbon Paper Meter Stick Ballistic Pendulum In this experiment a steel ball will be shot into the bob of a pendulum and the height‚ h‚ to which the pendulum bob moves‚ as shown in Figure 1‚ will determine the initial

Kristen Magliola 9/9/13 BIO: 414L Lab Report: SOC Medium I. Purpose: To make liquid and solid media for microbial growth II. Background: There are four different types of media used to grow microbes. They consist of Enriched media‚ Nutrient media‚ Selective media‚ and differential media. Enriched media is a growth media supplemented with complex biological molecules. This type of media is used for blood‚ coagulated blood‚ amino acids‚ etc. Nutrient media provides nutrients necessary
