AP BIOLOGY Lab 5 Cellular Respiration Objective: To calculate the rate of CR from the data. To then relate gas production to respiration rate. Then test the rate of CR in germinating versus non-germinating seeds in a controlled experiment and then test the effect of temperature on the rate of CR in the germinating versus non-germinated seeds in a controlled experiment. Analysis: 1. The CR is higher in the germinating peas in the cold water rather than in the beads or non-germinating peas

anatomy and physiology lab 1. What are some differences between Judy and Mariah that might make Judy more "at risk" for skin? cancer than Mariah?Judy had a pasty white skin. Therefore‚ her skin had less melanin than Mariah who had black hair and more melanin and are more protected against the uv rays of sun. 2. What observations did Judy make concerning her mole? Her mole changed shaped and turned bigger and its side were jagged. The middle was purplish-black and its edge were darker than

Melissa Cavanaugh Lab: Tuesdays at 1pm Enzyme Kinetics Lab Introduction: Enzymes are proteins that will catalyze reactions to make the rate of the reaction occur faster than it would without. It can also make the reaction occur in the first place. Tyrosinase is an enzyme that has a variety of functions and activities. It produces pigments like melanin and others that would be apparent when a fruit is cut in half and it browns. (Bien-etre 3).There is that one function that stands out and the enzyme

The refraction of light lab used common materials to examine the process of the refraction of light. The title of this lab is exactly what occurs throughout the four different experiments. All four parts of this lab use prior knowledge to observe the complex concept of refraction. Refraction is the bending of a light when it enters a medium where the speed of light is different. When light enters through the glass and water the speed of light becomes decreased. This is due to the density of water

Lab Report: Scientific Method Your Name: Alyssa Melincoff Purpose of this Lab What is the goal of this lab? What question is it trying to answer‚ or what problem is it trying to explain? To find out how table salt affects the boiling temperature of water. Hypothesis After reading the lab instructions - but before starting the lab - record your best “educated guess” about what will happen in the experiment. What hypothesis can you generate about the effect of adding salt to water? Adding

Name:Date:Professor: Converting Decimal to Binary and Binary to Decimal (20 points) Instructions for the Binary Conversion Exercise: NOTE! LOG ON TO SKILLSOFT TO DOWNLOAD THE LAB INSTRUCTIONS AND START THE LAB. In computers binary code is the language that communicated between applications. Binary Code is a coding system using only digits 0 and 1 to represent a letter‚ digit or other characters in a computer. It is hard to imagine that huge and hard calculations are done on computers applications

Objective: The objective of the lab is to separate the caffeine samples we are using‚ using thin layer chromatography. The solvent we are using for the separation is 3:1 mixture of Chloroform and Acetone. Principle: Thin layer chromatography (TLC) is an important technique that is useful for separating organic compounds. TLC is often used to monitor the progress of organic reactions and to check the purity of products. Separations in Thin layer chromatography involve distributing a mixture of

Biology 20 IB Design Lab Does increasing or decreasing the ph level of a 3% concentration H2O2 (l) solution affect the amount of oxygen released between 15.0ml of the solution and a 5g sample of liver? The reaction is measured by the difference in mass of a balloon that is used to capture the amount of gas released by the catalase enzyme found in liver reacting with a basified 3% H2O2 (l) and an acidified 3% H2O2 (l) . Chemical reactions occur when two or more molecules interact and the molecules

Title: The Mass of Quartz Purpose: To determine the density slope for water and alcohol and apply the understanding to determine the volume of a quartz sample without measuring the volume or calculating it. Hypothesis: The hypothesis of this lab was by using the density of alcohol we could calculate the density of a quartz samples. Controls and Variables: Independent variable: Volume of water and alcohol Dependent variable: The weight of the liquid or solid Controls: The volume of
