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

Post-Lab Questions 1. Using the information provided in the Introduction and your observations from Part 1‚ hypothesize as to the type of electrolyte the following solutions would be. Justify the hypothesis from a chemical standpoint. a. Aqueous Sodium Hydroxide—NaOH (aq) is a very strong base‚ which will completely disassociate into Na+ and OH- ions‚ which would make it a very strong electrolyte. Chemical reaction of the disassociation of Sodium Hydroxide: NaOH (aq)Na+ (aq)+ OH-(aq)

simple mechanisms used to convert rotary motion into oscillating linear motion and vice-versa. The first of these is the slider-crank - a mechanism widely used in engines to convert the linear thrust of the pistons into useful rotary motion. In this lab we will measure the acceleration of the piston of a lawn mower engine at various speeds. The results exemplify a simple relation between speed and acceleration for kinematically restricted motions‚ which will discover. An adjustable slider-crank apparatus

the 70’s 80’s and 90’s Computer technology took a great leap in development during the 70’s when schools‚ businesses‚ and universities began to use computers. The 70’s would have to be the beginning of the technology of computers‚ as we know it today. The personal computer became big in the 80’s. Now computers are being updated daily‚ if not hourly. During the 70’s computers and computer use began to become known by everyone. This period was a time for development and improvement. The 70’s was where

mass of the beans Dependent variable: the different types of beans Control: The beans Purpose: The purpose of the lab is to find equal measurement of each type of bean. After you find the mass of each bean you need to find the relative mass of each bean. The navy bean will have the smallest relative mass. You will need to wear safety goggles and a lab apron and wash hands after the lab is finished. If you drop any beans pick them up immediately to prevent anyone from slipping. Materials Safety goggles

Andrew Auriemma Professor Walwyn Marketing The marking mix is everything a company does to the demand for its products. There are four groups in which this can be done‚ price‚ product‚ place‚ and promotion. Product is what the company is offering. An example of this is MacBook. The product comes with a laptop‚ which has everything from keys to a mouse keypad. It also comes with a charger. There are all-different types of MacBook’s and most come with a warranty. Then there is price. Price comes
