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

Lab 5 The Diffraction Grating Chinua McDonald Objective: To measure the wavelength of light with a diffraction grating. Theory: The two types of diffraction gratings are the transmission and reflection gratings. They are made by ruling on a piece of glass or metal a number of evenly spaced lines with a fine diamond point. Diffraction phenomena can be analyzed in terms of Huygens’ principle‚ according to which every point on the wave front of a wave should be considered as a source

conducted in order to test the possibility of using amorseco or love grass seeds as a source of flour and to compare the quality of baked products from amorseco flour to those produced from commercial flour in terms of taste‚ texture and smell. B. Statement of the Problem The problem studied is the possibility of having the amorseco seeds as a source of flour. The scientific question answered was: “Can the amorseco seeds produce flour that may be compared to world leading commercial flours in

Purpose: The purpose of this lab was to gain a complete understanding around the rate of cellular respiration within multicellular organisms‚ also to research and understand how to use a CO2. Background: Living systems require free energy and matter to maintain order‚ to reproduce‚ and grow. Energy deficiencies cause disruptions at the population and ecosystem levels as well. 1 mol of H2O produces 1 mol of CO2 through cellular respiration. Autotrophic organisms capture free energy from the environment

indicated by a very pale pink color. To calculate the molarity of NaOH‚ the following equation was used MNaOH x VNaOH = MKHP x VKHP therefore the molarity was .125 M. INTRODUCTION This lab experiment covers the preparation of standard solution and the acid/base titration. The first part of the lab is to prepare a standard solution of Potassium hydrogen per. A standard solution is a solution of known concentration‚ in which it is prepared using exacting techniques to make sure that the molarity

ASSIGNMENT OF SEED PROCESSING ON GRAVITY SEPARATOR AND COLOR SORTER Submitted to Dr. Yadvika Submitted by Aman Dhillon 2009AE05BIV Color Sorter Separation Principle Electronic color sorters separate seed by differences in color. Each seed is viewed and electronically compared with a pre-selected color background‚ and accepted or rejected. The color sorter can also separate off-color mud balls‚ other seed kinds and discolored or other-variety crop seed whose color is different from that

has on seed germination and after performing this experiment is can be concluded that acid rain has a negative effect on seed germination. When seeds are soaked in an acidic solution the process of germination slows. Acidic solutions‚ while do slow growth of a seed‚ they do not kill the seed. A seed can be dormant for a majority of its lifespan‚ seeds watered with acid solutions stayed in a dormant condition. For example‚ trial three (3) part one (1) and two (2) both experienced germination. Whereas

2 March 2012 Period 4 Professional Writing Sample See the Forest for the Trees As the great poet Robert Louis Stevenson once said‚ “Don’t judge each day by the harvest you reap but by the seeds you plant.” I believe this quote says that if you put all your attention on planting you will have overflowing crops‚ but if you focus on the crops‚ you might lose sight of how the crops came about. In the end it’s not about enjoying the results‚ it’s about enjoying how the things started. The quote
