Lab Quiz 1
Base your answers to questions 1 through 5 on the information below and on your knowledge of
biology.
An investigation was performed to estimate the amount of absorption of different
wavelengths (nanometers) of light by a photosynthetic organism. The following data were
collected: 550 nanometers. 40% absorption; 450 nanometers, 85% absorption; 650
nanometers. 70% absorption; 500 nanometers, 60% absorption; 600 nanometers. 50%
absorption.
1. Complete both columns of the Data Table so that the nanometer values are increasing. [1]
