S8 - End of Unit 1 Test

This document is an end-of-unit test for a science unit on respiration. It contains 3 multiple choice and short answer questions that assess students' understanding of key concepts like: 1) The functions of red blood cells and white blood cells, and another component of blood and its function. 2) The reactants and products of aerobic respiration and where it occurs in cells. 3) The parts of the respiratory system modeled, including the trachea, rib cage, and diaphragm, and how the diaphragm facilitates breathing.
