Chemistry Of Life Warm Up 1

Welcome to the advanced biology electronic classroom for the 21st century of Mr. John Mitchell. All living things are made of the same basic materials: carbon, hydrogen, oxygen, and nitrogen. This warm up deals with how cells and atoms are related. This warm up will allow you unlimited number of attempts to increase your learning and test-taking skills. As a bonus, each attempt will randomly generate a new question and answers.
