Cell Reproduction: Warm Up 2
Welcome to the electronic frontier of the 21st century for science education. This is the first of two biology warm ups (bell ringers) for this topic of cellular reproduction. The cells of all living things grow and multiply through a cycle that's made up of six phases. This warm up provides an unlimited number of attempts to improve your learning and test-taking skills. As a bonus, each attempt yields a new question and answers.
