Cell Reproduction - A.L.E.
Settings
Welcome to the E. L. E. (Electronic Learning Environment) for Advanced Biology course. This active learning exercise will cover cell cycle, mitosis, and meiosis cycles. The cells of all living things grow and multiply through a cycle. I hope this activity will stimulate your thinking of cell growth, repair, and reproduction. You are given an unlimited number of attempts at "cellular reproduction" to increase knowledge and test-taking skills. Each attempt have questions and answers that are randomly sorted. GOOD LUCK!
