Teach your students about the complete metamorphosis of an insect with these mealworms.Live specimens are used for a wide variety of studies including studying the physiological effects of drugs on a specimens heartbeat and temperature on metabolism, the locomotion of microscopic organisms, and studying plant respiration, photosynthesis, plosmolysis, and more.
