"Ward's Phenomena"

This organism is commonly recovered from soil and water. As normal intestinal flora, it can also usually be found in sewage.

Yeast strains are ideal for genetic study because they are easy to grow and maintain, their life cycle is complete in approximately one week, and you can arrest different stages of the life cycle by growing it on different types of media.

Teach your students about the complete metamorphosis of an insect with these mealworms.

Observe the differences between common mold types
