It's Genetic! Day 3

Today in Biology Lab, the girls looked at how appetite is controlled by genes and the environment in C. elegans--little tiny worms! Did you know that these worms LOVE the smell of buttered popcorn?! That smell is actually a chemical called diacetyl. At first, the girls put worms at one side of their petri dishes and watched the worms wiggle their way towards the smell that was located at the other end of the dishes. They, then, were given two different samples of these worms in two other petri dishes: one wild (natural) sample and one mutated sample. The girls had to use their knowledge from the first sample and decide which sample was the wild sample and which was the mutated sample. Look at what the girls were looking at through their microscopes!
