I have a couple of subspecies of Stapelia hirsuta, or starfish flowers, currently growing in my backyard. Different flowers attract pollinators in different ways. Moths are generally attracted to white, fragrant blossoms. Bees like a nice landing pad with nectar lines to guide them in. This flower attracts flies. It does this by emitting a foul odor, much like that of rotting flesh. This nauseating smell permeates the air within a five foot radius of the plant. It mimics the smell of rotting flesh so well that flies have deposited eggs in this flower. The picture on the right shows the larvae. Some are wriggling about, while others still seem to be encased. I doubt the larvae will survive as there is no real meat on which to feast on. Silly flies.
Update: Here's what it looked like the next day. The flower has wilted and the larvae are strewn about and dead.
Biotechnology 2 performed their dye electrophoresis today, here are the before and after pictures. The dye migrated toward the positive electrode, indicating that the dye itself is negative. The heavier blue dye did not travel as much as the yellow, indicating that it is heavier than the yellow dye.
In this forensic simulation we tested "stomach contents" to determine what our victim ate last. Here are the results for Biology's "Murder and a Meal" lab, from left to right:
Lipid test was positive, indicated by the red stained fat molecules floating at the top.
Glucose test was positive, the indicator went from royal blue to a pale green color.
Starch test was positive, indicator changed from dark brown to blackish-purple.
