When Simon hallucinates and takes to the lord of the flies. He realizes the beast is inside them.
What does Simons comment about Piggy helping to build the fire tell us about him in Lord of the Flies?
Why does ice often form on the leading edges of an airplanes' wings when it flies through clouds at high altitudes?
Because, it is cold at higher altitudes. Air hits the leading edge and flows through the upper and lower part of wings. Because relative velocity is zero, then there are stagnation points in leading edges. Water droplets presented in clouds cannot flee from these stagnation points, as it's density is more than air. And droplets stick to the leading edge and freeze.
Drosophila melanogaster (Fruit loving yellow underbelly flies) are the best examined flies in the world. They have been critical to our understanding of genetics and the actions of genes on morphology and mutations. They were the first insects to be taken into space by the shuttle Columbia whichregrettably burnt up on reentry due to a hole in the leading edge of a wing. Some flies survived the accident when found in the debris.
