Natural selection: Camels live in dry, sandy deserts.  They have extremely long eyelashes to keep the sand out of their eyes.  Like you practiced in the “synthesis” portion of Homework #2, provide a logical and detailed explanation of how, across generations, a population of camels with very long eyelashes evolved from an ancestral population with normal-length eyelashes due to the process of natural selection.  Apply and define relevant vocabulary.   [Note: Unlike in Homework #2, here you do not need to list the 4 criteria first, just provide the “synthesis” part of the explanation. Your explanation should be clear, complete, and logical so that someone who does not already understand natural selection would be able to understand the process by which long eyelashes evolved in camels.)

A pendulum, shown here, is swinging back and forth without any friction in the system. Image Description A diagram of a pendulum swinging with locations marked. Point A is when the pendulum is on the far left. Point C is when the pendulum is at the bottom of its arc. Point B is in the middle of point A and point C. Use this pendulum to answer the next two questions.

In the following questions a beginning skier starts standing still at the top of a run. He then starts down the hill speeding up as he goes. When he is going as fast as he wants, he angles his skis (snowplows), keeping his speed constant. Finally, he reaches a flat, level portion of snow at the bottom of this run.
