You are a drop of water that has fallen from the sky during a thunderstorm. Compose an autobiography of your life. Focus on your feelings as the matter in your body changed states. Describe a time when you were frozen into a solid and another instance when you were heated to evaporate into a gas. Where were you when these changes occurred? How did your atoms and molecules react to the changes in state?Discuss their movement. Include as many chemistry vocabulary words as possible in your story.

Read the following scenario to answer the following question. in some zoos, rare crosses between a male lion and a female tiger have produced hybrid offspring called "ligers." male ligers are sterile but some female ligers are fertile. in the wild, lion and tiger ranges do not naturally overlap, making such a cross unlikely. furthermore, the solitary behavior of tigers and the social organizations of lions create behavioral differences. applying the biological species concept, the sterility of ligers reveals that a. lions are probably a subspecies of tigers b. tigers and lions are the same species c. a new species called "ligers" is forming d. tigers and lions are separate species

Advances in technology have enabled scientists and researchers to better study the evolutionary relationships between species
