5 Haiti won independence from France in 1825, but had to pay reparations until 1947.

6 More than 75% of energy in Haiti is provided by charcoal.
In 1980, Haiti still had 25% of its forests, as of 2004, only 1.4% of Haiti's forests remained Border between Haiti (deforested area at left) and the Dominican Republic. NASA photo.

12 Sample Exam Questions:
Some organisms have much more DNA than humans do. Does this mean that they can make a greater diversity of proteins than humans can?

13 Sample Exam Questions:
Some organisms have much more DNA than humans do. Does this mean that they can make a greater diversity of proteins than humans can? Why or why not? Not necessarily. They may have more non-coding DNA.

14 Sample Exam Questions:
Both humans and wolves live in groups. How is the advantage gained from forming groups different between humans and wolves?

15 Sample Exam Questions:

17 Sample Exam Questions:
Do you expect more or fewer future human conflicts over resources? Why? Likely more conflicts. Human population is increasing and resources are not. Rain decreases in some areas will lead to greater conflicts. Alt answer: Some areas are experiencing increases in rainfall, and that may diminish conflicts in those areas by making more resources available.

18 Studying Biology: Start with a question. How do we get answers?
For example: How? Why? When? Where? Etc? How do we get answers? Strong Inference presents one method (article on webpage)

The primary function of the giraffes' long neck is not for feeding.

22 They do use their necks for fighting and defense.
