Answer the following statements true (T) or false (F)
1. The North American Mohave desert is located on the downwind side of the Sierra Nevada mountain range, which creates a rain shadow.
2. The abyssal zone has the highest productivity and biodiversity in the ocean, partially because it is well-oxygenated and stable in temperature.
3. Humans were largely unaware of the medicinal use of many plants until the advent of modern pharmaceutical science.
4. Scientists have already observed significant range shifts as a result of climate change.
5. Political and economic pressures typically make habitat preserves larger, making it easier to set aside areas large enough to maintain biodiversity.
1. True
This statement is true. The North American Mohave desert is located on the downwind side of the Sierra Nevada mountain range, which creates a rain shadow.
2. False
This statement is false. The neritic zone has the highest productivity and biodiversity in the ocean, partially because it is well-oxygenated and stable in temperature.
3. False
This statement is false. Humans have long been aware of the medicinal use of many plants, such as in Europe, where people catalogued this knowledge in herbals—books that identify plants and their uses.
4. True
This statement is true. Scientists have already observed significant range shifts as a result of climate change. For example, some European bird species ranges have already shifted an average of 91 kilometers north.
5. False
This statement is false. Political and economic pressures typically make habitat preserves smaller, making it difficult to set aside areas large enough to maintain biodiversity.

In its youth, a pet parrot was owned by someone who kept the wings clipped and never allowed it to fly. Later in life, the new owner let the feathers grow and let the parrot fly around the house. But the parrot kept knocking over lamps and crashing into walls. "Wow," said the owner, "I guess parrots are just too clumsy to fly around a house without destroying everything." What is an alternative explanation?
A. In nature, parrots have much more room to fly, and do not have to navigate around delicate home decor. B. Since the parrot was not able to practice flying during the critical period for flight development, the brain circuits for accurate flying were not able to develop. C. The parrot just needs more practice flying -- although it did not get to fly when young, this should not affect later ability. D. The critical period for flying development in the brain has just now begun with the bird's first attempt. In a few weeks the critical period will end, so it must practice during this time.
