2. Light skin is an evolutionary adaptation that evolved in our human ancestors who lived:

A. along equatorial regions with direct sunlight, and it protected the body against too much sun exposure and overproduction of Vitamin D
B. in swamp habitats with extreme humidity, and it protected the body against overheating
C. in northern latitudes, and it allowed the body to absorb enough sunlight to manufacture adequate amounts of Vitamin D
D. in icy conditions and protected the body from developing frost bite
E. along wooded riparian (river) habitats and allowed the body to absorb enough sunlight in a shaded environment

3. Early on in human evolution, natural selection favored dark skin closest to the equator, where sunlight and exposure to UV light is most intense.

Bogs are areas with acidic soils in which carnivorous plants can often be found preying on insects. If insects are a good source of nitrogen, why don ?t more plants in all other ecosystems adopt carnivorous habits?

A. plants in other habitats obtain nitrogen from bacteria in their root nodules.
B. insects in other habitats do not contain as much nitrogen.
C. insects are more mobile and hard to catch in non-swampy areas.

D. it is more energy efficient to absorb nitrogen from soils that are not deficient of nitrogen

Millions of acres of spruce trees have been killed due an explosive increase in spruce bark beetles in recent years, and scientists suggest global warming as the underlining cause. How could this be related to global warming?

A. longer, warmer seasons have resulted in increased beetle populations.
B. spruce is more susceptible to beetles at high temperatures.
C. global warming is the cause of acid rain, and the trees are being weakened.

D. spruce bark beetles did not attack spruce trees until the Industrial Revolution.

In sustainable farming practices involving crop rotation, should the land be covered at all times with plant material?

A. No, the decaying foliage harbors disease.
B. No, it should be tilled under to add nutrients to the soil.
C. yes, because this minimizes the breeding of pests in soil
D. yes, this lessens erosion of topsoil.

Please help! Also, explain answers if you can. Thanks!
