Choose the best answer. Which is NOT a primary use of dams? (a) recreation (b) electricity generation (c) flood control (d) habitat restoration

Use the matrix capabilities of a graphing utility to find the inverse of the matrix (if it exists).

$$\left[\begin{array}{rrrr} {1} & {-3} & {2} & {-1} \\ {0} & {4} & {-12} & {8} \\ {3} & {0} & {5} & {-2} \\ {0} & {-3} & {9} & {-6} \end{array}\right]$$

Choose the best answer. Drought conditions (a) can result in increased nutrient cycling. (b) decrease the severity of flooding. (c) are rarely affected by human activities. (d) cause increased erosion.

Choose the best answer. Population growth using the exponential growth model (a) increases at a constant rate. (b) has an increasing intrinsic growth rate. (c) represents ideal conditions that rarely occur in natural populations. (d) incorporates the carrying capacity of the population.

Choose the best answer. Mycorrhizal fungi are commonly found attached to plant roots. The fungi are more efficient than plants at extracting nutrients from the soil. In exchange for nutrients, plants provide the fungi with sugars made through photosynthesis. However, when nutrients in the soil are abundant, researchers have found that plant growth increases if mycorrhizal fungi are removed. This phenomenon suggests that (a) mycorrhizae have switched from being mutualists to parasites. (b) mycorrhizae have switched from being mutualists to predators. (c) mycorrhizae have switched from being mutualists to commensalists. (d) mycorrhizae have ceased to act as a keystone species.

A formula used to help determine the speed of a car from its skid marks is $S=\sqrt{30 D f}$ where S is the least possible speed (in miles per hour) of the car before its brakes are applied, D is the length of the car’s skid marks (in feet), and f is the drag factor of the road surface. Find the least possible speed of the car for the given conditions. Skid marks: 60 feet, drag factor: 0.90.

Choose the best answer. Which constitutes baseline data on the effects of humans on natural ecosystems? (a) concentrations of atmospheric $\mathrm{CO}_{2}$ before humans existed (b) current rates of species extinction (c) global rate of freshwater consumption from 1900 to 2010 (d) average plant productivity on a remote island uninhabited by humans
