Biology Final Exam Review

Before beginning an experiment, the teacher reminds the students how to use the safety equipment shown below. Which of the following pieces of safety equipment is most likely needed for this lab?

• helmet

• goggles

• heavy gloves

• fire extinguisher

Which statement about evolution is correct?

• Individuals can change their behavior, so individuals can evolve.

• Evolution applies to genetic changes over time, so depending on the lifespan of the organism, they may have time to evolve.

• Evolution applies to genetic changes over time in an entire population.

• Populations of organisms do not change, so if a variation in the organism's genetic makeup occurs, a new population is started.

Many acres in a large woodland area are sold to a new home development company who begins building a new neighborhood of houses as well as paving new roads. How will this new housing development most likely affect the ecosystem?

• The native species will be forced to relocate due to the loss of habitat.

• The buildings and roads will remove producers resulting in a reduction in the energy available to the native species.

• The increase in automobile traffic will result in pollution that will make it harder for the native species to survive.

• All of the above.

Wolves are affecting local ranchers who then seek to hunt and eradicate the wolves in the area. What will most likely happen to the ecosystem if the wolves are completely removed?

• The ecosystem will become more stable because there are fewer predators

• The ecosystem will become less stable because there are fewer predators

• The ecosystem will become more stable because another predator will now be favored by these conditions

• The ecosystem will become less stable because in the immediate future the wolves' prey will overpopulate.
