Multiple choice!

the figure below shows smaller and larger beaks in a population of finches. one group of birds has a short, parrotlike beak and another group has a long, narrow beak. what process has probably occurred?

a. directional selection
b. stabilizing selection
c. genetic drift
d. disruptive selection

the answer is disruptive selections so option D.

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.
