In the experiment studying bioluminescence and the predation of copepods by fish, a control group of jars with bioluminescent dinoflagellates experienced a higher predation rate of copepods by stickleback fish than in the jars with nonbioluminescent dinoflagellates. This provided significant evidence that
A. All of the answer choices are correct. B. natural selection has favored the survival of dinoflagellates that can emit light in flashes when disturbed. C. copepods that would eat dinoflagellates benefit from fleeing when the protists bioluminesce. D. dinoflagellates can avoid being eaten by increasing the flashing, and attracting predators to eat the copepods near them. E. natural selection has favored the survival of copepods that move rapidly away from flashing bioluminescent dinoflagellates.
In the late 1920s, a mutation occurred in many silver fox farms around the world. The fox farms that sold expensive
furs were proud of the quality of their furs, and each advertised that it had the best, purest breed of all the fox farms. The new mutations produced a "platinum" coat pattern that was commercially desirable, so the farms crossed them to get more. The results of their breeding experiments were as follows: (1) silver ´ silver >>> all silver offspring; (2) silver ´ platinum >>> equal numbers of silver and platinum; (3) platinum ´ platinum >>> two platinum for each silver offspring. Explain. What will be an ideal response?
The Hardy-Weinberg equilibrium is based on a number of assumptions. Which of the following is not one of these assumptions?
