D)The bulbs were a sugar sink, so water flowed into them and out the roots, washing material from the bulb into the soil.

B)Circadian rhythms occur with or without external stimuli. C)Biological clocks are strongly influenced by external temperatures. D)Movement of plants long distances very quickly induces a kind of plant "jet lag." Q2) One experiment in phototropism involved cutting off the tips of grass seedlings before exposing them to light from one side. The decapitated seedlings did not bend toward the light.

C)a foil cover over the tip of the seedlings would cause them to bend. D)hormones are produced in all parts of the plant. Q3) A plant will only flower if the night length is longer than 14 hours.

Sample Questions Q1) Many rats were tested for their ability to learn to navigate a maze. The average number of errors, for a total of 14 trials, was 64 per rat. The rats that made the fewest errors were bred to each other, and the offspring were tested in a similar way. This process was repeated for seven generations, at which point the average number of errors for 14 trials was 36. This experiment demonstrates that A)learned behavior cannot be inherited. B)maze-learning ability has a genetic basis. C)maze-learning ability depends mainly on early contact with adept parents. D)natural selection has a role in the evolution of fixed action patterns but not in the evolution of behavior involving learning. Q2) A big difference between social learning and imprinting is that A)imprinting does not involve a reward. B)imprinting can only take place among members of the same species. C)social learning has a primarily genetic basis. D)social learning is not limited to a sensitive period. To view all questions and flashcards with answers, click on the resource link above.

Sample Questions Q1) Suppose that scientists who study predator-prey relationships notice that over a 50-year span, new color patterns evolve in the stonefly nymphs such that they are better able to blend into the colors of a streambed. What would be a logical and reasonable question that the scientists could investigate in relation to their observations and their knowledge of predator-prey relationships? A)As the color pattern changes in nymphs developed, was there also a change in the color of the sand of the streambeds on which the nymphs molted? B)As the color pattern changes in nymphs developed, was there an increase in the fish population size? C)As the color pattern changes in nymphs developed, was there a decrease in the phosphorus concentration in the stream water? D)As the color pattern changes in nymphs developed, did the fish eat a greater number of nymphs? Q2) Denitrifying bacteria convert ________ to ________.
