Sexual reproduction results in an increase in genetic diversity because:
A. during prophase I, genes that are paternally and maternally derived are recombined on the chromosomes so that the gametes have chromosomes that are different from the parents' chromosomes. B. during metaphase I, the bivalents line up in a random orientation so that gametes inherit a random set of maternally and paternally derived chromosomes. C. during fertilization, the gametes that fuse are random so that a large number of chromosomal combinations are possible in the new organism. D. of both recombination during prophase I and random orientation of bivalents during metaphase I. E. All of these choices are correct.
A moth species is known for its unusual flying behavior, which includes sudden vertical drops and horizontal zigzags. Not much is known about the cause of this behavior. What could you study to better understand the proximate basis of this behavior? (Check all that apply)
Lepidopterans (moths and butterflies) sometimes have specialized flying behaviors. Some moths have the ability to do sudden vertical drops when they detect bat sonar, to avoid being eaten. Other species use special flying techniques to attract a mate. When biologists talk about the "cause" of a behavior, they may be referring to two different things. The proximate cause is the sequence of physiological events that lead to the behavior in an individual. The ultimate cause is the adaptive benefit to the animal that allowed natural selection to sculpt the behavior over evolutionary time. Understanding both the proximate and ultimate basis of behavior is important, and different types of biologists may focus on each. _____ brain structure _____ flying behavior in related species _____ hormones _____ mating behavior _____ physiology _____ predation _____ sensory organs _____ wing muscle development Clarify question: What is the key concept addressed by the question? What type of thinking is required? Gather Content: What do you already know about proximate causes of a behavior? What other information is related to the question? Choose Answer: Given what you now know, what information is most likely to produce the correct answer? Reflection on Process: Did your problem-solving process lead you to the correct answer? If not, where did the process break down or lead you astray? How can you revise your approach to produce a more desirable result?
