Tiny, thornlike trichomes on leaves are a common plant adaptation to ward off insects. Those trichomes develop very early on, as outgrowths of a seedling’s epidermal cells. Biologists have observed, however, that many mature plants develop more leaf trichomes after the fact, as a response to insect damage. Researchers at the University of Chicago decided … Read more
The fruit fly Drosophila melanogaster can distinguish a large repertoire of odors in the environment. Their response may be to move toward food or away from danger. Moreover, particular odors play an important role in their mating behavior. The olfactory organs of a fruit fly are the antennae and an elongated bulge on the head … Read more
(a) Temperate grassland and chaparral often burn in lightning-induced fires, which stimulate the germination of seeds and regrowth of existing vegetation. Do you think that companies or the government should sell fire insurance to people who build expensive homes in places where periodic fires are virtually inevitable? (b) Boreal forests generally harbor many fewer species … Read more

Mental measurements of young children are often made by giving them blocks and telling them to build a tower as tall as possible. One experiment of block building was repeated a month later, with the times (in seconds) and five pairs of children’ completion times are listed below. Test the claim that there is a … Read more
1. When local calls are made in NYC, 60% go through on the first try, and the rest get a busy signal. (We assume there is no third possibility). Let X=# times a call is actually placed for the call to go through Of course on each try, the call goes through with probability .6. … Read more

Throughout your degree you have been presented with a wealth of scientific information stemming from carefully designed research projects. For scientists to carry out research, they must acquire funds from their own institutions or external agencies, both public and private. In most cases, getting the funding requires submission of a research proposal that clearly outlines … Read more
