As you discussed in this unit’s Discussion Board, survey research is one of the most common ways of collecting data. However, not all survey research is created equal. In this activity, your task is to collect at least 5 different examples of surveys used by local police agencies. Using these examples, write a 4-page report … Read more

For this assessment, develop your own nurse educator philosophy statement. Identify your beliefs and values regarding the adult learner, learning environment, and teaching strategies and applicable learning theories that you will use as an educator. Address how this philosophy will guide you in the tripartite roles of a nurse educator—how it will guide your teaching, … Read more

The sticky cinquefoil (Potentilla glandulosa) is a small, deciduous plant with bright yellow flowers that lives throughout the American West, and its leaf phenotype can vary depending on environmental conditions. Inland, where there are dramatic seasonal temperature swings and unpredictable droughts, plants shed their large “summer leaves” in autumn when the temperature begins to drop. … Read more

The first angiosperms may originally have been small, treelike plants in tropical regions, but eventually they began diversifying rapidly into other habitats where early gymnosperms flourished. South African botanist William Bond proposed the “slow seedling” hypothesis to help explain this evolutionary change, and botanists continue to refine it. The hypothesis proposes that angiosperms were able … Read more

Concerns about global climate change and the greenhouse effect center on rising levels of greenhouse gases, including atmospheric carbon dioxide. Plants use CO2 for photosynthesis, and laboratory studies suggest that increased CO2 levels could cause a rise in photosynthetic activity. However, as one environmentalist noted, “What plants do in environmental chambers may not happen in nature, where … Read more

Botanists estimate that half or more of angiosperm species may be polyploids that arose initially through hybridization. Polyploidy—having more than a diploid set of the parental chromosomes—can result from nondisjunction of homologous chromosomes during meiosis, or when cytokinesis fails to occur in a dividing cell. Hybridization is the successful mating of individuals from two different … Read more

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
