Although hummingbirds and house flies both use wings to fly, this similarity is not based upon closely shared ancestry, but rather on evolution and adaptation as a result of survival and reproduction in a given environment. The term best describing such a phenomenon is:

If organisms A, B, and C belong to the same class but to different orders and if organisms C, D, and E belong to the same order but to different families, which of the following pairs of organisms would be expected to show the greatest degree of structural homology (i.e. most closely related)?

Both animals and fungi are heterotrophic. The fact below that distinguishes animal heterotrophy from fungal heterotrophy is that only animals derive their nutrition from…

Extra credit: List three “problems” that land-dwelling organisms have to deal with, then list the adaptations that plants AND animals have acquired to deal with these “problems”. Example: Problem-Dry environment leading to less nutrient absorption Plant adaptation-Roots & root hairs for nutrient absorption in soil Animal adaptation-Intestinal folding with villi & microvilli (increased surface area)

What is the probable sequence in which the following clades of animals originated, from earliest to most recent? 1. Tetrapods 2. Vertebrates 3. Deuterostomes 4. Amniotes 5. Bilaterians

Which of the following BEST distinguishes Primary Disorder etiologies from Personality-Related etiologies as described in Chapter 3?

Evidence indicates that an ancestral finch species from South America arrived on the Galapágos islands and formed many new species, adapting to the diverse environments on the islands. With the evolution of these new bird species on the Galapágos islands, we would expect to find a corresponding…

Spores and seeds have basically the same function…dispersal…but are vastly different because spores _________.

During an evaluation, a voice pathologist performs brief trials of a resonant voice technique and a semi-occluded vocal tract exercise. The patient immediately produces noticeably cleaner, fuller phonation and is surprised by the improvement. This procedure is BEST described as which evaluation component?
