The Hawaiian archipelago (collection of islands) is way out in the Pacific Ocean.  This chain of islands was created by a volcanic “hotspot” that formed each island over many millions of years.  Soon after the newest island of Hawaii (“the big island”) rose above the sea surface (somewhat less than 1 million years ago) and organisms colonized the island, the evolution of life on this new island should have been most strongly influenced by:

Large male horned dung beetles, Onthophagus taurus, use their horns as weapons in fights with rival males over ownership of breeding tunnels containing females. Females excavate (dig) tunnels beneath fresh dung (manure) piles where they mate with the males, and then lay their eggs. The use of the horns by the males in contest for the breeding tunnels is an example of: I:   intersexual selectionII:  intrasexual selectionIII: sexual selection

Phenylthiocarbamide (PTC) is a compound that tastes either very bitter or is tasteless, depending on the person’s genetic makeup.  Suppose 64 percent of people living in a remote, isolated mountain village can taste PTC and must, therefore, have at least one copy of the dominant PTC taster allele. If this population conforms to Hardy-Weinberg expectations for this gene, what percentage of the population must be heterozygous for this trait?

A zombie apocalypse wipes out almost the entire human species before the zombie threat is eliminated. Only a group of 100 people who were at a family reunion on an uninhabited island survived. They returned to the mainland completely unaware of what had happened to everyone. Certain traits will have been lost from the gene pool forever. This loss of diversity in a reduced population is called 

Darwin and Wallace’s theory of evolution by natural selection was revolutionary because it:

True or False. A test administered to a group of 5-year-old children classifies 10 percent as “at risk” for learning difficulties. By measuring the extent to which the test correctly predicted classification at the end of the third grade, you determine the predictive power of the test.

Maurice is a school psychologist who used to be optimistic and very proactive at work. Recently, he has become very cynical toward his clients and “blames the victims” for their own difficulties. Maurice is likely experiencing which form of the developmental model of burnout?

The American Psychological Association’s guidelines for working with ethnically, linguistically, and culturally diverse populations note that psychologists:

Jane is a 9 year, 5 month old fourth grade student who was referred to the Child Study Team by her father due to concerns for her inability to maintain her attention and focus. Which of the following checklists or data collection would be least helpful in obtaining additional information on Jane’s attentional skills?

Ryder is trying to follow the American Psychological Association’s ethical guidelines for working with ethnically, linguistically, and culturally diverse populations. His new assignment is with a client who requests that Ryder speak in French. Ryder does not speak French. What is Ryder to do?
