Choice test

A fermented-egg product (EEP), patented as an attractive bait for synanthropic flies, has been shown to be attractive to coyotes and repeUent to deer (79). Its components are variable, with relative concentrations of 77% fatty acids, 13% bases, and 10% (primarily) neutrals composed of at least 54 volatiles such as ethyl esters, dimethyl disulfide, and 2-mercaptoethanol. Synthetic formulations have been evaluated to find a replacement for a patented fermented-egg protein product that attracts coyotes and repels deer. Ten aUphatic acids (C-2 to C-8), four amines (pentyl, hexyl, heptyl, and trimethyl), dimethyl disulfide, 2-mercaptoethanol, and 54 more volatiles (C-1 to C-5 esters of C-1 to C-8 acids) have been tested as synthetic fermented egg (SEE) (80) in approximately the same proportions that are present in EEP. Weathering was a problem that caused decreased efficacy, which suggests trials of controUed-release formulations. Eourteen repeUents have been examined against white-taU deer in Peimsylvania in choice tests when treated onto sheUed com (81). 

Testing knowledge acquisition interviews and/or the discussion of case studies can be conducted on a fairly informal, non-threatening basis. Whilst exams, open-book tests and multiple-choice tests are an option, they appear far too stringent within a mentoring context. 

MHC genotype has also been found to influence kin recognition, in the context of maternal behaviour in mice. Female mice are more likely to form communal nests with kin of MHC-similar genotype, minimising the delivery of maternal resources to genetically unrelated individuals (Manning, Wakeland and Potts 1992). Furthermore, if mouse pups have become scattered from the nest, females preferentially retrieve pups of similar MHC type to themselves (Yamazaki, Beauchamp, Curran and Boyse 2000). The pups themselves appear to be able to use MHC-related cues to learn the odour of their mother and siblings, as revealed by a preference for odours of maternal MHC-type in a choice test (Yamazaki et al. 2000). 

For a socially living individual it is of high relevance to be aware of the emotional state of one s conspecifics. It is a fairly well-known phenomenon that animals of different species react to odour emitted by another animal which is under stressful conditions. This led several researchers to the question of whether emotional state in humans can influence their body odour. This possibility was first tested by Chen and Haviland-Jones (2000), who asked their subjects to wear armpit pads while watching 13 min excerpts from a comedy or a fearful movie. Most of them watched both excerpts. Subsequently three and six choice tests were presented to raters who were instructed to pick the sample that smelled of people when they are happy or...

After dominance is established, the dominant male occupies a "preferred" large shelter which becomes a focus of social interactions. Mature, premolt females visit frequently (31,32). For cohabitation and subsequent mating, females in naturalistic aquaria chose the dominant male over subdominants (31). In choice tests females prefer larger dominant males (23). Females make these behavioral decisions both from a distance and at the shelter entrance. Discrimination by females is lost when males are catheterized and can be regained when that male s urine is artificially released near the male (23). Thus, male urine cues for female choice are implied but have not been identified. 

This is where you get a chance to practice your multiple-choice test-taking skills. Take it as a test, within the specified time frame. We have attempted to word the questions as closely as possible to the way the questions will be worded on the AP Exam.

When working on a multiple-choice test, the answer selection must be a multiple of the ratio given for the item in question. For example, in the preceding flower example, the number of pink flowers must be a multiple of 15. Eliminate any answer choices that are not a multiple of 15. 

Before proceeding, make an estimate of the answer. This will help to balance your tendency to avoid the check at the end of the solution process. If your solution is not close to your estimation, reconsider your solution. In addition, read over the answer choices if it is a multiple-choice test. Often, you can use the answer choices and a strategy such as guess and check to... 

Throughout the course of this book, we have looked at many word problems. Several problems involving distance and speed, percents, simple interest, and ratio and proportions have been reviewed. One other type of word problem not reviewed previously is consecutive integer problems. These problems are relatively easy to solve on multiple-choice tests.

Red-sided garter snakes from different regions of Manitoba, Canada show signs of isolation by chemical cues. In choice tests, males from a hiber-naculum (overwintering den) in central Manitoba preferred females from their own population to females from western Manitoba. Males from western Manitoba showed no preference. When confronted with experimental trails, males made the same choices. This demonstrated that a chemical factor is involved. Furthermore, the sexual attractiveness pheromone of females, a series of ty-9-cis-unsaturated methyl ketones, varies between the populations. Specifically, the... 

Finally, choice tests were initiated both at Lilly and at Bowling Green on the acceptability and efficacy of this material as a rodenticideC14) All laboratory tests indicated that compound 4 was readily accepted by rats and mice (Appendix V). 

It was also essential to determine how effective bromethalin was against warfarin-resistant rats and mice. Such animals, whose resistance to anticoagulants had been determined by World Health Organization tests,(17) were subjected to a standard EPA choice feeding efficacy test with bromethalin at 0.005% in the treated diet. The results indicate (Appendix 6) that 90% of the animals were killed and that consumption patterns were similar to those observed in other choice tests.

Most exams are multiple-choice tests of the sort you have often encountered in school. You get an exam book and an answer sheet where you have to fill in little circles (bubbles) or squares with a number 2 pencil. 

Whenever you do arithmetic with fractions, reduce your answer. On a multiple-choice test, don t panic if your answer isn t listed. Try to reduce it and then compare it to the choices. Reduce the following fractions to lowest terms. The answers appear at the end of this section on page 162.
