explanations will be provided in the test questions themselves. Bring a calculator to the exam, capable
of performing squares and square roots. DO NOT BRING ANY DEVICE CAPABLE OF
DISPLAYING WORDS OR LETTERS!!!! YOU WILL NOT BE ALLOWED TO USE IT!!!!
NUMERICAL DISPLAY ONLY!!!!
YOU WILL BE RESPONSIBLE TO:
1. Use the Hardy-Weinberg allelic and/or genotypic equations to find the genetic structure of a
population, given allelic or genotypic data concerning that population.
2. Be able to utilize geologic time scales to determine the approximate ages of fossils and of rock strata.
You will be provided with a rock strata representation and a geological time scale sheet with which to
work.
3. Be able to utilize data concerning the half life of radioisotopes in order to calculate the age of a
sample, or the percentage of original radioisotope remaining in a sample.
4. Be able to identify by name any indicated part or structure, of any organism or tissue, in any pictorial
