Knowing an individual's DNA sequence may be beneficial because:
A. it makes it possible to predict susceptibility
to disease.
B. it makes it possible to predict response to
medications.
C. it makes it possible to predict physical
differences.
D. it makes it possible to predict the
occurrence of a disease.
E. All of the answer options are correct.

The genomes of free-living spirochaetes are larger than those living in animal hosts. Why might this be so?
A. Free-living spirochetes will need genes to code for additional proteins to synthesize or obtain their own food from the environment around them. Parasitic spirochetes obtain nutrients from the animal host, and may not need to move towards those nutrients either. B. The spirochetes in animal hosts are different species entirely. As different species, they would naturally have smaller genomes. C. A smaller genome implies simplicity-the spirochetes living in animal hosts have fewer needs, so they need fewer genes. D. It isn't so-all spirochetes would have the same size genomes, since they're all the same species of microbe.
During inspiration (a.k.a. inhalation) of air into the lung of a mammal
A. the chest cavity has a positive pressure. B. the diaphragm moves upward. C. the diaphragm contracts. D. the rib cage moves down. E. the intercostal muscles relax.
What is an exception to the standard biological species concept used to define a species?
A. Natural interbreeding populations cannot be distinguished using this concept. B. Asexual species cannot be distinguished using this concept. C. Species that coevolved cannot be distinguished using this concept. D. Species that do not resemble one another cannot be distinguished using this concept.
You are interpreting data on a DNA chip or microarray. You expose the chip to a mixture of two cDNA populations: one from cells that were not treated with a glucocorticoid hormone (untreated controls; labeled with a red fluorescent dye) and one from cells that were treated with glucocorticoid hormones (glucocorticoid-treated; labeled with green fluorescent dye). You look at a spot on the chip representing the gene for glutamyltransferase and it is green. How do you interpret this result?
a) The glutamyltransferase gene is expressed in the control cDNA population, but not in the glucocorticoid-treated population. b) The glutamyltransferase gene is expressed essentially equally in both cDNA populations. c) The glutamyltransferase gene is not expressed in the control cDNA population, but it is expressed in the glucocorticoid-treated population. d) The glutamyltransferase gene is not affected by glucocorticoid treatment.
