Based on what you know about the genetic code, list one or two codons that would most likely code for the same amino acid. This is a hypothetical question; don't look at the table showing the genetic code
What will be an ideal response?
The correct answer(s) would be codons that have identical first two bases, and variation only in the third base (such as CCC and CCA).

You are planning a careful study of the metabolic rate of a spotted bat (Euderma maculatum). At the last minute, you learn that you will not be able to measure caloric intake directly. Should you abandon your study?
A. Yes, because caloric measurement would provide the only meaningful data. B. No, because water intake can provide an indirect measurement of metabolic rate. C. No, because oxygen intake can be measured instead, and it will provide an indirect measurement of metabolic rate. D. No, because carbon dioxide intake can be measured instead, and it will provide an indirect measurement of metabolic rate. E. No, because digestive enzyme production can be measured instead, and it will provide an indirect measurement of metabolic rate.
The idea that femaleness is simply what happens when an embryo does not develop as a male is no longer supported by evidence because of the discovery of
A) the SRY gene in females. B) genes whose expression is necessary for female structures to develop. C) gene that suppress all of the genes on a female's Y chromosome. D) hormones that suppress expression of SRY genes in females.
