The ratio of the number of a specified allele in a population to the total of all alleles at its genetic locus is __________

The wave function for an electron in the 1s state of hydrogen is

A major effect from fertilizer runoff is ____________, a process whereby nutrient runoff causes the excess growth of microorganisms, depleting dissolved oxygen levels and killing ecosystem fauna.

Bioethics spotlight.  When considering what course of actions one might take to help an endangered species, we should be guided by what?

If you study the population genetics of a population of finches and find that they are in Hardy-Weinberg equilibrium, that tells you..

Passing Gas Oceans contain a rich store of CO2, as illustrated in the figures below.     Burning more coal would likely increase the total amount of CO2 taken up by the ocean throughout globe. True or False?

Which of the following is likely a case of natural selection at work on local populations of humans – resulting in adaptation to local conditions?  Choose all that apply.

Is this population at Hardy-Weinberg equilibrium? AA Aa aa 0.49 0.42 0.09 Hint: calculate the allele frequencies: p(A) and q(a) and then remember that under Hardy Weinberg equilibrium p2+ 2pq +q2= 1.  With the allele frequencies calculated you can come up with the expected frequencies for AA, Aa, and aa under Hardy-Weinberg.  If these expected frequencies match the frequencies you actually see above it is in HW equilibrium.

In a study of the effects of mutant forms of p53 (a tumor-suppressor gene), it was found that the presence of a mutated allele (abnormal p53) shut down the normal tumor-suppressing abilities of the wildtype p53 allele – causing abnormal cell-growth as if there were no normal p53 present at all. This mutated form of p53 would be an example of what?  Choose all that apply.

The diagram below represents a model of the Carbon cycle, however some of the various processes and carbon reservoirs boxes have been removed and replaced with descriptions such as “Process 1” or “Carbon Reservoir 1”. The arrows represent the potential routes carbon can flow in this system. True or False: It is possible for an atom of carbon found in Carbon Reservoir 1 to eventually end up in dead organisms, including aquatic animals.
