At ASU graduation during the festivities, your great aunt brings a potato salad to share.  Your auntie put the potato salad on a picnic table in the hot sun at 4:00 pm. With your special training in bacterial population ecology, you estimate the population size of bacteria in this dish to be 1500 cells (E. Coli) at 4:30 pm and 3000 cells at 5:30 pm.  Able to replicate in one hour,  how many bacteria will be there by 7:30 pm?  (two growth cycles after the 5:30 pm count). Select only ONE answer choice.  Hint: because this is a population that has just started growing (without an immediate carrying capacity) you should use exponential growth model.

If f(x)=xcosh(x)+2sinh(x), then f'(x)=

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.
