Hamptonium is a radioactive substance that decays into two parts Monctonium and one part St. Johnite (i.e. 3 units of Hamptonium decays into 2 units of Monctonium and 1 unit of St. Johnite) . Hamptonium has a half-life of 1 million years. We find a rock that contains 20 units […]

1. The final steps in fermentation appear to be unnecessary: the generation of lactate or ethanol does not produce any additional energy for the cell. Explain why cells growing in the absence of oxygen could not simply discard pyruvate a waste product. 2. What, if anything, is wrong with the […]

Question 1: A large population consists of genotypesAA,Aa, and aa frequencies of 0.1,0.6. and 0.3, respectively. a.) What are the allele frequencies in this population? b.) calculate the expected allele and genotype frequecies ofzygotes after one generation of random mating Question 2: Critize the following statements for random matingpopulations: a.) […]

Suppose that the extracellular concentration of Cl– is 123 mM and the intracellular concentrationis 4 mM. The membrane electrical potential (?V) is 0.06 V, inside negative relative to outside. At 298 K, for transport of Cl– ions from the outside into the cell: 1) Calculate the electrical potential term of […]
