Which one of the equation pairs illustrates a favorable energetic coupling in a cell? (i. e. One reaction releases sufficient energy to drive the other to completion). Select ALL that apply. Equation 1: ATP + H2O → ADP + Pi ΔG1 = –7 kcal/mol Equation 2: phosphoenolpyruvate + H2O → pyruvate + Pi ΔG2 = –14.8 kcal/mol Equation 3: glucose + Pi → glucose-6-phosphate + H2O ΔG3 = +3.3 kcal/mol Equation 4: ADP + Pi → ATP + H2O ΔG3 = +7 kcal/mol

In a cross between individuals of a species of tropical fish, all of the male offspring have long tail fins, and none of the females possess the trait. mating two of the f1 fish fails to produce females with the trait. explain the inheritance pattern of the trait.

One function of the poly-a tail on eukaryotic mrna sequences is to the mrna be transported from the nucleus to the cytoplasm. prokaryotic mrna also has a poly-a tail. choose the best explanation of the prokaryotic poly-a tail. a. prokaryotic poly-a tails are composed of a different molecular structure compared with eukaryotic poly-a tails. b. prokaryotic poly-a tails have the same functions as eukaryotic poly-a tails, because this process is highly conserved throughout different species. c. prokaryotic poly-a tails aren't important, because prokaryotes don't have nuclei. d. prokaryotic poly-a tails have other functions,because prokaryotes don't have nuclei.
