Which statement correctly describes the difference between meiosis i and meiosis ii?
meiosis i results in two haploid (n) daughter cells, each with half the number of chromosomes as the original cell. meiosis ii results in four haploid (n) daughter cells.
meiosis i
prophase i- synapsis occurs (each pair of chromatids joins its homologous pair and forms a tetrad) (group of 4 chromatids); recombination occurs ("crossing over", pieces of tetrad twist around and exchange segments
metaphase i- tetrads line up along the equator of the cell
anaphase i- non-disjunction occurs- chromosome pairs separate
telophase i- cells divide and 2 haploid daughter cells are formed
meiosis ii
prophase ii- chromosomes move toward the middle of the cell
metaphase ii- chromosomes line up at the equator
anaphase ii- chromosomes separate into chromatids
telophase ii- both daughter cells divide and 4 haplod cells are formed

An enzymatic hydrolysis of fructose-1-p, fructose-1-p(aq) + h2o(l) - fructose (aq) + pi (aq) was allowed to proceed to equilibrium at 25°c. the original concentration of fructose-1-p was 0.2 m, but when the system had reached equilibrium, the concentration of fructose-1-p was only 6.52 x 10^-5 m. calculate the equilibrium constant for this reaction and the free energy of hydrolysis of fructose-1-p.
