The frequency of two alleles in a gene pool is 0.19 (A) and 0.81(a). Assume that the population is in Hardy-Weinberg equilibrium. (a) Calculate the percentage of heterozygous individuals in the population. According to the Hardy-Weinberg Equilibrium equation, heterozygotes are represented by the 2pq term.For each ion, the equilibrium (or reversal) potential is the membrane potential where the net flow through any open channels is 0.In other words, at E rev, the chemical and electrical forces are in balance.E rev can be calculated using the Nernst equation.In mammalian neurons, the equilibrium potential for Na + is ~+60 mV and for K + is ~-88 mV.If initially 0.20 M solution of HCN is present, calculate the equilibrium concentration of {eq}CN^- {/eq} The equilibrium constant {eq}K_c {/eq} for the reaction {eq}2ICl (g) \rightleftharpoons I_2...rokoko clothingautoworld metrotownsheds for sale in rhode island1984 yamaha tt600radon boat L4a
