Calculate the amount of reagent and water required to make the following solutions. Do not assume you have a stock solution unless instructed to do so.
a) 1.00 L of 20.00mM Tris-HCl, 50.0mM NaCl, 20.00mM MgSO4 x 7H2O, 5.00mM CaCl2
b) 275 mL of 25% Na2HCO3, 18.0% EtOH
c) 750.0mL of 0.2M sodium citrate, 10.00mM SDS (from 0.50M stock), 2.5% glycerol
d) Calculate molarity of 15% NaCl and 27% hydrochloric acid

Based on what you know about anole morphology and the process of adaptation via natural selection, do you think it is possible for a generalist anole to be as adept as each of the specialist anole ecomorphs at living (for example: climbing, running, hunting, etc.) in the different island habitats? In other words, do you think it is possible for a single anole species to be as good at living on twigs as the twig ecomorph anoles, and as good at living on trunks as the trunk ecomorph anoles, and as good at living on the tops of trees as the trunk-crown ecomorph anoles, etc.?
