Charles darwin noticed that finches on different islands of the galapagos islands were similar but that their beaks differed. what explanation for these differences did he propose? a. the beaks of the finches are adapted to the way the bird usually gets food. b. the beaks of the finches are randomly selected by genetic mutation. c. the different beaks would one day evolve into identical beaks. d. beak size is related to the size of the finch.

a. as the temperature increases, the kinetic energy of the gas molecules increases & the molecules move faster & further away from each other.

b. if you decrease the temperature of a fixed amount of gas at constant pressure, the combined gas law reduces to charles's law. in this case, volume will also decrease.

it's diluted or concentrated

in a diluted solution, you can add a lot more solute but in concentrated only a little more can be added
