Imagine that these finches did all live on the same island. they were able to co-exist because they survived on different foods. imagine a change in climate, a drought, and certain plants were no longer able to survive on the island. seeds that were a food resource become scarce. you might expect all but one of these things to happen among the finch populations. that is

a) not all of the finches are able to survive.
b) some finches fly to nearby islands to find food.
c) beak shapes changed so finches were able to eat other food resources.
d) finches with beaks adapted for insect catching are

What problem would a person have if the nucleic acid in one of his or her cells were damaged?

Hot air balloons float in the air because of the difference in density between cold and hot air. in this problem, you will estimate the minimum temperature the gas inside the balloon needs to be, for it to take off. to do this, use the following variables and make these assumptions: the combined weight of the pilot basket together with that of the balloon fabric and other equipment is w. the volume of the hot air inside the balloon when it is inflated is v. the absolute temperature of the hot air at the bottom of the balloon is th (where th> tc). the absolute temperature of the cold air outside the balloon is tc and its density is ďc. the balloon is open at the bottom, so that the pressure inside and outside the balloon is the same. as always, treat air as an ideal gas. use g for the magnitude of the acceleration due to gravity.

Predict whether the changes in enthalpy, entropy, and free energy will be positive or negative for the boiling of water, and explain your predictions. how does temperature affect the spontaneity of this process?
