How did the drought affect the size of the bird beaks? O beak depth decreased
O beak depth increased
O beak depth stayed mostly the same

Because the drought reduced the number of seeds and finches with bigger beaks were able to eat the larger and harder seeds so more of them survived. So, the beak depth increased.

This type of galaxy is an approximately ellipsoidal shape and a smooth, nearly featureless image. they are the largest single star systems, in the universe and are built by the collisions of many smaller galaxies.
