Jim thinks that the more air pressure in a ball, the higher it will bounce. He collects some balls and an air pump with a pressure gauge. How should Jim
test this?
1 point
a. Bounce balls with different amounts of force from the same height
D b. Bounce balls having different air pressures from the same height
c Bounce balls having the same air pressure at different angles from the floor.
d Bounce balls having the same amount of air pressure from different heights

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.

all these collisions do one thing, and that thing is explained in the last option. when dusst, rocks and ice collide, they harden and form giant layers of rocks or hard ice.

d)   to harden materials to form different parts of earth’s layers
