A student notices that when bananas are kept near other fruits, the other fruits ripen faster. She wonders what causes the other fruits to ripen more quickly and thinks that bananas must have an influence on the ripening process. She decides to perform an experiment. She gathers bananas and apples and places an apple by itself at location A and an apple next to a banana at location B. She then waits for five days and records how ripe each apple is.

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.
