current systems that are used to examine below the earths crust on dry land do not work well underwater. however an innovative marine seismic system samples data in all directions, allowing it to capture returning wave fields in 3-D. the engineering of such a system to create enhanced images of structures beneath the sea floor are beneficial for all of the reasons except

true, i don't really know what you're asking but from the info you provided im guessing the answer is true.

the answer 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.
