Which compound contains a triple bond? 2 C's are connected with a single line, and each has an H attached by a single line above, below, and outside.
2 C's are connected with 2 parallel lines. There are H's connected with single lines above left, above right, below right, and below left of the 2 C's.
A C is connected to an O with 2 parallel vertical lines, and below left to H with a single line and below right to O H with a single line.
2 C's are connected by 3 parallel lines. There is an H connected with a single line to the left and to the right.

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.

for a different answer set the answer would be because the oxygen in the water had depleted (apex)
