On an island, finches that fed on large, hard seeds had large beaks. finches with small beaks fed on small, soft seeds. a drought changed the vegetation on the island. after this period, the number of seeds declined. the decrease in small, soft seeds was greater than the decrease in large, hard seeds. what are two ways the decrease in seed availability will affect the population of birds on the island? a. the population of birds with large beaks will increase on the island. b. the population of birds with small beaks will increase on the island. c. the trait for large beaks will be passed on to future generations through natural selection. d. the trait for small beaks will be passed on to future generations through natural selection. e. the population of birds with large beaks and birds with small beaks will be equal on the island.

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.

liquid crystals are matters in a state which have properties between those of conventional liquids and those of solid crystals[1]. liquid crystal is partially ordered and anisotropic. in terms of molecular order, liquid crystal molecules have one-dimensional or two-dimensional long - range order.
