Question

1. a new kind of seed plant has been found on a remote island. this plant has larger, harder seeds than those found on the galapagos islands. which of the following finch adaptations would be likely to arise on this new island? larger beaks smaller beaks longer legs shorter legs 5. which of the following statements best describes the response of finches to drought on the galapagos islands? during drought, individual finches saw that large, hard seeds were the only available food. to crack these harder seeds, individual finches grew their beaks larger, resulting in an increased average beak depth. during drought, finches struggled to open harder seeds. all the scraping and pecking wore down their beaks, resulting in a reduced average beak depth. during drought, only finches with larger - than - average beaks were able to crack the hard seeds that were available. these finches survived while smaller - beaked finches died, resulting in an increased average beak depth in the population. during drought, finches with smaller beaks (and smaller bodies) had an advantage. with reduced food supplies, larger finches (with larger beaks) were more likely to starve. the result was a decrease in average beak depth.

Explanation:

For question 4, larger beaks would be more suitable to crack the larger, harder seeds. For question 5, during drought, finches with larger - than - average beaks could crack hard seeds and survive, increasing the average beak depth in the population due to natural selection.

Answer:

1. Larger beaks
2. During drought, only finches with larger - than - average beaks were able to crack the hard seeds that were available. These finches survived while smaller - beaked finches died, resulting in an increased average beak depth in the population.
