Rank these events in the order that they occur during the repair of double-strand breaks by recombination:
A. After invasion of the homologous chromosome the 3’ end of the invading strand acts as a primer for DNA synthesis.
B. The broken ends are processed, with the 5’-ending strand selectively degraded to create 3’ overhangs.
C. The 3’ single strand extensions invade the homologous chromosome, displacing the homologous strand and base pairing with the complementary strand.
D. As a result of the two strand invasions, the two homologues are linked at two places and are called a branched intermediate.

the awnser is d i think

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.
