SOME ONE PLEASE HELP
Please answer as best as you can even without the stages :) I would really appreciate it!!

1. In what ways are the mutations described in Steps 5-6 and 7-8 different from those described in Steps 9-10 and 11-12?

2. In Steps 11-12, you saw that cystic fibrosis is caused when specific sections of both copies of chromosome 8 are deleted. On the basis of this information, do you think cystic fibrosis is a dominant or recessive trait?

3. Do all mutations result in negative effects?

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.
