A researcher working on an isolated island discovers what she thinks is a new species of bird. It has a longer beak than most birds on the island and different color plumage. Its song is different from the songbirds on the island. Which of the following tests would be most helpful in determining if the bird is a new species or not?
a. Isolate proteins from the bird's eggs, separate them on a western blot, and compare them to proteins isolated from other island bird's eggs.
b. Breed the bird with other island birds.
c. Document all of the physical differences between the new bird and the existing island birds.
d. Sequence the bird's genome.

answer : haversian

[explanation: -(compact bone is organized as parallel columns, known as haversian systems, which run lengthwise down the axis of long bones. these columns are composed of lamellae, concentric rings of bone, surrounding a central channel, or haversian canal, that contains the nerves, blood vessels, and lymphatic system of the bone)]

ask your friends for what they got then copy it down if you don't have any friends which is fine than google it or pay the teacher

idk im sorry.

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.
