1. I   2. F   3. E   4. B   5. D   6. H  7. G  8. C  9. A

Explanation:

(A) Insulin is a signal protein involved in controlling blood glucose levels.

(B) Carboxylase is an enzyme required in the process of carboxylation.

(C) Rhodopsin is a light sensitive receptor found in the retina of the eye.

(D) Haemoglobin transports oxygen in blood.

(E) Ferritin is a protein that stores iron.

(F) Myosin is a motor protein that carries out its function with actin

(G) Green fluorescent protein has the special purpose of tagging proteins.

(H) Tubulin is a structural protein that gives rise to microtubules that support living cells.

(I) Homeodomain proteins are involved in the regulation of gene expression.

structure is maintained and sustained by:

-cytoskeleton: gives cells coherence

-cell wall: support

-cytoplasm: shape

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.
