The rough endoplasmic reticulum. The rough ER is responsible for protein synthesis, so they should be abundant in cells that secrete a lot of digestive proteins.
I'm not sure if there were choices here but I would fill in something like "logically" or "scientifically".

Answer:
the individual is a female.
Explanation:
The only thing that indicates the male, is the presence of the Y chromosome, since it's absent, we are looking at a female karyotype.
Through natural selection it happened over many generations and it was gradual, not a sudden change in the founder species. One bird was randomly born with a fatter beak and so could eat a seed that was harder to crack, this meant he lived longer than the other birds or was fitter, so bred more and so more of the offspring had this slightly larger beak. This continued and the birds moved to the islands with their ideal seed and kept getting fatter beaks etc until they were no longer the same species (this is when they can't breed to produce fertile offspring).
