When the sun reaches the end of  released into space, forming a life cycle, the expanded part will be Planetary nebula.

Explanation:

Planetary nebula formed after when the external layer is shredded due to running out of fuel so that it can burn. This external layer of gas expand into the space, the shape of nebula can often be ring shaped or even a bubble. At the centre of this nebula it has the shinning left over middle part of the star. This star can also be seen. The temperature of the nebula is 100000C. The planetary nebula last for about 10000 years between its formation and the recombination.

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.
