Which statement best describes what a thylakoid does during photosynthesis?surrounds the grana and keeps them moistenables the light-dependent reactions to occurcombines carbon dioxide and water to make sugarhelps the light-independent reactions to occur

enables the light-dependent reactions to occur

Explanation:

Photosynthesis is a process peculiar to the cells of certain organisms called AUTOTROPHS. It is the process by which they manufacture their food in form of sugars (glucose). Photosynthesis occurs in an organelle found only in plant or algae cells called CHLOROPLAST.

Chloroplast is a structure or organelle that contains a stack of grana called THYLAKOID. These thylakoid contains the CHLOROPHYLL PIGMENT that allows plants absorb light energy during the light-dependent stage of photosynthesis. Hence, THYLAKOID enables the light-dependent reactions, which involves the synthesis of ATP and NADPH, to occur.

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.
