The cells in this part of a plant form long, vertical tubes. What is the most likely relationship between the structure and function of these specialized
cells?
A. The tubes allow the plant to absorb sunlight for photosynthesis.
B. The tubes prevent potential damage to the leaves caused by
strong winds.
C. The tubes prevent water loss from the leaves.
D. The tubes allow water and nutrients to be transported throughout
the plant

D. The tubes allow water and nutrients to be transported throughout

the plant.

Explanation:

option D supports the description of the cells. The long , vertical tubes transport water and nutrients and are most likely xylem and phloem vessels.

option A is wrong since, chloroplasts inside the cell helps in absorbing sunlight.

option C is also wrong, because water loss is controlled by the stomata in the leaves and they are not long tubes.

option B could possibly be right but option D is better suited.  

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.
