Which of the following does work?
A. An apple growing on a tree.
B. An apple on a table.
C. An apple being pushed across the floor.

C. An apple being pushed across the floor

Explanation:

Do do work, the direction of the force and the motion of the object has to be the same. For example, holding an apple in the air isn’t doing work because the Apple is motionless but the force is going upward from your hand to hold it up. But if you hold the Apple and push it upward then it does work because it is moving upward and you are also pushing upward. Hope this helps!

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."

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.
