Answer:
Work
Explanation:
Work can be referred to as the application of a force (F) over a distance (d). In other words, WORK is done when an applied force causes a body to move. Hence, work is a product of the force and the displacement in the direction of the force i.e. W = F × d
In this case, a desk is PULLED along the floor in your classroom, this best indicates WORK because a force (pull) is applied on the desk causing it to move over a distance in the direction of the pull.

The human eye is a complex adaptation, which has evolved over many millions of years, and similarly to other composite adaptations, it still exhibits the signs of the evolutionary history. The complex adaptation of the human eye is the outcome of the evolution of the past organisms, which have utilized transitional forms of the eye. The evolution of the eye is a cumulative procedure. The evolution of the eye did not take place by random chance, however, it occurs due to billions of years of natural selection.
Cells build carbohydrate polymers by using energy to form glycosidic linkages, the bonds betweenmonosaccharides. A dehydration synthesis reaction forms a bondbetween carbon atoms in twomonosaccharides, sandwiching an oxygen atom between them and releasing a water molecule.
