200J
Explanation:
Given parameters:
Force on boulder = 100N
Distance moved = 2m
Unknown:
Work done = ?
Solution:
Work done on a body is the force applied to move such body in the direction of the force.
Work done = force x distance
Input the parameters in the equation:
Work done = 100 x 2 = 200Nm or 200J
The work done in lifting the boulder is 200J

In populations of all living things, there is a variation of different traits. This is important for the process of evolution and natural selection because if the individuals in the population vary in size, shape, color or any other morphological or physiological trait, the individuals can be more or less successful because of them and therefore natural selection can filter the variations that are the fittest for that environment.
