Explanation:
Both Darwin and Mendel proposed their theory at the same time but they never communicated with each other. They both explained the population and studied the variation between them and in them.
The variation within a population could be of two types: the discontinuous traits and the quantitative trait.
A discrete trait refers to a trait that is usually controlled by only one gene that is only two alleles or two variants are observed in the population whereas the quantitative trait is a trait that can be determined by more than one gene like the variation in height.

Answer:
The type of pollution demonstrated is sediment pollution.
Explanation:
- Sediment pollution is the deposition of waste products in rivers, lakes and streams by the means of soil erosion. 
- So in the abandoned construction site, sediment pollution is the major issue that causes the environment's wind and water to pollute heavily.
- The waste is swept and carried to different places that pollutes the environment badly due to the exposed construction site.
