A mutation that confers phenotypic benefits to individuals or a group of individuals would be considered a beneficial mutation.
<em>Mutation involves a sudden change to the gene coding sequence of the DNA. It can occur as a result of substitution, duplication, deletion, inversion, insertion, etc of purine or pyrimidine bases of the DNA.</em>
<u>These changes can be harmful, beneficial, or neutral to individuals. Those that have neutral effects in individuals are also called silent mutations.</u>
In the case of a duplication causing trichomatic vision in humans, it represents a form of beneficial mutation because it enables humans to be able to distinguish between red, green, and blue colors. The ability to distinguish among these colors improves the quality of life of humans.

The main process of preliminary treatment is the removal of coarse solids and other large materials found in raw wastewater.
Explanation:
The preliminary treatment is used to protect operation of wastewater treatment plants. This is done by removing from wastewater any things that damage pumps, or interfere with subsequent treatment process.
The treatment process include coarse screening, grit removal, and used to remove excess amount of oils and greases.
Wastewater screening is the first operation used at wastewater treatment plants. In this process the object such as rags, paper, plastics and metals are removed to prevent damage and clogging of downstream equipment, piping. The modern treatments use both coarse screens and fine screens.
