Which option should a person avoid doing in order to better protect the quality of watersheds?
Norma-Jean [14]

"People should remove native plants around watersheds" option should a person avoid doing in order to better protect the quality of watersheds.

<u>Option: A</u>

<u>Explanation:</u>

Watershed is basically a source of large amount of water like river, sea, etc to another location like lake, ponds and stream.This is seen majorly during rainy season by water harvesting to supply further for farming, portable water plant, manufacturing sectors, enrich habitat to number of plants and animals, etc. Waterways face issues when erosion, pollutants and runoff of animal waste take place, which act as barrier for water flow, as it decreases the quality which affect aquatic animals life, reduce oxygen content. Native plants near watersheds is also a habitat for many animals and species thus it should not be removed until some major flaw occurs.

To prepare a lab solution a chemist dissolves solid potassium chloride in a given
Neporo4naja [7]

The solution could be described like a saturated and concentrated solution.

<h3>Solutions</h3>

Dissolution of solutions can occur in certain ways. These ways depend on the solvent dilution coefficient and the amount of solute.

If the amount of solute is less than the solvent can dissolve, the solution is unsaturated.

If the amount of solute is exactly the same, the solution is saturated.

If the amount is greater, the solution is supersaturated.

So, since the amount of solute is exactly equal to the amount that the solvent can dissolve, the solution is saturated and concentrated.
