"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.

Answer:
The answer to your question is 0.33 moles of H₃PO₄
Explanation:
Data
moles of Ca(OH)₂ = 0.050
moles of H₃PO₄ = ?
Process
1.- Write the balanced chemical equation
3Ca(OH)₂ + 2H₃PO₄ ⇒ Ca₃(PO₄)₂ + 6H₂O
Reactants Elements Products
3 Ca 3
12 H 12
14 O 14
2.- Calculate the moles of phosphoric acid
3 moles of calcium hydroxide --------------- 2 moles of phosphoric acid
0.5 moles of calcium hydroxide ----------- x
x = (0.5 x 2)/3
x = 0.33 moles
