Answer:
Poaching.
Explanation:
The descriptions for each of the terms you listed:
- poaching: illegal hunting of wild animals
- habitat destruction: the process in which a habitat becomes unsuitable for supporting life, often by human activity
- pollution: the introduction of hazardous or harmful waste into the environment
- nonnative species: a species introduced to a new habitat, often by human activity, that thrives unusually well due to having no natural predators in its new habitat.
Hunting elephants (an illegal activity in many countries) for their ivory is considered poaching.
Answer:
To separate an insoluble solid from a soluble solid: Mixing the mixture with water, filtering out the insoluble solid, and then evaporating the water to isolate the soluble solid.
Explanation:
D. impermeable rocks
Explanation:
Impermeable rocks is the factor among the give choices that will increase the amount of water runoff on the surface.
Surface run-off is liquid water that flows and moves on the earth surface.
- An impermeable rock is a rock that lacks porosity and permeability.
- Porosity is the amount or percentage of void spaces in rock.
- Permeability is the inter-connectivity of the pores.
- When a rock is impermeable, it will not allow water to infiltrate.

Answer:
0.12 M hydrofluoric acid + 0.17 M potassium fluoride
Explanation:
To make a buffer, you must to have an aqueous mixture of a weak acid and its conjugate base or vice versa.
Knowing that:
0.32 M calcium chloride + 0.27 M sodium chloride: <em>is not a good buffer system </em>because CaCl₂ and NaCl are both salts.
0.35 M ammonia + 0.36 M calcium hydroxide <em>is not a good buffer system </em>because ammonia is a weak base but calcium hydroxide is a strong base
0.19 M barium hydroxide + 0.28 M barium chloride <em>is not a good buffer system </em>because Ba(OH)₂ is a strong base.
0.12 M hydrofluoric acid + 0.17 M potassium fluoride <em>is a good buffer system </em>because HF is a weak acid and KF (F⁻ in aqueous medium), is its conjugate base
0.20 M hydrobromic acid + 0.22 M sodium bromide <em>is not a good buffer system </em>because HBr is a strong acid.
