Answer:
Surfactants <u>reduces</u><u> surface tension of water </u>and <u>promotes</u><u> emulsification</u>.
Explanation:
Surfactant is generally an organic molecule or compound that is amphiphilic in nature. Surfactants can act perform as emulsifiers, detergents, foaming agents, dispersants and wetting agents.
Surfactants decreases the surface tension between the solid and liquid, gas and liquid and two liquids and can acts as emulsifying agents, cleaning agents, dispersing agents, foaming and anti-foaming agents.

Answer: A. the gravitational pull of the Sun
The sun is providing a centripetal force pulling the earth inward toward the sun. At the same time, the inertia of the earth is making it want to move forward in a straight line. The two forces work together to create the net effect of the earth orbiting around the sun. Other planets, moons, asteroids, and celestial objects exert gravitational forces on the earth as well, but nowhere near the amount of what the sun does.
