Correct answer
A. Masseter
Explanation
Masseter is the correct answer. Review the question and compare it with the other choices to remember this fact for future exams.
Correct answer
C. Oblate Spheroid
Explanation
Earth is an oblate spheroid. This means it is spherical in shape, but not perfectly round. It has a slightly greater radius at the Equator, the imaginary line running horizontally around the middle of the planet. In addition to bulging in the middle, Earth’s poles are slightly flattened.
Correct answer
B. 576 MP
Explanation
576 MP is the correct answer. Review the question and compare it with the other choices to remember this fact for future exams.
Correct answer
C. It is slightly alkaline
Explanation
pH stands for potential hydrogen. It is used to describe the chemical acidity level vs. alkalinity level of a substance. The pH of Healthy human saliva is slightly alkaline and in the range of 6.2 to 7.6.
Correct answer
C. White
Explanation
Only when mixing frequencies of light, not paint: “White light can be produced by combining only three distinct frequencies of light, provided that they are widely separated on the visible light spectrum. Any three colors (or frequencies) of light that produce white light when combined with the correct intensity are called primary colors of light. There are a variety of sets of primary colors. The most common set of primary colors is red (R), green (G) and blue (B). When red, green and blue light are mixed or added together with the proper intensity, white (W) light is obtained. This is often represented by the equation: R + G + B = W”
Correct answer
B. The sun
Explanation
Comets are small celestial bodies made mostly of ice, dust, and rocky material. They follow elongated orbits around the Sun. When a comet approaches the Sun, its icy surface begins to vaporize, forming a glowing coma (a cloud of gas and dust) around the nucleus, and sometimes developing a visible tail that points away from the Sun due to solar wind. These orbits can vary widely in shape, some being highly elliptical, which means they can take comets very close to the Sun at their perihelion (closest approach) and far away into the outer reaches of the solar system at their aphelion (farthest point). However, regardless of their shape, all comet orbits are ultimately controlled by the gravitational pull of the Sun.
Correct answer
C. Gravitational force
Explanation
Gravitational force is the correct answer. Review the question and compare it with the other choices to remember this fact for future exams.
Correct answer
D. Ionosphere
Explanation
Ionosphere is the correct answer. Review the question and compare it with the other choices to remember this fact for future exams.
Correct answer
C. Cooling process
Explanation
Evaporation is a cooling process because the molecules with higher kinetic energy escape from the liquid surface, taking heat energy with them. As a result, the average kinetic energy of the remaining liquid decreases, causing it to cool down.
