Answer the following question given this paragraph: Because the Sun is not solid, it does not have a defined outer boundary. It does, however, have a definite internal structure with identifiable layers ( Figure below ). Since the layers are not solid, the boundaries are fuzzy and indistinct. From inward to outward, the layers are: the core, the radiative zone, and the convection zone. Q: What is the innermost layer of the sun called? Choices: - Convection Zone - Chromosphere - Photosphere - the core A:
(Answer)
the core
Ques: Answer the following question given this paragraph: Under the right conditions, light can be used to eject electrons from a solid material. Q: Light can be used to eject what from a solid material? Choices: - protons - calories - neutrons - electrons A:
Ans: electrons
(Q).
Answer the following question given this paragraph: When light is refracted its wavelength and speed change; however, its frequency remains the same as the frequency of the light source. Proof of this is that light retains its original color under water. For example, blue light is still blue under water. Q: Light retains its original color under water because what remains the same when light is refracted? Choices: - wave length - density - sound - frequency A:
(A).
frequency
Ques:Answer the following question given this paragraph: An acid-base indicator is a substance that displays different colors when in the presence of an acid or a base. How does that work? An indicator is a weak acid that ionizes within a known pH range, usually about 2 pH units. We can represent the protonated form of the indicator molecule as HIn and the deprotonated form as In . The following equilibrium exists for the indicator. Q: A substance that displays different colors when in the presence of an acid or a base is called what? Choices: - pH scale - reactor - litmus test - an acid-base indicator A:

Ans:an acid-base indicator
Answer the following question given this paragraph: Q: Metabolism is an emergent property of life that arises from orderly interactions between what? Choices: - tissues - body systems - nutrients - molecules A:
molecules
