Answer the following question given this paragraph: 2. Sedimentary rocks form when sediments are compacted and cemented together ( Figure below ). These sediments may be gravel, sand, silt or clay. Sedimentary rocks often have pieces of other rocks in them. Some sedimentary rocks form the solid minerals left behind after a liquid evaporates. Q: What kind of rock forms when material such as gravel, sand, silt or clay is compacted and cemented together? Choices: - ingenious - limestone - craters - sedimentary A:
sedimentary

Ques: Answer the following question given this paragraph: A chemical change occurs whenever matter changes into an entirely different substance with different chemical properties. A chemical change is also called a chemical reaction. Many complex chemical changes occur to produce the explosions of fireworks. An example of a simpler chemical change is the burning of methane. Methane is the main component of natural gas, which is burned in many home furnaces. During burning, methane combines with oxygen in the air to produce entirely different chemical substances, including the gases carbon dioxide and water vapor. You can watch some very colorful chemical changes occurring in the video at this URL:. Q: When matter changes into an entirely different substance with different chemical properties, what has occurred? Choices: - mechanical change - gaseous change - physical change - chemical change A:
Ans: chemical change

Answer the following question given this paragraph: Some of the most interesting evidence for evolution comes from vestigial structures . These are body parts that are no longer used but are still present in modern organisms. Examples in humans include tail bones and the appendix. Q: What is the tail bone an example of? Choices: - invertebrate structure - parasitic structure - primordial structure - vestigial structure A:
(A).
vestigial structure
Ques:Answer the following question given this paragraph: Mole fractions describe the fraction or percentage of a mixture that is made up of a particular substance. Q: What describe the fraction or percentage of a mixture that is made up of a particular substance. Choices: - molecular scale - atomic weight - solute level - mole fractions A:

Ans:mole fractions
Question: Answer the following question given this paragraph: The process of getting oxygen into the body and releasing carbon dioxide is called respiration . Sometimes breathing is called respiration, but there is much more to respiration than just breathing. Breathing is only the movement of oxygen into the body and carbon dioxide out of the body. The process of respiration also includes the exchange of oxygen and carbon dioxide between the blood and the cells of the body. Q: The process of getting oxygen into the body and releasing carbon dioxide is called? Choices: - osmosis - persperation - precipitation - respiration A:
Answer:
respiration
