Answer the following question given this paragraph: Only the top 200 meters or so of water receive enough sunlight for photosynthesis. This part of the water is called the photic zone. Below 200 meters, there is too little sunlight for photosynthesis to take place. This part of the water is called the aphotic zone. In this zone, food must come from other sources. It may be made by chemosynthesis, in which microorganisms use energy in chemicals instead of sunlight to make food. Or, food may drift down from the water above. Q: What is the top part of water able to receive enough sunlight for photosynthesis called? Choices: - thymic zone - synthesis zone - fantasmic zone - photic zone A:
photic zone

Answer the following question given this paragraph: AcidBase Titrations Because most common acids and bases are not intensely colored, a small amount of an acid base indicator is usually added to detect the equivalence point in an acidbase titration. The point in the titration at which an indicator changes color is called theendpoint. The procedure is illustrated in Example 21. Q: The point in the titration at which an indicator changes color is called what? Choices: - zeta point - tipping point - chromatic point - end point A:
(Answer)
end point
Ques: Answer the following question given this paragraph: The scientist must next form a conclusion. The scientist must study all of the data. What statement best explains the data? Did the experiment prove the hypothesis? Sometimes an experiment shows that a hypothesis is correct. Other times the data disproves the hypothesis. Sometimes it's not possible to tell. If there is no conclusion, the scientist may test the hypothesis again. This time he will use some different experiments. No matter what the experiment shows the scientist has learned something. Even a disproved hypothesis can lead to new questions. Q: If no conclusion is reached after an experiment, the scientist may retest what? Choices: - conclusion - materials - suggestions - hypothesis A:
Ans: hypothesis

Question: Answer the following question given this paragraph: Junctions are areas between cells that either allow or prevent the movement of materials. Junctions are usually composed of numerous proteins, forming a large molecular complex. Gap junctions, desmosomes and tight junctions are three examples of junctions. Q: What are the areas between cells that either allow or prevent the movement of materials called? Choices: - sections - corners - receptors - junctions A:
Answer:
junctions
