Answer the following question given this paragraph: Q: What do some animals use to get a feel for their environment? Choices: - neuroreceptors - nociceptors - fibroblasts - mechanoreceptors A:
mechanoreceptors
Answer the following question given this paragraph: There are two common ways to measure pH. When only an approximate pH value is needed, an inexpensive test involves the use of acid-base indicators , which change color based on the relative acidity of the solution. One type of common indicator is litmus paper. For example, if a piece of litmus paper is dipped into an acidic solution (pH below ~4.5), it will turn red, and dipping it into a basic solution (pH above ~8.5) will turn it blue. Solutions of intermediate pH will result in various shades of purple. Because different indicators change color at different pH values, the use of multiple indicators can generally narrow down the possible pH of a solution to a range of about 0.5-1 pH units. Figure below shows the colors exhibited by various indicators at different pH values. Q: How does litmus paper indicate the ph value of a solution? Choices: - by texture - by shape - by smell - by color A:
by color
Q: Answer the following question given this paragraph: The surface tension of water is illustrated by a number of common occurrences. For example, water spiders are able to walk across bodies of water because of surface tension. Even though the spiders are denser than water, they do not sink, because the small amount of weight pressing down on the surface is not enough to break the strong hydrogen bonds that hold the surface together. Q: The ability of a water spider to walk across a body of water is an example of what? Choices: - high density - low gravity - magnetism - surface tension A:
A: surface tension
Question: Answer the following question given this paragraph: The wind belts have names. The Trade Winds are nearest the Equator. The next belt is the westerlies. Finally are the polar easterlies. The names are the same in both hemispheres. Q: What is the name of the wind belt nearest the equator? Choices: - tropical gusts - cyclones - doldrums - trade winds A:
Answer: trade winds

Answer the following question given this paragraph: Prokaryotes are currently placed in two domains. A domain is the highest taxon in the classification of living things. It's even higher than the kingdom. Q: What is the highest taxon in the classification of living things? Choices: - a phylum - a class - a family - a domain A:
**Answer**
a domain
