Q: Answer the following question given this paragraph: Fish also have a centralized nervous system with a brain. Fish brains are small compared with the brains of other vertebrates, but they are large and complex compared with the brains of invertebrates. Fish also have highly developed sense organs that allow them to see, hear, feel, smell, and taste. Sharks and some other fish can even sense the very low levels of electricity emitted by other animals. This helps them locate prey. Q: Why do sharks sense low levels of electricity? A:

OPTIONS:
- to locate mates
- to sleep
- to reproduce
- to locate prey

A: to locate prey

input: OPTIONS:
- enzyme
- aldehyde
- carbolic acid
- secondary alcohol Now, answer this question: Answer the following question given this paragraph: A secondary alcohol forms a ketone when oxidized. The secondary alcohol cannot be further oxidized to produce a carboxylic acid. Tertiary alcohols cannot be oxidized in this way, because the carbon atom bonded to the OH group is not also bonded to any hydrogens. Q: What forms a ketone when oxidized? A:
A:
output: secondary alcohol

Answer the following question given this paragraph: Q: What term is used to describe phages capable of using both modes of replicating within a bacterium? A:

OPTIONS:
- moderate phages
- bacteriophage
- lambda phage
- temperate phages

Answer: temperate phages

Problem: OPTIONS:
- digestive system incompatibility
- brain organ incompatibility
- cancer organ incompatibility
- reproductive organ incompatibility
Q: Answer the following question given this paragraph: Figure 18.19 The shape of the male reproductive organ varies among male damselfly species, and is only compatible with the female of that species. Reproductive organ incompatibility keeps the species reproductively isolated. Q: What keeps various species from mating and reproducing outside their own species? A:
Answer: reproductive organ incompatibility

Problem:OPTIONS:
- seismic load
- convection
- evaporation
- radiation

Answer the following question given this paragraph: One reason radiation is dangerous is that it can't be detected with the senses. You normally can't see it, smell it, hear it, or feel it. Fortunately, there are devices such as Geiger counters that can detect radiation. A Geiger counter, like the one in Figure below , has a tube that contains atoms of a gas. If radiation enters the tube, it turns gas atoms to ions that carry electric current. The current causes the Geiger counter to click. The faster the clicks occur, the higher the level of radiation. You can see a video about the Geiger counter and how it was invented at the URL below. Q: Geiger counters can be used to detect what, in general? A:
****
A: radiation

Problem:OPTIONS:
- duration
- density
- power
- speed

Answer the following question given this paragraph: Chemical reactions vary widely in the speeds with which they occur. Some reactions occur very quickly. If a lighted match is brought in contact with lighter fluid or another flammable liquid, it erupts into flame instantly and burns fast. Other reactions occur very slowly. A container of milk in the refrigerator will be good to drink for weeks before it begins to turn sour. Millions of years were required for dead plants under Earth's surface to accumulate and eventually turn into fossil fuels such as coal and oil. Q: Exemplified by a lit match bursting into flame or the process that forms fossil fuels, chemical reactions vary greatly in terms of what? A:
****
A:
speed
