Answer the following question given this paragraph: The last step in a scientific investigation is communicating what you have learned with others. This is a very important step because it allows others to test your hypothesis. If other researchers get the same results as yours, they add support to the hypothesis. However, if they get different results, they may disprove the hypothesis. When scientists share their results, they should describe their methods and point out any possible problems with the investigation. Results can be communicated in various ways. A scientist usually contributes material through publication in a peer-reviewed scientific journal. Peer-review ensures the material is of an acceptable quality for the scientific community. Scientists also write review articles, book chapters, and even whole books. They also regularly participate in scientific meetings, presenting their material in front of large audiences of their peers. Q: What is the last step in a scientific investigation? A:

OPTIONS:
- documenting findings
- verifying findings
- retesting findings
- communicating findings

Answer: communicating findings

Problem: OPTIONS:
- endocrine
- pulmonary
- nervous
- circulatory
Q: Answer the following question given this paragraph: Mollusks have a circulatory system with one or two hearts that pump blood. The heart is a muscular organ that pumps blood through the circulatory system when its muscles contract. The circulatory system may be open or closed, depending on the species. Q: The heart is a muscular organ that pumps blood through which system? A:
Answer: circulatory

Problem:OPTIONS:
- amplification
- crystalline
- increasefixation
- sublimation

Answer the following question given this paragraph: Snow and ice may also undergo sublimation under certain conditions. This is most likely to happen where there is intense sunlight, very cold temperatures, and dry winds. These conditions are often found on mountain peaks. As snow sublimates, it gradually shrinks without any runoff of liquid water. At the URL below, you can watch a time-lapse video showing sublimation of snow on the highest mountain in the Andes. Q: Snow and ice may also undergo which process where there is intense sunlight, very cold temperatures, and dry winds? A:
****
A: sublimation

Answer the following question given this paragraph: Animal behavior is any way that an animal interact with other animals or the environment. An animal may carry out behaviors alone or with other animals. The photos in Figure below show just a few of the ways that animals behave. Look at the pictures and read about the behaviors they represent. Why do you think the animals are behaving in these ways? And how do the behaviors come about? Which, if any of them, have to be learned?. Q: What is the term for any way that an animal interacts with other animals or the environment? A:
OPTIONS:
- animal biology
- animal way
- immunity
- animal behavior
animal behavior

Answer the following question given this paragraph: In the gasoline industry, what is called isooctane is actually 2,2,4-trimethylpentane. Draw the structure of isooctane. Q: What do they call 2,2,4-trimethylpentane in the gasoline industry? A:
OPTIONS:
- spirogyra
- methane
- xerophyte
- isooctane

Answer: isooctane

input with options: Answer the following question given this paragraph: rem = rad factor where factor is a number greater than or equal to 1 that takes into account the type of radioactive emission and sometimes the type of tissue being exposed. For beta particles, the factor equals 1. For alpha particles striking most tissues, the factor is 10, but for eye tissue the factor is 30. Most radioactive emissions that people are exposed to are on the order of a few dozen millirems (mrem) or less; a medical X-ray is about 20 mrem. A sievert (Sv) is a related unit and is defined as 100 rem. What is a person's annual exposure to radioactivity and radiation? Table 15.3 "Average Annual Radiation Exposure (Approximate)" lists the sources and annual amounts of radiation exposure. It may surprise you to learn that fully 82% of the radioactivity and radiation exposure we receive is from natural sources sources we cannot avoid. Fully 10% of the exposure comes from our own bodieslargely from carbon-14 and potassium-40. Table 15.3 Average Annual Radiation Exposure (Approximate). Q: Most radioactive emissions that people are exposed to are on the order of a few dozen what? A:
OPTIONS:
- ticks
- micrograms
- millivolts
- millirems
output:
millirems
