Answer the following question given this paragraph: The ideal gas law is used like any other gas law, with attention paid to the unit and making sure that temperature is expressed in Kelvin. However, the ideal gas law does not require a change in the conditions of a gas sample. The ideal gas law implies that if you know any three of the physical properties of a gas, you can calculate the fourth property. Q: The ideal gas law is used like any other gas law, with attention paid to the unit and making sure that temperature is expressed in kelvin. however, the ideal gas law does not require a change in the conditions of a gas sample. the ideal gas law implies that if you know any three of the physical properties of a gas, you can calculate this? Choices: - second - third - unrelated - fourth A:
fourth
Answer the following question given this paragraph: An electric transformer is a device that uses electromagnetic induction to change the voltage of electric current. Electromagnetic induction is the process of generating current with a magnetic field. It occurs when a magnetic field and electric conductor, such as a coil of wire, move relative to one another. A transformer may either increase or decrease voltage. You can see the basic components of an electric transformer in the Figure below . For an animation showing how a transformer works, go to this URL: http://www. youtube. com/watch?v=VucsoEhB0NA . Q: What type of device uses electromagnetic induction to change the voltage of electric current? Choices: - radioactive transformer - hot transformer - mechanical transformer - electronic transformer A:
electronic transformer
Q: Answer the following question given this paragraph: Each species has a characteristic number of chromosomes. Chromosomes are coiled structures made of DNA and proteins called histones ( Figure below ). Chromosomes are the form of the genetic material of a cell during cell division. See the "Chromosomes" section for additional information. Q: Each species has a characteristic number of what coiled structures made of dna and proteins? Choices: - genes - ribosomes - prokaryotes - chromosomes A:
A: chromosomes
Question: Answer the following question given this paragraph: Hydrocarbons are extremely important to modern life. Their most important use is as fuels. Hydrocarbons are also used to manufacture many products including plastics. The main source of hydrocarbons is fossil fuels. Q: What is the main source of hydrocarbons? Choices: - photosynthesis - greenhouse gases - decomposers - fossil fuels A:
Answer: fossil fuels

Answer the following question given this paragraph: Specific scents are often associated with our memories of places and events. That's because scents are more novel or specific than shapes or other things you might see. So an odor similar to that of your grandmother's kitchen or pantry might be more quickly associated with your memories of that place than a similar sight, which might be more generalized. Q: Specific scents are often associated with what? Choices: - pheromones - behaviors - instincts - memories A:
**Answer**
memories

Answer the following question given this paragraph: Humans have caused many extinctions by introducing species to new places. For example, many of New Zealand's birds have adapted to nesting on the ground. This was possible because there were no land mammals in New Zealand. Then Europeans arrived and brought cats, foxes, and other predators with them. Several of New Zealand's ground nesting birds, such as this flightless kiwi, are now extinct or threatened because of these predators. Q: What can ultimately result when species are introduced to a new place and prey on other species? Choices: - depletion - over population - elimination - extinction A:
(Answer)
extinction
