Answer the following question given this paragraph: A population can't keep growing bigger and bigger forever. Sooner or later, it will run out of things it needs. For a given species, there is a maximum population that can be supported by the environment. This maximum is called the carrying capacity . When a population gets close to the carrying capacity, it usually grows more slowly ( Figure below ). When the population reaches the carrying capacity, it stops growing. Q: For any given species, what term means the maximum population that can be supported by the environment? Choices: - zero population growth - mass extinction - tipping point - carrying capacity A:
carrying capacity
Answer the following question given this paragraph: Q: In the case of the thyroid hormone pathway, thyroid hormone itself carries out what kind of feedback? Choices: - positive - continued - effective - negative A:

Q: Answer the following question given this paragraph: Processes in which matter changes between liquid and solid states are freezing and melting. Q: Processes in which matter changes between liquid and solid states are freezing and? Choices: - boiling - steaming - transpiration - melting A:
A: melting
Question: Answer the following question given this paragraph: A refrigerator must do work to reverse the normal direction of thermal energy flow. Work involves the use of force to move something, and doing work takes energy. In a refrigerator, the energy is usually provided by electricity. You can read in detail in the Figure below how a refrigerator does its work. For an animation of how a refrigerator works, go to this URL: http://www. chemistry. wustl. edu/~edudev/LabTutorials/CourseTutorials/LabTutorials/Thermochem/fridge_movie. html. Q: A refrigerator must do work to reverse the normal direction of what? Choices: - visible energy flow - coolant energy flow - spectral energy flow - thermal energy flow A:
Answer: thermal energy flow

Answer the following question given this paragraph: The fruiting bodies are usually produced at the surface of the food source, rather than hidden within it. This allows the reproductive spores to be easily shed and carried away by the wind, water, or animals. The fruiting bodies are usually the only indication that a fungus is present. Like icebergs, the fruiting bodies represent only a tiny fraction of the whole fungus, with most of the fungus hidden from view. Q: Where is the fruiting body normally produced in relation to the food source? Choices: - at the root - in the soil - underneath the surface - at the surface A:
**Answer**
at the surface

Answer the following question given this paragraph: The magnetic field has north and south poles. The magnetic poles do not exactly match the geographic poles. So the North Magnetic Pole is not the same as the geographic North Pole. The same is true of the South Pole. The magnetic field is created by the movement of molten metal in the outer core. Q: The movement of molten metal in earth's outer core creates? Choices: - the gravitational field - the stellar field - earthquakes - the magnetic field A:
(Answer)
the magnetic field
