Answer the following question given this paragraph: The biogeochemical cycle that recycles water is the water cycle. The water cycle involves a series of interconnected pathways involving both the biotic and abiotic components of the biosphere. Water is obviously an extremely important aspect of every ecosystem. Life cannot exist without water. Many organisms contain a large amount of water in their bodies, and many live in water, so the water cycle is essential to life on Earth. Water continuously moves between living organisms, such as plants, and non-living things, such as clouds, rivers, and oceans ( Figure below ). Q: What is the biogeochemical cycle that recycles water called? A:
OPTIONS:
- water theory
- Liquid Cycle
- Water Table
- water cycle

Answer: water cycle

Question: Answer the following question given this paragraph: Heat below Earth's surfacecalled geothermal energy can be used to produce electricity. A power plant pumps water underground where it is heated. Then it pumps the water back to the plant and uses its thermal energy to generate electricity. On a small scale, geothermal energy can be used to heat homes. Installing a geothermal system can be very costly, however, because of the need to drill through underground rocks. Q: What do you call the heat below earth's surface that can be used to produce electricity? A:
OPTIONS:
- inert energy
- renewable energy
- natural energy
- geothermal energy
Answer: geothermal energy

input with options: Answer the following question given this paragraph: Q: Many parasites have complex life cycles involving multiple ? A:
OPTIONS:
- features
- viruses
- diseases
- hosts
output: hosts

Q: Answer the following question given this paragraph: Sometimes large numbers of species go extinct in a short amount of time. This is a mass extinction . The causes of different mass extinctions are different: collisions with comets or asteroids, massive volcanic eruptions, or rapidly changing climate are all possible causes of some of these disasters ( Figure below ). Q: What term is used to describe large numbers of species that go extinct in a short amount of time? A:

OPTIONS:
- formation extinction
- organic extinction
- species extinction
- mass extinction

A: mass extinction

Answer the following question given this paragraph: Innate behaviors occur in all animals. However, they are less common in species with higher levels of intelligence. Humans are the most intelligent species, and they have very few innate behaviors. The only innate behaviors in humans are reflexes. A reflex is a response that always occurs when a certain stimulus is present. For example, a human infant will grasp an object, such as a finger, that is placed in its palm. The infant has no control over this reaction because it is innate. Other than reflexes such as this, human behaviors are learnedor at least influenced by experiencerather than being innate. Q: Innate behaviors occur in all animals. however, they are less common in species with higher levels of what? A:
OPTIONS:
- hormones
- interdependence
- nonverbal communication
- intelligence
intelligence
