Answer the following question given this paragraph: Your large intestine is not just made up of cells. It is also an ecosystem , home to trillions of bacteria known as the "gut flora" ( Figure below ). But don't worry, most of these bacteria are helpful. Friendly bacteria live mostly in the large intestine and part of the small intestine. The acidic environment of the stomach does not allow bacterial growth. Q: Friendly bacteria live mostly in the large intestine and part of the small intestine, because what organ is too acidic? A:
OPTIONS:
- skin
- rectum
- liver
- stomach
stomach

Answer the following question given this paragraph: When the temperature of reactants is higher, the rate of the reaction is faster. At higher temperatures, particles of reactants have more energy, so they move faster. They are more likely to bump into one another and to collide with greater force. For example, when you fry an egg, turning up the heat causes the egg to cook faster. The same principle explains why storing food in a cold refrigerator reduces the rate at which food spoils (see Figure below ). Both food frying and food spoiling are chemical reactions that happen faster at higher temperatures. Q: Which temperatures cause particles of reactants to have more energy? A:
OPTIONS:
- non-existant
- reducing
- lower
- higher

Answer: higher

Question: Answer the following question given this paragraph: Radiation has several important uses, including diagnosing and treating cancer. Q: Diagnosing and treating cancer is a beneficial use of what potentially dangerous energy? A:
OPTIONS:
- thermal
- mechanical
- solar
- radiation
Answer: radiation

input with options: Answer the following question given this paragraph: Seawater has lots of salts in it. This increases its density (mass per volume) over fresh water. Temperature and pressure also affect density. Q: Salt in seawater causes it to have greater what, which is also affected by temperature and pressure? A:
OPTIONS:
- mass
- volume
- area
- density
output: density

Q: Answer the following question given this paragraph: The nucleus divides during mitosis, and the cytoplasm divides during cytokinesis. Q: When does the nucleus divide? A:

OPTIONS:
- meiosis
- photosynthesis
- epistasis
- mitosis

A: mitosis

Answer the following question given this paragraph: The Sun supports most of Earth's ecosystems. Plants create chemical energy from abiotic factors that include solar energy. The food energy created by producers is passed through the food chain. Q: What supports most of earth's ecosystems? A:
OPTIONS:
- oceans
- moon
- crust
- sun
