Answer the following question given this paragraph: Estuaries: Where the Ocean Meets Fresh Water Estuaries are biomes that occur where a river, a source of fresh water, meets the ocean. Therefore, both fresh water and salt water are found in the same vicinity; mixing results in a diluted (brackish) salt water. Estuaries form protected areas where many of the offspring of crustaceans, mollusks, and fish begin their lives. Salinity is an important factor that influences the organisms and the adaptations of the organisms found in estuaries. The salinity of estuaries varies and is based on the rate of flow of its freshwater sources. Once or twice a day, high tides bring salt water into the estuary. Low tides occurring at the same frequency reverse the current of salt water (Figure 20.30). Q: What are biomes that occur where a river, a source of fresh water, meets the ocean called? A:
OPTIONS:
- waterways
- sediments
- rapids
- estuaries
estuaries

Answer the following question given this paragraph: The gonads secrete sex hormones. The male gonads are called testes. They secrete the male sex hormone testosterone. The female gonads are called ovaries. They secrete the female sex hormone estrogen. Sex hormones are involved in the changes of puberty. They also control the production of gametes by the gonads. Q: What kind of hormones are secreted by organs classified as gonads? A:
OPTIONS:
- growth hormones
- anterior hormones
- cortisol hormones
- sex hormones

Answer: sex hormones

Question: Answer the following question given this paragraph: 15.6 Entropy and the Second Law of Thermodynamics: Disorder and the Unavailability of Energy Entropy is the loss of energy available to do work. Another form of the second law of thermodynamics states that the total entropy of a system either increases or remains constant; it never decreases. Entropy is zero in a reversible process; it increases in an irreversible process. The ultimate fate of the universe is likely to be thermodynamic equilibrium, where the universal temperature is constant and no energy is available to do work. Entropy is also associated with the tendency toward disorder in a closed system. Q: What is the loss of energy available to do work called? A:
OPTIONS:
- negentropy
- force
- power
- entropy
Answer: entropy

input with options: Answer the following question given this paragraph: The chemical reaction that is the opposite of oxidation is called reduction. Following from the notion that oxidation was originally thought to mean only the addition of oxygen, reduction was thought to be only the removal of oxygen from a substance. Many naturally occurring metal ores are present as oxides. The pure metals can be extracted by reduction. Iron is obtained from iron(III) oxide by reacting with carbon at high temperatures. Q: What chemical reaction is the opposite of oxidation? A:
OPTIONS:
- mutation
- condensation
- evaporation
- reduction
output: reduction

Problem: OPTIONS:
- geothermal cycles
- greenhouse gases
- inorganic cycles
- biogeochemical cycles
Q: Answer the following question given this paragraph: Chemical elements and water are constantly recycled in the ecosystem through biogeochemical cycles. Q: Chemical elements and water are constantly recycled in the ecosystem through what? A:
Answer:
biogeochemical cycles
