Answer the following question given this paragraph: If a solute is a gas, increasing the temperature decreases its solubility. For example, less carbon dioxide can dissolve in warm water than in cold water. Q: In which kind of water can less carbon dioxide dissolve? Choices: - cool water - tap water - salt water - warm water A:
warm water
Answer the following question given this paragraph: At each level of a food chain, a lot of energy is lost. Only about ten percent of the energy passes to the next level. Where does that energy go? Some energy is given off as heat. Some energy goes into animal wastes. Energy also goes into growing things that another consumer can't eat, like fur. It's because so much energy is lost that most food chains have just a few levels. There's not enough energy left for higher levels. Q: Loss of energy is the reason that what typically has few levels? Choices: - humans - the atmosphere - video games - food chain A:
food chain

Question: Answer the following question given this paragraph: Some processes in the body are regulated by positive feedback. Positive feedback is when a response to an event increases the likelihood of the event to continue. An example of positive feedback is milk production in nursing mothers. As the baby drinks her mother's milk, the hormone prolactin, a chemical signal, is released. The more the baby suckles, the more prolactin is released, which causes more milk to be produced. Other examples of positive feedback include contractions during childbirth. When constrictions in the uterus push a baby into the birth canal, additional contractions occur. Q: Where does a baby travel to after leaving the uterus? Choices: - tissue canal - ear canal - nasal canal - birth canal A:
Answer: birth canal

Answer the following question given this paragraph: Eukaryotes evolved about 2 billion years ago. Unlike prokaryotes, eukaryotes have a cell nucleus. They have more structures and are better organized. Organelles within a eukaryote can perform certain functions. Some supply energy; some break down wastes. Eukaryotes were better able to live and so became the dominant life form. You can see an example of a eukaryotic cell below ( Figure below ). Q: Unlike prokaryotes, eukaryotes have a what? Choices: - flagellum - cell wall - mitochondria - cell nucleus A:
**Answer**
cell nucleus
