Answer the following question given this paragraph: Physics is the study of energy and how it interacts with matter. Important concepts in physics include motion, forces such as magnetism and gravity, and different forms of energy. Physics concepts can answer all the questions on the right page of the notebook in Figure above . Q: What is the study of energy and how it interacts with matter? Choices: - quantum mechanics - cosmology - kinetics - physics A:
physics
Answer the following question given this paragraph: The water molecule, like the ammonia and methane molecules, has a tetrahedral domain geometry. In the water molecule, two of the electron pairs are lone pairs rather than bonding pairs. The molecular geometry of the water molecule is referred to as bent . The H-O-H bond angle is 104.5, which is smaller than the bond angle in NH 3 . Q: In the water molecule, two of the electron pairs are lone pairs rather than what? Choices: - bonding ions - acid pairs - ions pairs - bonding pairs A:
bonding pairs
Q: Answer the following question given this paragraph: The small intestine a is narrow tube that starts at the stomach and ends at the large intestine ( Figure above ). In adults, the small intestine is about 23 feet long. Chemical digestion takes place in the first part of the small intestine. Many enzymes and other chemicals are secreted here. The small intestine is also where most nutrients are absorbed into the blood. The later sections of the small intestines are covered with tiny projections called villi ( Figure below ). Villi contain very tiny blood vessels. Nutrients are absorbed into the blood through these tiny vessels. There are millions of villi, so, altogether, there is a very large area for absorption to take place. In fact, villi make the inner surface area of the small intestine 1,000 times larger than it would be without them. The entire inner surface area of the small intestine is about as big as a basketball court!. Q: Where does the small intestine begin? Choices: - mouth - colon - spleen - stomach A:
A: stomach
Question: Answer the following question given this paragraph: Using Lewis Dot Symbols to Describe Covalent Bonding The valence electron configurations of the constituent atoms of a covalent compound are important factors in determining its structure, stoichiometry, and properties. For example, chlorine, with seven valence electrons, is one electron short of an octet. If two chlorine atoms share their unpaired electrons by making a covalent bond and forming Cl2, they can each complete their valence shell:. Q: If two chlorine atoms share their unpaired electrons by making a covalent bond and forming cl2, they can each complete their what? Choices: - hypothesized shell - radiative shell - electron shell - valence shell A:
Answer: valence shell

Answer the following question given this paragraph: The liver is an organ of both digestion and excretion. It produces a fluid called bile , which is secreted into the duodenum. Some bile also goes to the gall bladder , a sac-like organ that stores and concentrates bile and then secretes it into the small intestine. In the duodenum, bile breaks up large globules of lipids into smaller globules that are easier for enzymes to break down. Bile also reduces the acidity of food entering from the highly acidic stomach. This is important because digestive enzymes that work in the duodenum need a neutral environment. The pancreas contributes to the neutral environment by secreting bicarbonate, a basic substance that neutralizes acid. Q: What organ creates bile? Choices: - kidney - pancreas - heart - liver A:
**Answer**
liver
