Answer the following question given this paragraph: acid will form a homogeneous solution with water. (In fact, the solubility of both butanol and pentanoic acid in water is quite low, only about 3 g per 100 g water at 25C. ) 10. An electrolyte is any compound that can form ions when it dissolves in water. When a strong electrolyte dissolves in water, it dissociates completely to give the constituent ions. In contrast, when a weak electrolyte dissolves in water, it produces relatively few ions in solution. Q: What is a compound that can form ions when it dissolves in water called? Choices: - sulfate - compound - isolate - electrolyte A:
electrolyte
Answer the following question given this paragraph: Living things that cause human diseases include bacteria, fungi, and protozoa. Most infectious diseases caused by these organisms can be cured with medicines. For example, medicines called antibiotics can cure most diseases caused by bacteria. Bacteria are one-celled organisms without a nucleus. Although most bacteria are harmless, some cause diseases. Q: Most diseases caused by bacteria can be cured by which medicines? Choices: - hydroxides - antioxidants - inhibitors - antibiotics A:
antibiotics
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: Cell transport refers to the movement of substances across the cell membrane. Probably the most important feature of a cell's phospholipid membranes is that they are selectively permeable. A membrane that is selectively permeable , or semipermeable, has control over what molecules or ions can enter or leave the cell, as shown in Figure below . This feature allows a cell to control the transport of materials, as dictated by the cell's function. The permeability of a membrane is dependent on the organization and characteristics of the membrane lipids and proteins. In this way, cell membranes help maintain a state of homeostasis within cells (and tissues, organs, and organ systems) so that an organism can stay alive and healthy. Q: Cell transport refers to the movement of substances across what structure? Choices: - cell wall - chloroplasm - phloem - cell membrane A:
Answer: cell membrane
*Question*
Answer the following question given this paragraph: Group 14 is called the carbon group. This group contains two metalloids: silicon and germanium. Carbon is a nonmetal, and the remaining elements in this group are metals. Q: What is the name of the two metalloids in the carbon group called? Choices: - titantium and copper - silicon and gold - silver and gold - silicon and germanium A:
**Answer**
silicon and germanium
Q: Answer the following question given this paragraph: In stage two, the pyruvate molecules are transported into the mitochondria. The mitochondria are the organelles known as the energy "powerhouses" of the cells ( Figure below ). In the mitochondria, the pyruvate, which have been converted into a 2-carbon molecule, enter the Krebs cycle. Notice that mitochondria have an inner membrane with many folds, called cristae . These cristae greatly increase the membrane surface area where many of the cellular respiration reactions take place. Q: What organelles are known as the energy "powerhouses" of the cells? Choices: - proteins - atoms - carbohydrates - mitochondria A:
A: mitochondria
