Answer the following question given this paragraph: The part of each nephron called the glomerulus is where blood in the capillaries is filtered. Excess water and wastes are filtered out of the blood. The tubule of the nephron collects these substances. Some of the water is reabsorbed. The remaining fluid is urine. Q: Which part of the nephron collects wastes in the blood? Choices: - filter - vesicle - waste sac - tubule A:
tubule
Answer the following question given this paragraph: Ray-finned fish include the majority of living fish species, including goldfish, tuna, salmon, perch, and cod. They have a bony endoskeleton and a swim bladder. Their thin fins consist of webs of skin over flexible bony rays, or spines. The fins lack muscle, so their movements are controlled by muscles in the body wall. You can compare their ray fins with the fleshy fins of lobe-finned fish in Figure below . Q: What type of fish are the majority of living species? Choices: - cartilaginous fish - freshwater fish - lungfish - ray-finned fish A:
ray-finned fish
Q: Answer the following question given this paragraph: An integrated circuit (microchip) is an electronic component that consists of many other electronic components such as transistors. Integrated circuits are used in virtually all modern electronic devices to carry out specific tasks. Q: What is the term for an electronic component that consists of many other electronic components? Choices: - electrical current - creating circuit - networks - integrated circuit A:
A: integrated circuit
Question: Answer the following question given this paragraph: where the (am) designation refers to an ammonia solution, analogous to (aq) used to indicate aqueous solutions. Without a catalyst, the reaction in Equation 21.20 tends to be rather slow. In many cases, the alkali metal amide salt (MNH2) is not very soluble in liquid ammonia and precipitates, but when dissolved, very concentrated solutions of the alkali metal are produced. One mole of Cs metal, for example, will dissolve in as little as 53 mL (40 g) of liquid ammonia. The pure metal is easily recovered when the ammonia evaporates. Solutions of alkali metals in liquid ammonia are intensely colored and good conductors of electricity due to the presence of solvated electrons (e, NH3), which are not attached to single atoms. A solvated electron is loosely associated with a cavity in the ammonia solvent that is stabilized by hydrogen bonds. Alkali metalliquid ammonia solutions of about 3 M or less are deep blue (Figure 21.11 "Alkali MetalLiquid Ammonia Solutions") and conduct electricity about 10 times better than an aqueous NaCl solution because of the high mobility of the solvated electrons. As the concentration of the metal increases above 3 M, the color changes to metallic bronze or gold, and the conductivity increases to a value comparable with that of the pure liquid metals. Q: In many cases, the alkali metal amide salt (mnh2) is not very soluble in liquid ammonia and does what? Choices: - settles - isolates - evaporates - precipitates A:
Answer: precipitates

Answer the following question given this paragraph: The mouth is the first digestive organ that food enters. The sight, smell, or taste of food stimulates the release of digestive enzymes by salivary glands inside the mouth. The major salivary enzyme is amylase. It begins the chemical digestion of carbohydrates by breaking down starch into sugar. Q: The major salivary enzyme is called? Choices: - synthase - mucosa - sucrase - amylase A:
**Answer**
amylase

Answer the following question given this paragraph: Gyroscopes used in guidance systems to indicate directions in space must have an angular momentum that does not change in direction. Yet they are often subjected to large forces and accelerations. How can the direction of their angular momentum be constant when they are accelerated?. Q: What instruments used in guidance systems to indicate directions in space must have an angular momentum that does not change in direction? Choices: - actuators - elevators - magnets - gyroscopes A:
**Answer**
gyroscopes
