Question: Answer the following question given this paragraph: The classroom in Figure above has artificial light sources in addition to natural sunlight. There are fluorescent lights on the ceiling of the room. There are also projectors on the ceiling that are shining light on screens. In these and most other artificial light sources, electricity provides the energy and some type of light bulb converts the electrical energy to visible light. How a light bulb produces visible light varies by type of bulb, as you can see in Table below . Incandescent light bulbs, which produce light by incandescence, give off a lot of heat as well as light, so they waste energy. Other light bulbs produce light by luminescence, so they produce little if any heat. These light bulbs use energy more efficiently. Which types of light bulbs do you use?. Q: Aside from light, incandescent light bulbs also give off what that wastes energy? A:
OPTIONS:
- temperature
- humidity
- electricity
- heat
Answer: heat

input with options: Answer the following question given this paragraph: Hepatic Portal System The liver is a complex biochemical processing plant. It packages nutrients absorbed by the digestive system; produces plasma proteins, clotting factors, and bile; and disposes of worn-out cell components and waste products. Instead of entering the circulation directly, absorbed nutrients and certain wastes (for example, materials produced by the spleen) travel to the liver for processing. They do so via the hepatic portal system (Figure 20.43). Portal systems begin and end in capillaries. In this case, the initial capillaries from the stomach, small intestine, large intestine, and spleen lead to the hepatic portal vein and end in specialized capillaries within the liver, the hepatic sinusoids. You saw the only other portal system with the hypothalamic-hypophyseal portal vessel in the endocrine chapter. The hepatic portal system consists of the hepatic portal vein and the veins that drain into it. The hepatic portal vein itself is relatively short, beginning at the level of L2 with the confluence of the superior mesenteric and splenic veins. It also receives branches from the inferior mesenteric vein, plus the splenic veins and all their tributaries. The superior mesenteric vein receives blood from the small intestine, two-thirds of the large intestine, and the stomach. The inferior mesenteric vein drains the distal third of the large intestine, including the descending colon, the sigmoid colon, and the rectum. The splenic vein is formed from branches from the spleen, pancreas, and portions of the stomach, and the inferior mesenteric vein. After its formation, the hepatic portal vein also receives branches from the gastric veins of the stomach and cystic veins from the gall bladder. The hepatic portal vein delivers materials from these digestive and circulatory organs directly to the liver for processing. Because of the hepatic portal system, the liver receives its blood supply from two different sources: from normal systemic circulation via the hepatic artery and from the hepatic portal... Q: What organ packages nutrients absorbed by the digestive system; produces plasma proteins, clotting factors, and bile; and disposes of worn-out cell components and waste products? A:
OPTIONS:
- heart
- brain
- liver
- liver
output: liver

Q: Answer the following question given this paragraph: Q: What have cell-surface antigen receptors for foreign molecules? A:

OPTIONS:
- capillaries
- dendrites
- erythrocytes
- lymphocytes

A: lymphocytes

input: OPTIONS:
- weak dominance
- low dominance
- shared dominance
- codominance Now, answer this question: Answer the following question given this paragraph: Codominance is when two alleles are both expressed in the heterozygous individual. Q: What is it called when two alleles are both expressed in the heterozygous individual? A:
A:
output: codominance

Answer the following question given this paragraph: Constriction and dilation allow the circulatory system to change the amount of blood flowing to different organs. For example, during a fight-or-flight response, dilation and constriction of blood vessels allow more blood to flow to skeletal muscles and less to flow to digestive organs. Dilation of blood vessels in the skin allows more blood to flow to the body surface so the body can lose heat. Constriction of these blood vessels has the opposite effect and helps conserve body heat. Q: Constriction and dilation allow the circulatory system to change the amount of blood flowing to which body parts? A:

OPTIONS:
- arteries
- tissues
- muscles
- organs

Answer: organs

Q: Answer the following question given this paragraph: Weight is a measure of the force of gravity pulling down on an object. Buoyant force pushes up on an object. Weight and buoyant force together determine whether an object sinks or floats. This is illustrated in Figure below . Q: What is the measure of the force of gravity pulling down on an object called? A:

OPTIONS:
- factor
- mass
- volume
- weight

A:
weight
