- abundance
- kilocalorie
- molarity
molarity

Answer the following question given this paragraph: The electrical conductivity of a substance is a property that depends only on the type of substance. Silver, gold, and copper are excellent conductors of electricity, while glass and plastic are poor conductors. A larger or smaller piece of glass will not change this property. An intensive property is a property of matter that depends only on the type of matter in a sample and not on the amount. Other intensive properties include color, temperature, density, and solubility. Q: Silver, gold, and copper all conduct what very well? A:
OPTIONS:
- light
- sound
- microwaves
- electricity

Answer: electricity

Question: Answer the following question given this paragraph: Many drugs affect the brain and influence how a person feels, thinks, or acts. Such drugs are called psychoactive drugs. They include legal drugs such as caffeine and alcohol, as well as illegal drugs such as cocaine and heroin. They also include certain medicines, such as antidepressant drugs and medical marijuana. Q: What types of drugs affect the brain and influence how a person can feel, think, or act? A:
OPTIONS:
- antibiotics
- analgesics
- prescription
- psychoactive
Answer: psychoactive

input with options: Answer the following question given this paragraph: saliva. Although there may be a tendency to think that mechanical digestion is limited to the first steps of the digestive process, it occurs after the food leaves the mouth, as well. The mechanical churning of food in the stomach serves to further break it apart and expose more of its surface area to digestive juices, creating an acidic "soup" called chyme. Segmentation, which occurs mainly in the small intestine, consists of localized contractions of circular muscle of the muscularis layer of the alimentary canal. These contractions isolate small sections of the intestine, moving their contents back and forth while continuously subdividing, breaking up, and mixing the contents. By moving food back and forth in the intestinal lumen, segmentation mixes food with digestive juices and facilitates absorption. In chemical digestion, starting in the mouth, digestive secretions break down complex food molecules into their chemical building blocks (for example, proteins into separate amino acids). These secretions vary in composition, but typically contain water, various enzymes, acids, and salts. The process is completed in the small intestine. Food that has been broken down is of no value to the body unless it enters the bloodstream and its nutrients are put to work. This occurs through the process of absorption, which takes place primarily within the small intestine. There, most nutrients are absorbed from the lumen of the alimentary canal into the bloodstream through the epithelial cells that make up the mucosa. Lipids are absorbed into lacteals and are transported via the lymphatic vessels to the bloodstream (the subclavian veins near the heart). The details of these processes will be discussed later. In defecation, the final step in digestion, undigested materials are removed from the body as feces. Q: Mechanical churning of food in what organ serves to further break it apart and expose more of its surface area to digestive juices, creating an acidic "soup" called chyme? A:
OPTIONS:
- liver
- kidneys
- gall bladder
- stomach
output: stomach

Q: Answer the following question given this paragraph: Figure 20.11 Carbon dioxide gas exists in the atmosphere and is dissolved in water. Photosynthesis converts carbon dioxide gas to organic carbon, and respiration cycles the organic carbon back into carbon dioxide gas. Long-term storage of organic carbon occurs when matter from living organisms is buried deep underground and becomes fossilized. Volcanic activity and, more recently, human emissions bring this stored carbon back into the carbon cycle. (credit: modification of work by John M. Evans and Howard Perlman, USGS). Q: Long-term storage of what element occurs when matter from living organisms is buried deep underground and becomes fossilized? A:

OPTIONS:
- oxygen
- Nitrogen
- hydrogen
- carbon

A: carbon

Answer the following question given this paragraph: Figure 26.8 illustrates the life cycle of a conifer. The sporophyte (2n) phase is the longest phase in the life of a gymnosperm. The gametophytes (1n)microspores and megasporesare reduced in size. It may take more than year between pollination and fertilization while the pollen tube grows towards the megasporocyte (2n), which undergoes meiosis into megaspores. The megaspores will mature into eggs (1n). Q: The sporophyte phase is the longest phase in the life of what? A:
OPTIONS:
- echinoderm
- arthropod
- angiosperm
- gymnosperm
gymnosperm
