Answer the following question given this paragraph: Many amino acids can be linked together to form a long chain known as a protein . These linkages are formed when the carboxylic acid of one amino acid reacts with the amine of another to produce an amide (see Figure below ). Q: What is formed when amino acids are linked together in a long chain? A:
****
A: protein

Answer the following question given this paragraph: Minerals that are not just a single element are made of chemical compounds. For example, the mineral quartz is made of the compound silicon dioxide, or SiO 2 . This compound has one atom of the element silicon for every two atoms of the element oxygen. Q: Minerals that are not compounds consist of a single what? A:
OPTIONS:
- electron
- gas
- proton

element

Answer the following question given this paragraph: Many consumers feed at more than one trophic level. Humans, for example, are primary consumers when they eat plants such as vegetables. They are secondary consumers when they eat cows. They are tertiary consumers when they eat salmon. Q: Do most humans feed at one trophic level, or more than one? A:
OPTIONS:
- less than one
- one
- none
- more than one

Answer: more than one

Question: Answer the following question given this paragraph: Alkenes Organic compounds that contain one or more double or triple bonds between carbon atoms are described as unsaturated. You have likely heard of unsaturated fats. These are complex organic molecules with long chains of carbon atoms, which contain at least one double bond between carbon atoms. Unsaturated hydrocarbon molecules that contain one or more double bonds are called alkenes. Carbon atoms linked by a double bond are bound together by two bonds, one bond and one bond. Double and triple bonds give rise to a different geometry around the carbon atom that participates in them, leading to important differences in molecular shape and properties. The differing geometries are responsible for the different properties of unsaturated versus saturated fats. Ethene, C2H4, is the simplest alkene. Each carbon atom in ethene, commonly called ethylene, has a trigonal planar structure. The second member of the series is propene (propylene) (Figure 20.7); the butene isomers follow in the series. Four carbon atoms in the chain of butene allows for the formation of isomers based on the position of the double bond, as well as a new form of isomerism. Q: What are alkenes organic compounds that contain one or more double or triple bonds between carbon atoms described as? A:
OPTIONS:
- saturated
- insulated
- strong
- unsaturated
Answer: unsaturated
