Answer the following question given this paragraph: In benzene, the true bonding between carbon atoms is neither a single nor a double bond. Rather, all of the bonds are a hybrid of a single and double bond. In benzene, the pi bonding electrons are free to move completely around the ring. Delocalized electrons are electrons that are not confined to the bond between two atoms, but are instead allowed to move between three or more. The delocalization of the electrons in benzene can best be shown by showing benzene with a ring inside the hexagon, with the hydrogen atoms understood. Q: What type of electrons are electrons that are not confined to the bond between two atoms? A:
OPTIONS:
- virtualized
- detached
- internalized
- delocalized

Answer: delocalized

Question: Answer the following question given this paragraph: Q: What is the spread of cancer cells beyond their original site called? A:
OPTIONS:
- scattering
- mutations
- apoptosis
- metastasis
Answer: metastasis

input with options: Answer the following question given this paragraph: The second stage of photosynthesis takes place in the stroma surrounding the thylakoid membranes of the chloroplast. The reactions of this stage can occur without light, so they are sometimes called light-independent or dark reactions. This stage of photosynthesis is also known as the Calvin cycle because its reactions were discovered by a scientist named Melvin Calvin. He won a Nobel Prize in 1961 for this important discovery. Q: Which cycle is named after the scientist melvin calvin? A:
OPTIONS:
- krebs cycle
- melvin cycle
- melcal cycle
- calvin cycle
output: calvin cycle

Q: Answer the following question given this paragraph: The most important difference between synthetic and naturally occurring polymers is that the former usually contain very few different monomers, whereas biological polymers can have as many as 20 different kinds of amino acid residues arranged in many different orders. Chains with less than about 50 amino acid residues are calledpeptides, whereas those with more than about 50 amino acid residues are calledproteins. Many proteins are enzymes, which are catalysts that increase the rate of a biological reaction. Q: What role do proteins play in a biological reaction? A:

OPTIONS:
- amino acid chains
- antioxidants
- reverse hormones
- act as catalysts

A: act as catalysts

input: OPTIONS:
- isotopic decay
- radioactive decrease
- secondary decay
- radioactive decay Now, answer this question: Answer the following question given this paragraph: Radioactive decay is the breakdown of unstable isotopes into stable elements. For example, carbon-14 is an unstable isotope of carbon that decays to the stable element nitrogen-14. The rate of decay of an isotope is measured in half-lives. A half-life is the time it takes for half a given amount of an isotope to decay. Q: What is the term for the breakdown of unstable isotopes into stable elements? A:
A:
output: radioactive decay

Question: Answer the following question given this paragraph: A cyclic hydrocarbon is a hydrocarbon in which the carbon chain joins to itself in a ring. A cycloalkane is a cyclic hydrocarbon in which all of the carbon-carbon bonds are single bonds. Like other alkanes, cycloalkanes are saturated compounds. Cycloalkanes have the general formula of C n H 2n . The simplest cycloalkane is cyclopropane, a three-carbon ring. Q: What is a hydrocarbon in which the carbon chain joins to itself in a ring? A:
OPTIONS:
- asymmetrical hydrocarbon
- circular hydrocarbon
- acid hydrocarbon
- cyclic hydrocarbon
Answer:
cyclic hydrocarbon
