Answer the following question given this paragraph: Nuclear fission is the splitting of the nucleus of a radioactive atom into two smaller nuclei. This type of reaction releases a great deal of energy from a very small amount of matter. Fission of a tiny pellet of radioactive uranium-235, like the one pictured in the Figure below , releases as much energy as burning 1,000 kilograms of coal!. Q: Splitting of the nucleus of a radioactive atom into two smaller nuclei yields what type of reaction, which releases a great deal of energy from a small amount of matter? A:
OPTIONS:
- solar fission
- nucleation
- nuclear fusion
- nuclear fission

Answer: nuclear fission

Question: Answer the following question given this paragraph: (a) When pyrimidine or purine and a sugar react to form a glycosidic bond, a nucleoside is produced. Adding a phosphoric acid group to the sugar of a nucleoside produces a nucleotide. (b) Nucleotides link together to form long polymeric chains. A DNA molecule consists of two such chains held together by hydrogen bonding between the purine and pyrimidine components on different chains. Mutations in the DNA of an organism may lead to the synthesis of defective proteins. Phenylketonuria (PKU), for example, is a condition caused by a defective enzyme. Left. Q: What links together to form long polymeric chains? A:
OPTIONS:
- genes
- lipids
- peptides
- nucleotides
Answer: nucleotides

input with options: Answer the following question given this paragraph: Regular reflection occurs when light reflects off a very smooth surface and forms a clear image. Diffuse reflection occurs when light reflects off a rough surface and forms a blurry image or no image at all. Q: What occurs when light reflects off a very smooth surface and forms a clear image? A:
OPTIONS:
- projection
- absorption
- refraction
- regular reflection
output: regular reflection

Q: Answer the following question given this paragraph: Water flows through all the world's oceans. Warm water from the Equator mixes with cold water from the poles. The mixing of warm and cold water makes the water temperature moderate. Q: Which water from the equator mixes with cold water from the poles? A:

OPTIONS:
- spring water
- hot
- ice water
- warm

A: warm

Answer the following question given this paragraph: Q: What is the lowest level of organization that can perform all activities required for life? A:
