input with options: Answer the following question given this paragraph: The pupil is an opening in the front of the eye. It looks black because it doesn't reflect any light. All the light passes through it instead. The pupil controls the amount of light that enters the eye. It automatically gets bigger or smaller to let more or less light in as needed. Q: What is the opening in the front of the eye called? A:
OPTIONS:
- lens
- cornea
- iris
- pupil
output: pupil

Q: Answer the following question given this paragraph: The smallest particle of an element that still has the properties of that element is an atom. Atoms are extremely tiny. They can be observed only with an electron microscope. They are commonly represented by models, like the one Figure below . An atom has a central nucleus that is positive in charge. The nucleus is surrounded by negatively charged particles called electrons. Q: What is the smallest particle of an element that still has the properties of that element is called? A:

OPTIONS:
- nucleus
- neutron
- proton
- atom

A: atom

input: OPTIONS:
- carbon monoxide
- nitrogen
- ozone
- carbon dioxide Now, answer this question: Answer the following question given this paragraph: 6O 2 + C 6 H 12 O 6 6CO 2 + 6H 2 O Photosynthesis produces oxygen as a byproduct, and respiration produces carbon dioxide as a byproduct. In nature, there is no such thing as waste. Every single atom of matter is conserved, recycling indefinitely. Substances change form or move from one type of molecule to another, but never disappear (Figure 5.18). CO2 is no more a form of waste produced by respiration than oxygen is a waste product of photosynthesis. Both are byproducts of reactions that move on to other reactions. Photosynthesis absorbs energy to build carbohydrates in chloroplasts, and aerobic cellular respiration releases energy by using oxygen to break down carbohydrates. Both organelles use electron transport chains to generate the energy necessary to drive other reactions. Photosynthesis and cellular respiration function in a biological cycle, allowing organisms to access life-sustaining energy that originates millions of miles away in a star. Q: Photosynthesis produces oxygen as a byproduct, and respiration produces what as a byproduct? A:
A:
output: carbon dioxide

Q: Answer the following question given this paragraph: Ribosomes are cellular substructures where proteins are synthesized. They contain about 65% rRNA and 35% protein, held together by numerous noncovalent interactions, such as hydrogen bonding, in an overall structure consisting of two globular particles of unequal size. Molecules of tRNA, which bring amino acids (one at a time) to the ribosomes for the construction of proteins, differ from one another in the kinds of amino acid each is specifically designed to carry. A set of three nucleotides, known as a codon, on the mRNA determines which kind of tRNA will add its amino acid to the growing chain. (For more information on sequences, see Section 19.4 "Protein Synthesis and the Genetic Code". ) Each of the 20 amino acids found in proteins has at least one corresponding kind of tRNA, and most amino acids have more than one. The two-dimensional structure of a tRNA molecule has three distinctive loops, reminiscent of a cloverleaf (Figure 19.11 "Transfer RNA"). On one loop is a sequence of three nucleotides that varies for each kind of tRNA. This triplet, called the anticodon, is complementary to and pairs with the codon on the mRNA. At the opposite end of the molecule is the acceptor stem, where the amino acid is attached. Figure 19.11 Transfer RNA Saylor URL: http://www. saylor. org/books. Q: Ribosomes are cellular substructures where what are synthesized? A:
Answer: proteins
