Question: Answer the following question given this paragraph: Kinetic energy is the energy of motion. Any object that is moving possesses kinetic energy. Baseball involves a great deal of kinetic energy. The pitcher throws a ball, imparting kinetic energy to the ball. When the batter swings, the motion of swinging creates kinetic energy in the bat. The collision of the bat with the ball changes the direction and speed of the ball, with the idea of kinetic energy being involved again. Q: What energy is the energy of motion? A:
OPTIONS:
- optimal
- potential
- thermal
- kinetic
Answer: kinetic

input with options: Answer the following question given this paragraph: A molecule is any combination of two or more atoms. The oxygen in the air we breathe is two oxygen atoms connected by a chemical bond to form O 2 , or molecular oxygen. A carbon dioxide molecule is a combination of one carbon atom and two oxygen atoms, CO 2 . Because carbon dioxide includes two different elements, it is a compound as well as a molecule. Q: What term is used for any combination of two or more atoms? A:
OPTIONS:
- element
- synthesis
- nucleus
- molecule
output: molecule

Q: Answer the following question given this paragraph: For photosynthesis, stomata must control the transpiration of water vapor and the exchange of carbon dioxide and oxygen. Stomata are flanked by guard cells that swell or shrink by taking in or losing water through osmosis. When they do, they open or close the stomata. Q: Stomata must control the transpiration of water vapor and the exchange of carbon dioxide and oxygen that take place during what process? A:

OPTIONS:
- glycolysis
- spermatogenesis
- fertilization
- photosynthesis

A: photosynthesis

input: OPTIONS:
- a toxic reaction
- a bio reaction
- a thermodynamic reaction
- a chemical reaction Now, answer this question: Answer the following question given this paragraph: A chemical reaction is a process in which some substances change into different substances. In a chemical reaction, bonds break in reactants and new bonds form in products. Q: What is a process in which some substances change into different substances? A:
A:
output: a chemical reaction

Answer the following question given this paragraph: When a blood vessel constricts, less blood can flow through it. Q: Does blood flow increase or decrease when blood vessels constrict? A:

OPTIONS:
- it's not affected
- increases
- it stops
- decrease

Answer: decrease

Q: Answer the following question given this paragraph: 2.3 Chemical Reactions Chemical reactions, in which chemical bonds are broken and formed, require an initial investment of energy. Kinetic energy, the energy of matter in motion, fuels the collisions of atoms, ions, and molecules that are necessary if their old bonds are to break and new ones to form. All molecules store potential energy, which is released when their bonds are broken. Four forms of energy essential to human functioning are: chemical energy, which is stored and released as chemical bonds are formed and broken; mechanical energy, which directly powers physical activity; radiant energy, emitted as waves such as in sunlight; and electrical energy, the power of moving electrons. Chemical reactions begin with reactants and end with products. Synthesis reactions bond reactants together, a process that requires energy, whereas decomposition reactions break the bonds within a reactant and thereby release energy. In exchange reactions, bonds are both broken and formed, and energy is exchanged. The rate at which chemical reactions occur is influenced by several properties of the reactants: temperature, concentration and pressure, and the presence or absence of a catalyst. An enzyme is a catalytic protein that speeds up chemical reactions in the human body. Q: What term is used to describe the energy of matter in motion? A:

OPTIONS:
- frictional energy
- gravitational energy
- emotional energy
- kinetic energy

A:
kinetic energy
