input with options: Answer the following question given this paragraph: Matter is anything that occupies space and has mass. The three states of matter are solid, liquid, and gas. A physical change involves the conversion of a substance from one state of matter to another, without changing its chemical composition. Most matter consists of mixtures of pure substances, which can behomogeneous (uniform in composition) or heterogeneous (different regions possess different compositions and properties). Pure substances can be either chemical compounds or elements. Compounds can be broken down into elements by chemical reactions, but elements cannot be separated into simpler substances by chemical means. The properties of substances can be classified as either physical or chemical. Scientists can observe physical properties without changing the composition of the substance, whereas chemical propertiesdescribe the tendency of a substance to undergo chemical changes (chemical reactions) that change its chemical composition. Physical properties can be intensive or extensive. Intensive properties are the same for all samples; do not depend on sample size; and include, for example, color, physical state, and melting and boiling points. Extensive properties depend on the amount of material and include mass and volume. The ratio of two extensive properties, mass and volume, is an important intensive property called density. Q: What term describes anything that occupies space and has mass, and is generally divided into three states? A:
OPTIONS:
- stuff
- lquid
- galaxy
- matter
output: matter

Q: Answer the following question given this paragraph: Q: Similarity that results from common ancestry is known as what? A:

OPTIONS:
- affinity
- heterogeny
- duality
- homology

A: homology

input: OPTIONS:
- barking
- sweating
- eating
- panting Now, answer this question: Answer the following question given this paragraph: One way mammals lose excess heat is by increasing blood flow to the skin. This warms the skin so heat can be given off to the environment. That's why you may get flushed, or red in the face, when you exercise on a hot day. You are likely to sweat as well. Sweating also reduces body heat. Sweat wets the skin, and when it evaporates, it cools the body. Evaporation uses energy, and the energy comes from body heat. Animals with fur, such as dogs, use panting instead of sweating to lose body heat (see Figure below ). Evaporation of water from the tongue and other moist surfaces of the mouth and throat uses heat and helps cool the body. Q: How do dogs lose body heat? A:
A:
output: panting

Answer the following question given this paragraph: There are six types of quarks . In ordinary matter, virtually all quarks are of the types called up and down quarks. All quarks have mass, and they have an electric charge of either +2/3 or -1/3. For example, up quarks have a charge of +2/3, and down quarks have a charge of -1/3. Quarks also have a different type of charge, called color charge, although it has nothing to do with the colors that we see. Quarks are never found alone but instead always occur in groups of two or three quarks. Q: Quarks also have a different type of charge, called what? A:

OPTIONS:
- contrast charge
- pure charge
- spontaneous charge
- color charge

Answer: color charge

Problem: OPTIONS:
- clones
- genomes
- replicants
- genes
Q: Answer the following question given this paragraph: The DNA of a chromosome is encoded with genetic instructions for making proteins. These instructions are organized into units called genes . Most genes contain the instructions for a single protein. There may be hundreds or even thousands of genes on a single chromosome. Q: What are the organized instructions within dna for making proteins called? A:
Answer: genes

Answer the following question given this paragraph: Acceleration is a measure of the change in velocity of a moving object. It shows how quickly velocity changes and whether the change is positive or negative. It may reflect a change in speed, a change in direction, or both. Q: What is a measure of the change in velocity of a moving object? A:

OPTIONS:
- inclination
- vibration
- kinetic energy
- acceleration

Answer:
acceleration
