Question: Answer the following question given this paragraph: Most substances have three distinct phases: gas, liquid, and solid. Phase changes among the various phases of matter depend on temperature and pressure. The existence of the three phases with respect to pressure and temperature can be described in a phase diagram. Two phases coexist (i. , they are in thermal equilibrium) at a set of pressures and temperatures. These are described as a line on a phase diagram. The three phases coexist at a single pressure and temperature. This is known as the triple point and is described by a single point on a phase diagram. A gas at a temperature below its boiling point is called a vapor. Vapor pressure is the pressure at which a gas coexists with its solid or liquid phase. Partial pressure is the pressure a gas would create if it existed alone. Dalton's law states that the total pressure is the sum of the partial pressures of all of the gases present. Q: Temperature and pressure affect changes in phases or states of what? A:
OPTIONS:
- homeostasis
- decay
- energy
- matter
Answer: matter

input with options: Answer the following question given this paragraph: When current keeps reversing direction, it is called alternating current (AC) . You can see how it works in the two diagrams below. The current that comes from a power plant and supplies electricity to homes and businesses is alternating current. The current changes direction 60 times per second. It happens so quickly that the light bulb doesn't have a chance to stop glowing when the reversals occur. Q: What is it called when currents keep reversing direction? A:
OPTIONS:
- circle current
- emitting current
- stream current
- alternating current
output: alternating current

Q: Answer the following question given this paragraph: 16 Gregor Mendel and biological inheritance Charles Darwin1 , for all he contributed to the science of biology, never knew about the mechanism by which living things inherit traits from previous generations, or how new traits arise. As any schoolchild can tell you, this mechanism of interitance has since been found to be DNA2 , or deoxyribonucleic acid. DNA allows for stable inheritance of traits: the code in each strand of DNA is replicated precisely through the pairing of basic units along each strand. The error rate in this replication is amazingly low; not even one base pair in a million matches out of sequence. However, when even one base pair is added to a new strain of DNA in an order differently than in the parent chain, it can be the basis of a mutation. These changes in DNA sequences are the microscopic origin of changes in traits of all studied living things. Even the smallest difference in a strand of DNA can result in a change in traits that can cost the life of the organism. Mutations can produce proteins with a new or altered function. In humans, the example of Sickle cell anemia3 is commonly given as its origin is a difference of only one base pair in a section of DNA that encodes red blood cells. Individual sequences of DNA that encode for specific proteins are called genes and are the units of heredity. Each one has a set nucleotide4 , and together all of the genes (and some sequence of DNA that apparently do not code for any biologically important functions) together make up the entire chromosome5. Q: What mechanism is used by living organisms to pass along genes? A:

OPTIONS:
- protein
- digestion
- chlorophyll
- dna

A: dna

input: OPTIONS:
- momentous
- monomers
- hypochlorous
- adventitious Now, answer this question: Answer the following question given this paragraph: the radicle is also growing and producing the primary root. As it grows downward to form the tap root, lateral roots branch off to all sides, producing the typical dicot tap root system. In monocot seeds (Figure 32.21), the testa and tegmen of the seed coat are fused. As the seed germinates, the primary root emerges, protected by the root-tip covering: the coleorhiza. Next, the primary shoot emerges, protected by the coleoptile: the covering of the shoot tip. Upon exposure to light (i. when the plumule has exited the soil and the protective coleoptile is no longer needed), elongation of the coleoptile ceases and the leaves expand and unfold. At the other end of the embryonic axis, the primary root soon dies, while other, adventitious roots (roots that do not arise from the usual place i. the root) emerge from the base of the stem. This gives the monocot a fibrous root system. Q: What is root that does not arise from a usual place? A:
A:
output: adventitious

Answer the following question given this paragraph: Microevolution is the process by which organisms change in small ways over time. Q: What is the process by which organisms change in small ways over time? A:

OPTIONS:
- spontaneous mutation
- natural selection
- adaptation
- microevolution

Answer: microevolution

Q: Answer the following question given this paragraph: Energy in a body of water can be gained or lost depending on conditions. When water is heated above a certain temperature steam is generated. The increase in heat energy creates a higher level of disorder in the water molecules as they boil off and leave the liquid. Q: What do you need to do to water to make it steam? A:

OPTIONS:
- freeze it
- stir it
- cool it
- heat it

A:
heat it
