Answer the following question given this paragraph: Deposition also occurs when a stream or river empties into a large body of still water. In this case, a delta forms. A delta is shaped like a triangle. It spreads out into the body of water. An example is shown in Figure above . Q: What triangular feature is formed when a river empties into a large body of still water? A:
OPTIONS:
- flow
- confluence
- region
- delta

Answer: delta

Question: Answer the following question given this paragraph: Ice is an example of solid matter. A solid is matter that has a fixed volume and a fixed shape. Figure below shows examples of matter that are usually solids under Earth conditions. In the figure, salt and cellulose are examples of crystalline solids. The particles of crystalline solids are arranged in a regular repeating pattern. The steaks and candle wax are examples of amorphous ("shapeless") solids. Their particles have no definite pattern. Q: What is the name for a matter that has a fixed volume and a fixed shape? A:
OPTIONS:
- gas
- stable
- liquid
- solid
Answer: solid

input with options: Answer the following question given this paragraph: Lenses make use of the refraction of light to create images. A lens is a transparent object, typically made of glass, with one or two curved surfaces. The more curved the surface of a lens is, the more it refracts light. Like mirrors, lenses may be concave or convex. Q: Lenses make use of what to create images? A:
OPTIONS:
- envelopment of light
- stimulation of light
- resonance of light
- refraction of light
output: refraction of light

Q: Answer the following question given this paragraph: Small streams often flow into bigger streams or rivers. The small streams are called tributaries. A river and all its tributaries make up a river system. Q: What do a river and all its tributaries make up? A:

OPTIONS:
- abundance system
- water system
- food system
- river system

A: river system

input: OPTIONS:
- shape
- pressure
- color
- energy Now, answer this question: Answer the following question given this paragraph: When physical or chemical changes occur, they are generally accompanied by a transfer of energy. The law of conservation of energy states that in any physical or chemical process, energy is neither created nor destroyed. In other words, the entire energy in the universe is conserved. In order to better understand the energy changes taking place during a reaction, we need to define two parts of the universe, called the system and the surroundings. The system is the specific portion of matter in a given space that is being studied during an experiment or an observation. The surroundings is everything in the universe that is not part of the system. In practical terms for a laboratory chemist, the system is the particular chemicals being reacted, while the surroundings is the immediate vicinity within the room. During most processes, energy is exchanged between the system and the surroundings. If the system loses a certain amount of energy, that same amount of energy is gained by the surroundings. If the system gains a certain amount of energy, that energy is supplied by the surroundings. Q: Physical or chemical changes are generally accompanied by a transfer of what? A:
A:
output: energy

Question: Answer the following question given this paragraph: Mechanical Digestion in the Small Intestine The movement of intestinal smooth muscles includes both segmentation and a form of peristalsis called migrating motility complexes. The kind of peristaltic mixing waves seen in the stomach are not observed here. If you could see into the small intestine when it was going through segmentation, it would look as if the contents were being shoved incrementally back and forth, as the rings of smooth muscle repeatedly contract and then relax. Segmentation in the small intestine does not force chyme through the tract. Instead, it combines the chyme with digestive juices and pushes food particles against the mucosa to be absorbed. The duodenum is where the most rapid segmentation occurs, at a rate of about 12 times per minute. In the ileum, segmentations are only about eight times per minute (Figure 23.20). Q: During what in the small intestine do rings of smooth muscle repeatedly contract and then relax? A:
OPTIONS:
- mitosis
- contraction
- compression
- segmentation
Answer:
segmentation
