input with options: Answer the following question given this paragraph: Another interesting feature of many cnidarians is the ability to produce light. The production of light by living things is called bioluminescence. A more familiar example of bioluminescence is the light produced by fireflies. In cnidarians, bioluminescence may be used to startle predators or to attract prey or mates. Watch this short video to see an amazing light show put on by a jellyfish at the Monterey Aquarium in Monterey, California: https://www. youtube. com/watch?v=kdufLq2P1Ag . Q: The production of light by living things is called what? A:
OPTIONS:
- apoptosis
- attenuation
- bio-glow
- bioluminescence
output: bioluminescence

Q: Answer the following question given this paragraph: The atria receive the blood, and the ventricles pump the blood out of the heart. Each of the four chambers of the heart has a specific job. Q: How many chambers are in the heart? A:

OPTIONS:
- two
- eight
- five
- four

A: four

input: OPTIONS:
- mitosis
- contraction
- compression
- segmentation Now, answer this 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:
A:
output: segmentation

Answer the following question given this paragraph: To understand the differences between nuclear fission and fusion. Nuclear reactions, like chemical reactions, are accompanied by changes in energy. The energy changes in nuclear reactions, however, are enormous compared with those of even the most energetic chemical reactions. In fact, the energy changes in a typical nuclear reaction are so large that they result in a measurable change of mass. In this section, we describe the relationship between mass and energy in nuclear reactions and show how the seemingly small changes in mass that accompany nuclear reactions result in the release of enormous amounts of energy. Q: The energy changes in what reactions are enormous compared with those of even the most energetic chemical reactions, and they result in a measurable change of mass? A:

OPTIONS:
- molecular reaction
- metabolic reaction
- methane combustion
- nuclear reactions

Answer: nuclear reactions

Problem: OPTIONS:
- alkaline ions
- synthesis ions
- ingredient ions
- hydroxide ions
Q: Answer the following question given this paragraph: Acids are ionic compounds that produce positively charged hydrogen ions (H + ) when dissolved in water. Acids taste sour and react with metals. Bases are ionic compounds that produce negatively charged hydroxide ions (OH - ) when dissolved in water. Bases taste bitter and do not react with metals. Examples of acids are vinegar and battery acid. The acid in vinegar is weak enough to safely eat on a salad. The acid in a car battery is strong enough to eat through skin. Examples of bases include those in antacid tablets and drain cleaner. Bases in antacid tablets are weak enough to take for an upset stomach. Bases in drain cleaner are strong enough to cause serious burns. Q: What is produced when a base is dissolved in water? A:
Answer: hydroxide ions

Answer the following question given this paragraph: Cell division is how organisms grow and repair themselves. It is also how many organisms produce offspring. For many single-celled organisms, reproduction is a similar process. The parent cell simply divides to form two daughter cells that are identical to the parent. In many other organisms, two parents are involved, and the offspring are not identical to the parents. In fact, each offspring is unique. Look at the family in Figure below . The children resemble their parents, but they are not identical to them. Instead, each has a unique combination of characteristics inherited from both parents. Q: How do organisms grow and repair themselves? A:

OPTIONS:
- cell death
- mutation
- symbosis
- cell division

Answer:
cell division
