input: OPTIONS:
- intestine
- digestive system
- kidneys
- mouth Now, answer this question: Answer the following question given this paragraph: The mouth is the first organ that food enters. But digestion may start even before you put the first bite of food into your mouth. Just seeing or smelling food can cause the release of saliva and digestive enzymes in your mouth. Q: What is the first digestive organ that food enters? A:
A:
output: mouth

Answer the following question given this paragraph: 19.3 The Human Population Earth's human population is growing exponentially. Humans have increased their carrying capacity through technology, urbanization, and harnessing the energy of fossil fuels. The age structure of a population allows us to predict population growth. Unchecked human population growth could have dire long-term effects on human welfare and Earth's ecosystems. Q: Human population is growing exponentially and humans have increased what normally limiting factor through technology, urbanization, and harnessing the energy of fossil fuels? A:

OPTIONS:
- zero population growth
- mass extinction
- habitat loss
- carrying capacity

Answer: carrying capacity

Problem: OPTIONS:
- Viruses
- Roots
- Bacteria
- fungus
Q: Answer the following question given this paragraph: Humans have collected and grown mushrooms for food for thousands of years. Figure below shows some of the many types of mushrooms that people eat. Yeasts are used in bread baking and brewing alcoholic beverages. Other fungi are used in fermenting a wide variety of foods, including soy sauce, tempeh, and cheeses. Blue cheese has its distinctive appearance and flavor because of the fungus growing though it (see Figure below ). Q: What grows through blue cheese that gives it the distinctive appearance and flavor? A:
Answer: fungus

Problem:OPTIONS:
- primary
- fluorescent
- spectroscopy
- monochromatic

Answer the following question given this paragraph: with only certain radii were allowed. Lines in the spectrum were due to transitions in which an electron moved from a higher-energy orbit with a larger radius to a lower-energy orbit with smaller radius. The orbit closest to the nucleus represented theground state of the atom and was most stable; orbits farther away were higher-energy excited states. Transitions from an excited state to a lower-energy state resulted in the emission of light with only a limited number of wavelengths. Bohr's model could not, however, explain the spectra of atoms heavier than hydrogen. Most light is polychromatic and contains light of many wavelengths. Light that has only a single wavelength is monochromatic and is produced by devices called lasers, which use transitions between two atomic energy levels to produce light in a very narrow range of wavelengths. Atoms can also absorb light of certain energies, resulting in a transition from the ground state or a lower-energy excited state to a higher-energy excited state. This produces an absorption spectrum, which has dark lines in the same position as the bright lines in the emission spectrum of an element. Q: What is light that has only a single wavelength called? A:
****
A: monochromatic
