Problem:OPTIONS:
- high salt content
- moving water
- animal species
- low salt concentration

Answer the following question given this paragraph: Freshwater biomes are defined by their low salt concentration, usually less than 1%. Plants and animals in freshwater regions are adjusted to the low salt content and would not be able to survive in areas of high salt concentration, such as the ocean. There are different types of freshwater biomes: ponds and lakes ( Figure below ), streams and rivers, and wetlands. Ponds and lakes range in size from just a few square meters to thousands of square kilometers. Streams and rivers are bodies of flowing water moving in one direction. They can be found everywhere. They get their starts at headwaters , which may be springs, melting snow, or even lakes, and then travel all the way to their mouths , emptying into another water channel or the ocean. Wetlands are areas of standing water that support aquatic plants. Wetlands include marshes, swamps, and bogs. Q: What are fresh water biomes defined by? A:
****
A: low salt concentration

Answer the following question given this paragraph: The time interval required for one complete wave to pass a point is called the period . During the period of the wave, an entire wavelength from one crest to the next crest passes a position. The number of waves that pass a single position in one second is called the frequency . The period of a wave and its frequency are reciprocals of each other. Q: What is the time interval required for one complete wave to pass a point called? A:
OPTIONS:
- cycle
- minute
- half-life
- period
period

Answer the following question given this paragraph: Insects are arthropods in the class Hexapoda. They are the most numerous organisms in the world. Q: What are the most numerous organisms in the world? A:
OPTIONS:
- reptiles
- jellyfish
- primates
- insects

Answer: insects

Question: Answer the following question given this paragraph: CHAPTER SUMMARY 42.1 Innate Immune Response The innate immune system serves as a first responder to pathogenic threats that bypass natural physical and chemical barriers of the body. Using a combination of cellular and molecular attacks, the innate immune system identifies the nature of a pathogen and responds with inflammation, phagocytosis, cytokine release, destruction by NK cells, and/or a complement system. When innate mechanisms are insufficient to clear an infection, the adaptive immune response is informed and mobilized. Q: What serves as a first responder to pathogenic threats that bypass natural physical and chemical barriers of the body? A:
OPTIONS:
- cells immune system
- super immune system
- immense immune system
- innate immune system
Answer: innate immune system

input with options: Answer the following question given this paragraph: Much of the iron produced is refined and converted into steel. Steel is made from iron by removing impurities and adding substances such as manganese, chromium, nickel, tungsten, molybdenum, and vanadium to produce alloys with properties that make the material suitable for specific uses. Most steels also contain small but definite percentages of carbon (0.04%2.5%). However, a large part of the carbon contained in iron must be removed in the manufacture of steel; otherwise, the excess carbon would make the iron brittle. Q: Much of the iron produced is refined and converted into what? A:
OPTIONS:
- plastic
- wood
- sugar
- steel
output: steel

Problem: OPTIONS:
- environmental science
- Chemistry
- Thermodynamics
- physical science
Q: Answer the following question given this paragraph: Physical science is the study of matter and energy. It includes the sciences of chemistry and physics. Most careers in physical science require a 4-year college degree in one of these fields. Some careers require more advanced education as well. For example, an astronaut might have a master's degree or even a doctoral degree. Q: What branch of science is the study of matter and energy? A:
Answer:
physical science
