Question: Answer the following question given this paragraph: After the film is developed, any unexposed silver bromide must be removed by a process called "fixing"; otherwise, the entire film would turn black with additional exposure to light. Although silver bromide is insoluble in water, it is soluble in a dilute solution of sodium thiosulfate (Na2S2O3; photographer's hypo) because of the formation of [Ag(S2O3)2]3 ions. Thus washing the film with thiosulfate solution dissolves unexposed silver bromide and leaves a. Q: After the film is developed, any unexposed silver bromide must be removed by a process called what? A:
OPTIONS:
- watering
- sweeping
- washing
- fixing
Answer: fixing

- three
- four Now, answer this question: Answer the following question given this paragraph: Hemoglobin is a compound in the class of compounds called proteins. Proteins are one of four classes of biochemical compounds, which are compounds in living things. (The other three classes are carbohydrates, lipids, and nucleic acids. ) Proteins contain carbon, hydrogen, oxygen, nitrogen, and sulfur. Protein molecules consist of one or more chains of small molecules called amino acids. Q: How many classes of biochemical compounds are there? A:

Answer the following question given this paragraph: Q: Like animals, cyanobacteria possess what kind of biological rhythm? A:

OPTIONS:
- brain rhythm
- music rhythm
- variable rhythm
- circadian rhythm

Answer: circadian rhythm

Q: Answer the following question given this paragraph: Recall that terrestrial biomes are defined by their climate. That's because plants and animals are adapted for certain amounts of temperature and moisture. However, would aquatic biomes be classified in the same way? No, that wouldn't make much senseall parts of an aquatic environment have plenty of water. Aquatic biomes can be generally classified based on the amount of salt in the water. Freshwater biomes have less than 1% salt and are typical of ponds and lakes, streams and rivers, and wetlands. Marine biomes have more salt and are characteristic of the oceans, coral reefs, and estuaries. Q: How are aquatic biomes often classified? A:

OPTIONS:
- depth
- amount of life
- amount of light
- amount of salt

A:
amount of salt
