Answer the following question given this paragraph: 2.3 Scientific method The scientific method is not a step by step, linear process. It is an intuitive process, a methodology for learning about the world through the application of knowledge. Scientists must be able to have an "imaginative preconception" of what the truth is. Scientists will often observe and then hypothesize the reason why a phenomenon occurred. They use all of their knowledge and a bit of imagination, all in an attempt to uncover something that might be true. A typical scientific investigation might go like so: You observe that a room appears dark, and you ponder why the room is dark. In an attempt to find explanations to this curiosity, your mind unravels several different hypotheses. One hypothesis might state that the lights are turned off. Another hunch might be that the room's lightbulb has burnt out. Worst yet, you could be going blind. To discover the truth, 10 11 12 13 14. Q: Scientists will often observe and then what the reason why a phenomenon occurred? Choices: - realize - normalize - theorize - hypothesize A:
hypothesize
Answer the following question given this paragraph: Carbon from decaying organisms enters the ground. Some carbon is stored in the soil. Some carbon may be stored underground for millions of years. This will form fossil fuels. When volcanoes erupt, carbon from the mantle is released as carbon dioxide into the air. Producers take in the carbon dioxide to make food. Then the cycle repeats. Q: When volcanoes erupt, what from the mantle is released as carbon dioxide into the air? Choices: - lava - hydrogen - vapor - carbon A:
carbon
Q: Answer the following question given this paragraph: A lichen is a mutualistic relationship between a fungus and a photosynthetic organism. The other organism is usually a cyanobacterium or green alga. The fungus grows around the bacterial or algal cells. The fungus benefits from the constant supply of food produced by the photosynthesizer. The photosynthesizer benefits from the water and nutrients absorbed by the fungus. Figure below shows lichen growing on a rock. Q: The fungus benefits from the constant supply of food produced by what? Choices: - the host - the spermatophyte - the phytoflagellate - the photosynthesizer A:
A: the photosynthesizer
Question: Answer the following question given this paragraph: Kidney stones are mineral crystals that form in urine inside the kidney. They may be extremely painful. If they block a ureter, they must be removed so urine can leave the kidney and be excreted. Q: What kind of health problem can occur in the kidney and potentially cause problems with urination? Choices: - infection - diabetes - gallstones - kidney stones A:
Answer: kidney stones
*Question*
Answer the following question given this paragraph: An antibody matches only one type of antigen. Q: How many types of antigens can an antibody match? Choices: - two - four - infinite - one A:
**Answer**
one
Q: Answer the following question given this paragraph: The nuclei that are to the left or to the right of the band of stability are unstable and exhibit radioactivity. They change spontaneously (decay) into other nuclei that are either in, or closer to, the band of stability. These nuclear decay reactions convert one unstable isotope (or radioisotope) into another, more stable, isotope. We will discuss the nature and products of this radioactive decay in subsequent sections of this chapter. Several observations may be made regarding the relationship between the stability of a nucleus and its structure. Nuclei with even numbers of protons, neutrons, or both are more likely to be stable (see Table 21.1). Nuclei with. Q: Nuclei with even numbers of protons, neutrons, or both are more likely to be this? Choices: - ionic - solid - unstable - stable A:
A: stable
