Answer the following question given this paragraph: If a solute is a gas, increasing the temperature decreases its solubility. For example, less carbon dioxide can dissolve in warm ocean water than in cold ocean water. Q: If a solute is a gas, increasing the temperature will do what? Choices: - increase its solubility - have no effect - change to liquid - decrease its solubility A:
decrease its solubility
Answer the following question given this paragraph: As shown in Figure above , each state of matter looks quite different at the molecular level. In the case of liquids and solids, the distances between particles are negligible relative to the size of each particle; they are essentially in direct contact with one another. In liquids, particles are free to move and exchange neighbors, resulting in the properties of a fluid. In solids, they are rigidly fixed in space and held tightly to neighboring particles. Q: In what state of matter are particles rigidly fixed in space and held tightly to neighboring particles? Choices: - Gases - liquids - energies - solids A:
solids
Q: Answer the following question given this paragraph: The two photos in Figure above represent two different biomes. A biome is a group of similar ecosystems with the same general abiotic factors and primary producers. Producers are organisms that produce food for themselves and other organisms. Biomes may be terrestrial or aquatic. Q: What is a group of similar ecosystems with the same general abiotic factors and primary producers? Choices: - ecoregion - family - taxon - biome A:
A: biome
Question: Answer the following question given this paragraph: Antibodies These proteins recognize and combine with harmful materials, including both toxic chemicals and invasive microorganisms (such as bacteria and viruses). When an antibody binds to its target, it is tagged for destruction. This tag is recognized by white blood cells, which complete the process. Some antibodies also partially or completely deactivate their targets while waiting for further help from white blood cells. Q: Which proteins recognize and combine with harmful materials, including both toxic chemicals and invasive microorganisms? Choices: - enzymes - collagen - essential amino acids - antibodies A:
Answer: antibodies

Answer the following question given this paragraph: The driving force to combine with nonmetals to create ionic compounds varies quite a bit between different metals. Some pure metals, like cesium and potassium, are so eager to react that they must be stored under oil to avoid an immediate reaction with the oxygen present in air. Others, like platinum and gold, are stable enough that they can be found in nature as pure metals rather than as the cationic portion of an ionic compound. Gradual degradation of a material due to its exposure to the environment is known as corrosion . Metals like gold and platinum are unusually resistant to corrosion, which makes them especially valuable for both structural and decorative purposes. Q: Gradual degradation of a material due to its exposure to the environment is known as what? Choices: - metabolism - erosion - destruction - corrosion A:
**Answer**
corrosion

Answer the following question given this paragraph: Members of the genus Trypanosoma are flagellate protozoa that cause sleeping sickness , which is common in Africa. They also cause Chagas disease , which is common in South America. The parasites are spread by insect vectors. The vector for Chagas disease is shown in Figure below . Trypanosoma parasites enter a person's blood when the vector bites. Then they spread to other tissues and organs. The diseases may be fatal without medical treatment. Q: Members of the genus trypanosoma are flagellate protozoa that cause what? Choices: - cancer - hypertension - mutations - sleeping sickness A:
**Answer**
sleeping sickness
