Answer the following question given this paragraph: The first species to colonize a disturbed area such as this are called pioneer species (see Figure below ). They change the environment and pave the way for other species to come into the area. Pioneer species are likely to include bacteria and lichens that can live on bare rock. Along with wind and water, they help weather the rock and form soil. Once soil begins to form, plants can move in. At first, the plants include grasses and other species that can grow in thin, poor soil. As more plants grow and die, organic matter is added to the soil. This improves the soil and helps it hold water. The improved soil allows shrubs and trees to move into the area. Q: What are species that are first to colonize a disturbed area called? Choices: - novel species - exploratory species - brave species - pioneer species A:
pioneer species

Answer the following question given this paragraph: Compressibility is the measure of how much a given volume of matter decreases when placed under pressure. If we put pressure on a solid or a liquid, there is essentially no change in volume. The atoms, ions, or molecules that make up the solid or liquid are very close together. There is no space between the individual particles, so they cannot pack together. Q: The measure of how much a given volume of matter decreases when placed under pressure is called? Choices: - elasticity - solubility - malleability - compressibility A:
compressibility
