Answer the following question given this paragraph: Metalloids are elements that have properties of both metals and nonmetals. Some can conduct electricity but only at certain temperatures. They may be shiny but brittle. All metalloids are solids at room temperature. Q: Elements that specifically are noted to have properties of both metals and nonmetals are known as what? Choices: - compund metals - alloys - alkali metals - metalloids A:
metalloids
Answer the following question given this paragraph: An electric field is a space around a charged particle where the particle exerts electric force on other charged particles. Because of their force fields, charged particles can exert force on each other without actually touching. Electric fields are generally represented by arrows, as you can see in the Figure below . The arrows show the direction of electric force around a positive particle and a negative particle.

Q: What do you call the space around a charged particle where the particle exerts electric force on other charged particles? Choices: - melodic field - powered field - charged field - electric field A:
electric field
Q: Answer the following question given this paragraph: Comets are small, icy objects that orbit the Sun in very elliptical orbits. When they are close to the Sun, they form comas and tails, which glow and make the comet more visible. Q: What types of orbits do comets usually have? Choices: - vertical - convex - spectral - elliptical A:
A: elliptical
Question: Answer the following question given this paragraph: In the predator-prey example, one factor limits the growth of the other factor. As the prey population deceases, the predator population is begins to decrease as well. The prey population is a limiting factor. A limiting factor limits the growth or development of an organism, population, or process. Q: What is the term for something that limits the growth or development of an organism, population, or process? Choices: - controlling factor - stumbling block - variable - limiting factor A:
Answer: limiting factor

Answer the following question given this paragraph: Chymotrypsin is found in the small intestine and catalyzes the hydrolysis of peptide bonds following aromatic amino acids. Lactase is found in the small intestine and catalyzes the hydrolysis of lactose. Pepsin is found in the stomach and catalyzes the hydrolysis of peptide bonds, primarily those that occur after aromatic amino acids. Maltase is found in the small intestine and catalyzes the hydrolysis of maltose. Q: What enzyme is found in the small intestine catalyzes the hydrolysis of lactose? Choices: - elastases - lipase - amylase - lactase A:
(Answer)
lactase
