Answer the following question given this paragraph: The first eight phyla listed in Table above include only invertebrate animals. Invertebrates are animals that lack a vertebral column , or backbone . The last phylum in the table, the Chordata, also includes many invertebrate species. Tunicates and lancelets are both invertebrates. Altogether, invertebrates make up at least 95 percent of all animal species. The remaining animals are vertebrates. Vertebrates are animals that have a backbone. All vertebrates belong to the phylum Chordata . They include fish, amphibians, reptiles, birds, and mammals. Q: What is the term for animals that have a backbone? Choices: - carnivores - invertebrates - herbivores - vertebrates A:
vertebrates

Answer the following question given this paragraph: Pictured below is a typical elliptical galaxy ( Figure below ). As you might have guessed, elliptical galaxies are elliptical, or egg-shaped. The smallest elliptical galaxies are as small as some globular clusters. Giant elliptical galaxies can contain over a trillion stars. Elliptical galaxies are reddish to yellowish in color because they contain mostly old stars. Q: What do you call egg-shaped galaxies, which are reddish to yellowish in color because they contain mostly old stars? Choices: - conical galaxies - irregular galaxies - spiral galaxies - elliptical galaxies A:
elliptical galaxies

Answer the following question given this paragraph: Electric potential energy comes from the position of a charged particle in an electric field. For example, when two negative charges are close together, they have potential energy because they repel each other and have the potential to push apart. If the charges actually move apart, their potential energy decreases. Electric charges always move spontaneously from a position where they have higher potential energy to a position where they have lower potential energy. This is like water falling over a dam from an area of higher to lower potential energy due to gravity. Q: What kind of energy comes from the position of a charged particle in an electric field? Choices: - solar energy - mechanical energy - thermal energy - potential energy A:
potential energy

Answer the following question given this paragraph: Producers create food energy. They are the base of all life on Earth. Most producers use photosynthesis but a very small number use chemosynthesis. Q: What is the sun classified as on the main sequence? Choices: - shrinking star - red dwarf - gas giant - yellow dwarf A:
yellow dwarf
