Answer the following question given this paragraph: All atoms of the same element have the same number of protons, but some may have different numbers of neutrons. For example, all carbon atoms have six protons, and most have six neutrons as well. But some carbon atoms have seven or eight neutrons instead of the usual six. Atoms of the same element that differ in their numbers of neutrons are called isotopes . Many isotopes occur naturally. Usually one or two isotopes of an element are the most stable and common. Different isotopes of an element generally have the same physical and chemical properties. That's because they have the same numbers of protons and electrons. For a video explanation of isotopes, go to this URL:. Q: What is the name of an element with a different number of neutrons? Choices: - mineral - reaction - solution - isotope A:

Answer the following question given this paragraph: The nucleus of many cells also contains a central region called the nucleolus . The job of the nucleolus is to build ribosomes. These ribosomes flow out the nuclear pores into the cytoplasm. Ribosomes are organelles that make proteins in the cytoplasm. See the composition of the nucleus pictured below ( Figure below ). Q: The job of the nucleolus is to build what? Choices: - chromosomes - electrons - cells - ribosomes A:
ribosomes

Answer the following question given this paragraph: Roundworms have a tough covering of cuticle on the surface of their body. It prevents their body from expanding. This allows the buildup of fluid pressure in their partial body cavity. The fluid pressure adds stiffness to the body. This provides a counterforce for the contraction of muscles, allowing roundworms to move easily over surfaces. Q: Which body part helps roundworm prevent their body from expanding? Choices: - scales - plate - skin - tough cuticle covering A:
tough cuticle covering
