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
Answer the following question given this paragraph: The rock in Figure above is an example of a heterogeneous mixture. A heterogeneous mixture varies in its composition. The black nuggets, for example, are not distributed evenly throughout the rock. Q: What is the term for a mixture that varies in its composition? Choices: - homogeneous - amorphous - mixed composition - heterogeneous A:
heterogeneous
Q: Answer the following question given this paragraph: Both mitosis and meiosis result in eukaryotic cells dividing. So what is the difference between mitosis and meiosis? The primary difference is the differing goals of each process. The goal of mitosis is to produce two daughter cells that are genetically identical to the parent cell, meaning the new cells have exactly the same DNA as the parent cell. Mitosis happens when you want to grow, for example. You want all your new cells to have the same DNA as the previous cells. The goal of meiosis, however, is to produce sperm or eggs, also known as gametes . The resulting gametes are not genetically identical to the parent cell. Gametes are haploid cells, with only half the DNA present in the diploid parent cell. This is necessary so that when a sperm and an egg combine at fertilization , the resulting zygote has the correct amount of DNAnot twice as much as the parents. The zygote then begins to divide through mitosis. Q: Both mitosis and meiosis result in eukaryotic cells doing what? Choices: - multiplication - friction - limiting - dividing A:
A: dividing
Question: Answer the following question given this paragraph: Sulfur oxides include sulfur dioxide (SO 2 ) and sulfur trioxide (SO 3 ). Sulfur oxides are produced when sulfur and oxygen combine. This happens when coal burns. Coal can contain up to 10 percent sulfur. Q: What is produced when sulfur and oxygen combine? Choices: - treatment oxides - Solid oxides - ethanol oxides - sulfur oxides A:
Answer: sulfur oxides

Answer the following question given this paragraph: Cell division is just one of the stages that a cell goes through during its lifetime. All of the stages that a cell goes through make up the cell cycle . Q: All of the stages that a cell goes through make up what? Choices: - glycolysis - cytokineses - photosynthesis - the cell cycle A:
**Answer**
the cell cycle
