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:
(Answer)
tough cuticle covering
Ques: Answer the following question given this paragraph: Molecular geometry is the three-dimensional arrangement of atoms in a molecule. The molecular geometry, or shape, of a molecule is an important factor that affects the physical and chemical properties of a compound. Those properties include melting and boiling points, solubility, density, and the types of chemical reactions that a compound undergoes. In this lesson, you will learn a technique to predict molecular geometry based on a molecule's Lewis electron dot structure. Q: Molecular geometry is the three-dimensional arrangement of atoms in a what? Choices: - genes - DNA - nucleus - molecule A:
Ans: molecule
(Q).
Answer the following question given this paragraph: Fossil fuels provide most of the energy used worldwide. Richer nations use far more energy resources, especially fossil fuels, than poorer nations do. There are several ways that people can conserve energy in their daily lives. Q: What fuels provide most of the energy used worldwide? Choices: - hydroelectric - solar - renewable - fossil A:
(A).
fossil
Ques:Answer the following question given this paragraph: The second equation is equivalent to the first. Voltage is not the same as energy. Voltage is the energy per unit charge. Thus a motorcycle battery and a car battery can both have the same voltage (more precisely, the same potential difference between battery terminals), yet one stores much more energy than the other since PE = qV . The car battery can move more charge than the motorcycle battery, although both are 12 V batteries. Q: What term is not the same as energy, but means the energy per unit charge? Choices: - frequency - speed - mass - voltage A:

Ans:voltage
Question: Answer the following question given this paragraph: Nutrients can enter or exit an ecosystem at any point and can cycle around the planet. Q: At what point can nutrients enter or exit an ecosystem? Choices: - Largest Population Point - Longest Point - Hottest Point - any point A:
Answer:
any point
