Answer the following question given this paragraph: In benzene, the true bonding between carbon atoms is neither a single nor a double bond. Rather, all of the bonds are a hybrid of a single and double bond. In benzene, the pi bonding electrons are free to move completely around the ring. Delocalized electrons are electrons that are not confined to the bond between two atoms, but are instead allowed to move between three or more. The delocalization of the electrons in benzene can best be shown by showing benzene with a ring inside the hexagon, with the hydrogen atoms understood. Q: What type of electrons are electrons that are not confined to the bond between two atoms? Choices: - virtualized - detached - internalized - delocalized A:
delocalized

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
