Q: What do dendrites receive signals from? Read this paragraph and choose the correct option from the provided answers: Choices: - hormones - fibers - electrons - neurons A:
neurons

Q: Glycolysis, the krebs cycle, and the electron transport chain are stages in what process? Read this paragraph and choose the correct option from the provided answers: The many steps in the process of aerobic cellular respiration can be divided into three stages. The first stage, glycolysis, produces ATP without oxygen. Because this part of the cellular respiration pathway is universal, biologists consider it the oldest segment. Note that glycogen and fats can also enter the glycolysis pathway. The second stage is the Krebs Cycle, and the third stage is the electron transport chain. It is during the third stage that chemiosmosis produces numerous ATP molecules. Choices: - cell death - reproduction - mitosis - aerobic cellular respiration A:
aerobic cellular respiration

Q: What is the process of breaking down food into components the body can absorb called? Read this paragraph and choose the correct option from the provided answers: The digestive system has three main functions: digestion of food, absorption of nutrients, and elimination of solid food waste. Digestion is the process of breaking down food into components the body can absorb. It consists of two types of processes: mechanical digestion and chemical digestion. Choices: - absorption - filtration - excretion - digestion A:
digestion

Q: Magnetism is due to the movement of what within atoms? Read this paragraph and choose the correct option from the provided answers: Magnetism is due to the movement of electrons within atoms of matter. When electrons spin around the nucleus of an atom, it causes the atom to become a tiny magnet, with north and south poles and a magnetic field. In most materials, the electrons orbiting the nuclei of the atoms are arranged in such a way that the materials have no magnetic properties. Also, in most types of matter, the north and south poles of atoms point in all different directions, so overall the matter is not magnetic. Examples of nonmagnetic materials include wood, glass, plastic, paper, copper, and aluminum. These materials are not attracted to magnets and cannot become magnets. Choices: - neutrons - protons - magnetrons - electrons A:
electrons
