Ques:Q: What term describes waves that travel through matter? Read this paragraph and choose the correct option from the provided answers: Waves that travel through mattersuch as the fabric of a flagare called mechanical waves. The matter they travel through is called the medium. When the energy of a wave passes through the medium, particles of the medium move. The more energy the wave has, the farther the particles of the medium move. The distance the particles move is measured by the wave's amplitude. Choices: - replaced waves - water waves - heat waves - mechanical waves A:

Ans:mechanical waves

Ques:Q: What specific part of the brain regulates the endocrine system? Read this paragraph and choose the correct option from the provided answers: The endocrine system consists of glands that secrete hormones into the bloodstream. It is regulated by a part of the brain called the hypothalamus, which also secretes hormones. The hypothalamus controls the pituitary gland, which is called the "master gland" of the endocrine system because its hormones regulate other endocrine glands. Other endocrine glands include the thyroid gland and pancreas. Choices: - parietal lobe - hippocampus - frontal lobe - hypothalamus A:

Ans:hypothalamus

Ques:Q: What kind of energy comes from the position of a charged particle in an electric field? Read this paragraph and choose the correct option from the provided answers: Electric potential energy comes from the position of a charged particle in an electric field. For example, when two negative charges are close together, they have potential energy because they repel each other and have the potential to push apart. If the charges actually move apart, their potential energy decreases. Electric charges always move spontaneously from a position where they have higher potential energy to a position where they have lower potential energy. This is like water falling over a dam from an area of higher to lower potential energy due to gravity. Choices: - solar energy - mechanical energy - thermal energy - potential energy A:

Ans:
potential energy
