Ques: Answer the following question given this paragraph: Forms of Energy The forms of energy include thermal energy, radiant energy, electrical energy, nuclear energy, and chemical energy (Figure 5.1 "Forms of Energy"). Thermal energy results from atomic and molecular motion; the faster the motion, the greater the thermal energy. The temperature of an object is a measure of its thermal energy content. Radiant energy is the energy carried by light, microwaves, and radio waves. Objects left in bright sunshine or exposed to microwaves become warm because much of the radiant energy they absorb is converted to thermal energy. Electrical energy results from the flow of electrically charged particles. When the ground and a cloud develop a separation of charge, for example, the resulting flow of electrons from one to the other produces lightning, a natural form of electrical energy. Nuclear energy is stored in the nucleus of an atom, and chemical energy is stored within a chemical compound because of a particular arrangement of atoms. (a) Thermal energy results from atomic and molecular motion; molten steel at 2000C has a very high thermal energy content. (b) Radiant energy (e. , from the sun) is the energy in light, microwaves, and radio waves. (c) Lightning is an example of electrical energy, which is due to the flow of electrically charged particles. (d)Nuclear. Q: The temperature of an object is a measure of what type of energy? Choices: - chemical - magnetic - density - thermal A:
Ans: thermal

Ques: Answer the following question given this paragraph: described in the chapter on muscle tissue, an action potential travels along the motor neuron axon into the periphery. The axon terminates on muscle fibers at the neuromuscular junction. Acetylcholine is released at this specialized synapse, which causes the muscle action potential to begin, following a large potential known as an end plate potential. When the lower motor neuron excites the muscle fiber, it contracts. All of this occurs in a fraction of a second, but this story is the basis of how the nervous system functions.

Ques: Answer the following question given this paragraph: Did you ever see workers sandblasting a building to clean it? Sand is blown onto the surface to scour away dirt and debris. Wind-blown sand has the same effect. It scours and polishes rocks and other surfaces. Wind-blown sand may carve rocks into interesting shapes. You can see an example in Figure below . This form of erosion is called abrasion. It occurs any time rough sediments are blown or dragged over surfaces. Can you think of other ways abrasion might occur?. Q: Wind blown sand contributes to what type of erosion? Choices: - vegetation - sedimentary - filtration - abrasion A:
Ans: abrasion

Ques: Answer the following question given this paragraph: Muscle tissue is made up of bands of cells that contract and allow movement. Q: What is made up of bands of cells that contract for movement? Choices: - vascular tissue - collagen - cartilage - muscle tissue A:
Ans:
muscle tissue
