Q: The pituitary gland is called the "master gland" of what system? Read this paragraph and choose the correct option from the provided answers: The pea-sized pituitary gland is just below the hypothalamus and attached directly to it. The pituitary receives hormones from the hypothalamus. It also secretes its own hormones. Most pituitary hormones control other endocrine glands. That's why the pituitary gland is called the "master gland" of the endocrine system. Table below lists several pituitary hormones and what they do. Choices: - hormonal - digestive - nervous - endocrine A:
**Answer**
endocrine

Q: Microwaves are converted into what kind of energy in a microwave oven? Read this paragraph and choose the correct option from the provided answers: Electromagnetic waves may also be absorbed by matter and converted to other forms of energy. Microwaves are a familiar example. When microwaves strike food in a microwave oven, they are absorbed and converted to thermal energy, which heats the food. Choices: - solar energy - mechanical energy - light energy - thermal energy A:
**Answer**
thermal energy

Q: An electrical motor changes electrical energy into what? Read this paragraph and choose the correct option from the provided answers: Electrical motors change electrical energy into mechanical energy. The motor consists of an electrical circuit with part of the wires inside a magnetic field. This can be seen below. Positive charges move through the circuit in the direction of the light purple arrows. When the charges move up through the part of the coil that is right next to the north pole, the right hand rule tells us that the wire suffers the force, F , pushing the wire in the direction of the blue arrow, toward the back of the sketch. On the other side of the coil, where the charges are moving down through the field, the right hand rule shows the force would push this side of the coil toward the front. These two forces are working together, rotating the coil in the direction of the circular red arrow. Choices: - chemical energy - solar energy - thermal energy - mechanical energy A:
**Answer**
mechanical energy
