TEAS version 7 quizlet science
1. Which property of a substance refers to its ability to be stretched into thin wires without breaking?
- A. Conductivity
- B. Viscosity
- C. Ductility
- D. Malleability
Correct answer: C
Rationale: Ductility is the property of a substance that allows it to be stretched into thin wires without breaking. This property is distinct from the other options provided. Conductivity refers to the ability to conduct electricity or heat, viscosity refers to a liquid's resistance to flow, and malleability refers to the ability of a substance to be hammered or rolled into thin sheets. Therefore, the correct answer is 'Ductility.'
2. What is the law of conservation of energy?
- A. Energy cannot be created, only destroyed
- B. Energy can be created but not destroyed
- C. Energy can neither be created nor destroyed, only transformed from one form to another
- D. Energy is always created in any process
Correct answer: C
Rationale: The correct answer is C: 'Energy can neither be created nor destroyed, only transformed from one form to another.' The law of conservation of energy is a fundamental principle in physics. It states that the total energy in a closed system remains constant over time. Energy can change from one form to another (e.g., potential energy to kinetic energy), but the total amount of energy remains the same. Choices A, B, and D are incorrect because they do not accurately represent the law of conservation of energy. Energy is not created or destroyed according to this law, but rather transformed.
3. Which of the following joints allows for side-to-side bending movements?
- A. Hinge joint
- B. Ball-and-socket joint
- C. Gliding joint
- D. Saddle joint
Correct answer: C
Rationale: The correct answer is C, Gliding joint. Gliding joints allow for side-to-side bending movements. These joints are found between the small bones of the wrist and ankle, allowing for flexibility and movement in multiple directions. Hinge joints (A) enable movement in one plane, akin to a door hinge. Ball-and-socket joints (B) allow for a wide range of motion across multiple directions. Saddle joints (D) facilitate movement in two planes.
4. What are the seven components of the digestive system?
- A. Mouth, esophagus, stomach, small intestine, large intestine, liver, pancreas
- B. Mouth, pharynx, esophagus, stomach, small intestine, large intestine, rectum
- C. Esophagus, stomach, liver, pancreas, small intestine, large intestine, rectum
- D. Pharynx, stomach, liver, pancreas, small intestine, large intestine, rectum
Correct answer: B
Rationale: The correct answer is B. The seven components of the digestive system are the mouth, pharynx, esophagus, stomach, small intestine, large intestine, and rectum. The mouth begins the process of digestion by chewing and mixing food with saliva. The pharynx serves as a passageway for food and air. The esophagus transports food from the mouth to the stomach. The stomach aids in digestion and acts as a temporary storage site. The small intestine is where most of the digestion and absorption of nutrients occur. The large intestine absorbs water and salts, forming feces. The rectum stores feces until they are eliminated through the anus. The other choices are incorrect as they do not list all seven essential components of the digestive system.
5. Which property of matter refers to the measure of the force of gravity acting on an object?
- A. Mass
- B. Weight
- C. Density
- D. Volume
Correct answer: B
Rationale: The correct answer is 'Weight.' Weight is the measure of the force of gravity acting on an object. Mass refers to the amount of matter in an object, density is the mass per unit volume of a substance, and volume is the amount of space an object occupies. In this context, the question specifically asks for the property related to the force of gravity, making 'Weight' the correct choice. 'Mass' is the measure of the amount of matter in an object, 'Density' is the mass per unit volume of a substance, and 'Volume' is the space occupied by an object, none of which directly measure the force of gravity on an object.
