TEAS 7 science practice questions

1. What is the scientific term for scar tissue?

Correct answer: B

Rationale: The correct scientific term for scar tissue is fibrous connective tissue. Scar tissue is primarily composed of fibrous connective tissue, which forms as part of the body's natural healing process in response to injury or trauma. Epithelial tissue, cartilage, and adipose tissue are not typically involved in scar formation. Therefore, the correct answer is fibrous connective tissue, as it is the specific type of tissue that makes up scar tissue.

2. What is the definition of power in physics?

Correct answer: B

Rationale: The correct answer is B: 'The rate of doing work or transferring energy.' Power in physics is defined as the rate at which work is done or energy is transferred. It is a measure of how quickly energy is transferred or converted. Power is not the same as energy itself but rather how fast energy is being transferred or converted. Choice A, 'The rate of change of energy,' is incorrect because power is about the rate of work or energy transfer, not just the change in energy. Choice C, 'The measure of an object's potential energy,' is incorrect as power is not a measure of potential energy but rather the rate of energy transfer. Choice D, 'The force exerted on an object,' is incorrect as power is related to work and energy transfer, not just force exerted.

3. What lab equipment would most likely be used to precisely measure the volume of a liquid solution?

Correct answer: C

Rationale: A graduated cylinder is the most suitable lab equipment for precisely measuring the volume of a liquid solution. Graduated cylinders are designed with calibrated markings that allow for accurate volume measurements of liquids. The other choices are not appropriate for measuring liquid volume: Flasks are used for mixing or storing liquids, triple beam balances are used for measuring mass, and test tubes are typically used for holding small amounts of substances during experiments.

4. Which part of the ear is responsible for transmitting sound vibrations to the inner ear?

Correct answer: B

Rationale: The correct answer is B: Ossicles. The ossicles, consisting of the malleus, incus, and stapes, are located in the middle ear. They play a crucial role in transmitting sound vibrations from the eardrum to the inner ear, specifically to the cochlea. The cochlea is responsible for converting sound vibrations into electrical signals for the brain to interpret. The semicircular canals are not involved in transmitting sound but are responsible for balance and orientation. The eustachian tube's function is to help equalize pressure in the middle ear, not to transmit sound vibrations.

5. Which type of energy is possessed by an object due to its position or configuration?

Correct answer: C

Rationale: Potential energy is the energy that an object possesses due to its position or configuration. It is considered stored energy that can be converted into other forms of energy to do work. When an object is lifted against gravity or compressed, it gains potential energy. Kinetic energy, the incorrect choice A, is the energy of motion possessed by an object. Thermal energy, the incorrect choice B, is related to the temperature of an object due to the motion of its particles. Electrical energy, the incorrect choice D, is related to the flow of electric charge in a circuit or system. Therefore, the correct answer is potential energy as it is associated with an object's position or configuration.
