TEAS 7 science practice questions

1. What type of energy does a stretched rubber band possess?

Correct answer: B

Rationale: When a rubber band is stretched, it stores potential energy due to its position or configuration. This potential energy can be converted into kinetic energy when the rubber band is released and returns to its original shape. Therefore, the correct answer is potential energy, as the energy is stored in the stretched rubber band and can be released upon returning to its original state. Choices A, C, and D are incorrect because kinetic energy is associated with motion, thermal energy is related to heat, and mechanical energy is a broader category that includes both potential and kinetic energy.

2. Which respiratory structure is responsible for vocalization and sound production?

Correct answer: B

Rationale: The correct answer is B: Larynx. The larynx, also known as the voice box, is the respiratory structure responsible for vocalization and sound production. It contains the vocal cords, which vibrate as air passes through, producing sound. The trachea (A) connects the larynx to the bronchi. While the trachea serves as the windpipe, it is not directly involved in sound production. Bronchi (C) are airway passages that branch off from the trachea and lead to the lungs, but they are not responsible for vocalization. Alveoli (D) are tiny air sacs in the lungs where gas exchange occurs, but they are not involved in sound production.

3. What are the phases of bacterial growth and infection?

Correct answer: A

Rationale: The correct answer is A: Lag, exponential, stationary, death. The phases of bacterial growth start with the lag phase where bacteria acclimate to their environment, followed by the exponential phase characterized by rapid growth. This is then followed by the stationary phase where growth slows as resources deplete, and finally, the death phase where the population declines. Choice B is incorrect as it has the order of phases mixed up. Choice C is incorrect as it also has the order of phases mixed up. Choice D is incorrect as it has the stationary phase occurring before the exponential phase, which is inaccurate.

4. What is the term for the division of the cytoplasm?

Correct answer: A

Rationale: Cytokinesis is the correct term for the division of the cytoplasm during cell division. It is the final stage of cell division, following either mitosis or meiosis, where the cytoplasm of a parent cell is divided into two daughter cells. Mitosis is the process of nuclear division, while meiosis is a type of cell division that results in four daughter cells with half the number of chromosomes of the parent cell. Apoptosis, on the other hand, is programmed cell death and not the division of the cytoplasm.

5. What is the process by which the body reabsorbs water from the large intestine?

Correct answer: B

Rationale: Osmosis (Option B) is the correct process by which the body reabsorbs water from the large intestine. Osmosis is the movement of water across a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration. In the large intestine, water is reabsorbed through osmosis to maintain the body's fluid balance. Dehydration (Option A) refers to the condition of having insufficient water in the body, not the process of water reabsorption in the large intestine. Filtration (Option C) is a process where a liquid or gas passes through a filter to separate the components, not the primary mechanism for water reabsorption in the large intestine. Secretion (Option D) is the release of substances from cells, but it is not the process by which the body reabsorbs water from the large intestine.
