ATI TEAS 7

Practice TEAS Science Test

1. How many molecules of NADPH and ATP are required to reduce 6 molecules of CO2 to glucose via photosynthesis?

A. 6 NADPH and 9 ATP
B. 12 NADPH and 18 ATP
C. 18 NADPH and 24 ATP
D. 24 NADPH and 36 ATP

Correct answer: B

Rationale: During photosynthesis, 12 molecules of NADPH and 18 molecules of ATP are required to reduce 6 molecules of CO2 to glucose. NADPH and ATP are essential energy carriers in the process of photosynthesis. Choice A is incorrect because it underestimates the required molecules of both NADPH and ATP. Choices C and D overestimate the number of molecules needed, making them incorrect answers.

2. What are the three regions of the small intestine?

A. Duodenum, ileum, jejunum
B. Cecum, ileum, jejunum
C. Duodenum, jejunum, ileum
D. Duodenum, jejunum, colon

Correct answer: C

Rationale: The correct answer is C: Duodenum, jejunum, ileum. The small intestine is divided into three regions: the duodenum, jejunum, and ileum. The duodenum is the initial segment where most chemical digestion takes place. The jejunum and ileum follow the duodenum and are primarily responsible for nutrient absorption. Choice A is incorrect because the order is incorrect. Choice B is incorrect because the cecum is part of the large intestine, not the small intestine. Choice D is incorrect because the colon is part of the large intestine, not the small intestine.

3. What is the process of cells restoring damaged or lost tissues called?

A. Cell division
B. Cell differentiation
C. Cell growth
D. Cell regeneration

Correct answer: D

Rationale: Rationale: A) Cell division refers to the process by which a cell divides into two daughter cells. B) Cell differentiation is the process by which cells become specialized for specific functions. C) Cell growth is the increase in cell size or number. D) Cell regeneration is the process of cells restoring damaged or lost tissues by replacing or repairing the damaged cells. This process is essential for healing wounds and maintaining tissue integrity.

4. When a patient is lying flat on their back, which of the following positions are they in?

A. Prone.
B. Supine.
C. Lateral.
D. Medial.

Correct answer: B

Rationale: When a patient is lying flat on their back, they are in the supine position. In the supine position, the person's face is facing upward, and their back is touching the surface they are lying on. This position is commonly used for medical examinations and procedures. Choice A, 'Prone,' refers to lying face down, not on the back. Choice C, 'Lateral,' indicates lying on the side. Choice D, 'Medial,' pertains to the middle or center, not a position in relation to lying on the back.

5. Which property of matter measures the amount of space occupied by an object?

A. Mass
B. Density
C. Weight
D. Volume

Correct answer: D

Rationale: Volume is the property of matter that measures the amount of space occupied by an object. Mass refers to the amount of matter in an object, weight is the force of gravity acting on an object, and density is the mass of an object per unit volume. Volume specifically quantifies the space occupied by an object, making it the correct answer in this context.
