ATI TEAS 7 Science Practice Test Questions
Question 1 of 5
Which of the following is NOT an element of the respiratory system?
Correct Answer: A
Rationale: The correct answer is A: Ribs. The ribs are part of the skeletal system, providing structure and protection to the thoracic cavity. The trachea, diaphragm, and alveoli are all essential components of the respiratory system. The trachea carries air to and from the lungs, the diaphragm aids in breathing by contracting and relaxing to change the volume of the thoracic cavity, and the alveoli are tiny air sacs where gas exchange occurs in the lungs. Therefore, ribs do not play a direct role in the respiratory process and are not considered a part of the respiratory system.
Question 2 of 5
What units of measurement would a triple beam balance show?
Correct Answer: B
Rationale: A triple beam balance is used to measure mass, typically in grams. Liters, meters, and gallons are units of volume, length, and capacity, respectively, not typically measured using a triple beam balance. Therefore, the correct answer is grams. Choice A, Liters, is a unit of volume. Choice C, Meters, is a unit of length. Choice D, Gallons, is a unit of capacity. These units are not typically measured using a triple beam balance.
Question 3 of 5
What function do genes serve in the relationship between parents and offspring?
Correct Answer: A
Rationale: Genes play a crucial role in passing hereditary information from parents to offspring, ensuring the transmission of genetic traits. This process forms the basis of inheritance and genetic continuity between generations. Choice B is incorrect as genes do not prohibit but rather facilitate the transmission of hereditary information. Choice C is incorrect because genes primarily transmit genetic information, while the influence of environmental factors is separate. Choice D is incorrect as genes are fundamental in genetic inheritance and the relationship between parents and offspring.
Question 4 of 5
Which of the following substances is NOT a product of cellular respiration?
Correct Answer: C
Rationale: The correct answer is C. Oxygen is not a product of cellular respiration; instead, it is consumed during the process. During cellular respiration, glucose is broken down in the presence of oxygen to produce energy in the form of ATP, carbon dioxide, and water. Carbon dioxide is released as a waste product, water is a byproduct of the chemical reactions, and ATP is the energy currency used by cells. Therefore, options A, B, and D are all products or outcomes of cellular respiration, while oxygen is a reactant.
Question 5 of 5
Which of the following best describes a plane that divides the body into upper and lower portions?
Correct Answer: B
Rationale: The correct answer is B: Transverse. A transverse plane, also known as a horizontal plane, divides the body into upper and lower portions. This plane is perpendicular to the long axis of the body. Coronal planes divide the body into anterior and posterior portions. Oblique planes pass through the body at an angle, neither strictly horizontal nor vertical. The median plane passes longitudinally through the body, dividing it into equal left and right halves.
