ATI TEAS 7 Science Practice Test Questions
Question 1 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 2 of 5
Which of the following is an example of the location and function of cartilage in the body?
Correct Answer: B
Rationale: Cartilage is a type of flexible connective tissue that acts as supportive pads providing cushioning at joints, like those found between the vertebrae of the spine. This specific function of cartilage helps in reducing friction and absorbing shock in these areas, contributing to joint flexibility and protection. Choices A, C, and D do not accurately describe the function and location of cartilage in the body. Option A incorrectly refers to dense connective tissue, which is different from cartilage. Option C describes tendons or ligaments, which are not cartilage. Option D refers to adipose tissue, which is a type of connective tissue that stores fat and provides insulation, but it is not cartilage.
Question 3 of 5
What is the process of changing from a liquid to a gas called?
Correct Answer: C
Rationale: The correct answer is C: Vaporization. Vaporization is the process by which a substance changes from a liquid state to a gas state. Choice A, Freezing, is incorrect as it refers to the process of changing from a liquid to a solid. Choice B, Condensation, is incorrect as it describes the process of changing from a gas to a liquid. Choice D, Sublimation, is incorrect as it involves changing directly from a solid to a gas without passing through the liquid state.
Question 4 of 5
Which structure controls the hormones secreted by the pituitary gland?
Correct Answer: A
Rationale: The correct answer is A: Hypothalamus. The hypothalamus controls the release of hormones from the pituitary gland. It acts as a master regulator of the endocrine system by producing releasing and inhibiting hormones that influence the secretion of hormones from the pituitary gland. Choice B, the Adrenal gland, is incorrect because while it plays a role in hormone production, it is not responsible for controlling the pituitary gland's hormones. Choice C, the Testes, and Choice D, the Pancreas, are also incorrect as they are not directly involved in controlling the hormones secreted by the pituitary gland.
Question 5 of 5
Two isotopes of the same element have different numbers of:
Correct Answer: C
Rationale: The correct answer is C: 'Neutrons.' Isotopes are variants of an element that have the same number of protons and electrons but differ in the number of neutrons they contain. This difference in neutron count is what distinguishes isotopes from each other while maintaining the same chemical properties. Choice A, 'Electrons,' is incorrect because isotopes of the same element have the same number of electrons. Choice B, 'Protons,' is incorrect because isotopes of the same element have the same number of protons. Choice D, 'Nuclei,' is incorrect as nuclei refer to the central part of an atom containing protons and neutrons, and the question specifically asks about differences between isotopes of the same element.
