TEAS version 7 quizlet science

1. Which part of the brain is responsible for regulating heart rate, breathing, and swallowing?

Correct answer: C

Rationale: The correct answer is C, the medulla oblongata. This part of the brain, located at the base of the brainstem, is primarily responsible for regulating essential functions like heart rate, breathing, and swallowing. Choices A, B, and D are incorrect. The cerebrum is associated with higher brain functions such as thinking and voluntary movements, the cerebellum controls coordination and balance, and the thalamus serves as a relay station for sensory information. Therefore, the medulla oblongata specifically governs the autonomic functions critical for survival.

2. Which of these organisms belongs to the kingdom Protista?

Correct answer: C

Rationale: A) Coral belongs to the kingdom Animalia, specifically in the phylum Cnidaria. B) Yeast belongs to the kingdom Fungi. C) Euglena is a unicellular organism that belongs to the kingdom Protista. It is a type of protist that has characteristics of both plants and animals. D) Mushroom belongs to the kingdom Fungi. Therefore, among the options provided, only Euglena belongs to the kingdom Protista.

3. Which type of reaction builds larger and more complex molecules from smaller ones, requiring energy?

Correct answer: B

Rationale: The correct answer is 'Anabolic reaction.' Anabolic reactions involve the synthesis of larger and more complex molecules from smaller ones, requiring an input of energy, often in the form of ATP. These reactions are essential for processes like growth, repair, and the building of cellular structures. Catabolic reactions, on the other hand, break down larger molecules into smaller ones, releasing energy. Exothermic reactions release heat, while hydrolytic reactions involve the breakdown of molecules with the addition of water. Therefore, choices A, C, and D are incorrect as they do not describe the process of building larger and more complex molecules from smaller ones with the requirement of energy.

4. In the body, muscle tissue is involved in which of the following functions?

Correct answer: D

Rationale: Muscle tissue serves multiple functions in the body, including the generation of body heat, joint stabilization, and maintenance of posture. These functions are essential for movement, stability, and overall bodily functions. The correct answer is 'All of the above' because muscle tissue plays a key role in each of these vital functions. The generation of body heat occurs through muscle activity, joint stabilization is achieved by muscles surrounding joints, and maintaining posture involves muscle contraction to support the body's position. Therefore, all the listed functions are interconnected and rely on the proper functioning of muscle tissue.

5. Which term describes the resistance of a substance to being hammered into different shapes?

Correct answer: C

Rationale: Malleability is the property that allows a substance to be hammered or rolled into thin sheets without breaking. It is the opposite of brittleness. Ductility refers to the ability of a material to be drawn into thin wires, not hammered into shapes. Viscosity is the measure of a fluid's resistance to flow, indicating how thick or sticky it is, not related to shaping by hammering. Conductivity refers to the ability of a material to conduct electricity or heat, not resistance to being hammered into different shapes.
