TEAS Test 7 science quizlet Questions

Question 1 of 5

What phenomenon occurs when light passes through a medium without changing direction, such as when passing through a window?

Correct Answer: D

Rationale: The correct answer is 'Transmission.' Transmission refers to the phenomenon where light passes through a medium without changing direction, as observed when light passes through a window. Diffraction involves the bending of light waves around obstacles, reflection is the bouncing back of light waves from a surface, and dispersion is the separation of light into its different colors. In this case, the question specifically asks about the situation where light passes through a medium without changing direction, which aligns with the process of transmission.

Question 2 of 5

How can the peripheral nervous system be further divided?

Correct Answer: A

Rationale: The peripheral nervous system can be further divided into sensory (afferent) neurons that carry information from sensory receptors to the central nervous system and motor (efferent) neurons that carry information from the central nervous system to muscles and glands. Choice A, 'Sensory and motor,' is the correct answer as it accurately identifies the two main functional divisions of the peripheral nervous system. Choices B, 'Sympathetic and parasympathetic,' are divisions of the autonomic nervous system, not the peripheral nervous system. Choice C, 'Myelinated and unmyelinated,' refers to the structural classification of nerve fibers rather than functional divisions. Choice D, 'Central and peripheral,' contrasts the central nervous system with the peripheral nervous system, not further dividing the peripheral nervous system itself.

Question 3 of 5

Rusting of iron is an example of

Correct Answer: A

Rationale: The rusting of iron is an endothermic reaction. This means that it absorbs heat from its surroundings to occur. Rusting involves the slow oxidation of iron in the presence of oxygen and water. As energy is absorbed during this process, it is classified as an endothermic reaction. Choice B, an exothermic reaction, releases heat instead of absorbing it, which is not the case in rusting. Choices C and D are unrelated to the process of rusting and do not involve the absorption of heat from the surroundings.

Question 4 of 5

What pigment is responsible for the yellow color of bananas?

Correct Answer: D

Rationale: Carotene is the pigment responsible for the yellow color of bananas. It belongs to a group of plant pigments called carotenoids, which are responsible for giving fruits and vegetables their vibrant colors, including the yellow hue of bananas. Potassium, calcium, and phosphorus are essential minerals found in bananas but are not responsible for their yellow color.

Question 5 of 5

Which part of the brain is responsible for coordinating muscle movements, maintaining balance, and posture?

Correct Answer: B

Rationale: The correct answer is B, the cerebellum. The cerebellum plays a crucial role in coordinating muscle movements, maintaining balance, and posture. It receives inputs from sensory systems, the spinal cord, and other brain regions to fine-tune motor movements. The cerebrum, choice A, is primarily involved in higher brain functions like thinking and decision-making. The medulla oblongata, choice C, controls essential functions such as breathing and heart rate. The thalamus, choice D, serves as a relay center for sensory information but is not directly responsible for coordinating muscle movements, balance, or posture.
