TEAS Test 7 science quizlet

1. 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.

2. Which brain structure is responsible for processing visual information?

Correct answer: B

Rationale: The corrected question and choices are accurate. The correct answer is the Occipital lobe. The occipital lobe, located at the back of the brain, is primarily responsible for processing visual information received from the eyes. It plays a crucial role in interpreting and making sense of visual stimuli, allowing us to perceive and understand the world around us. The other choices, cerebrum (A), frontal lobe (C), and brainstem (D), do not have the primary function of processing visual information. The cerebrum is involved in higher brain functions, the frontal lobe is responsible for decision-making and personality, and the brainstem controls basic life functions like breathing and heart rate.

3. During ejaculation, sperm travels through a tube from the testes to the urethra. What is the name of this tube?

Correct answer: A

Rationale: The vas deferens is the correct answer. It is the tube that carries sperm from the testes to the urethra during ejaculation. The vas deferens plays a crucial role in transporting mature sperm for ejaculation. The epididymis is responsible for sperm maturation and storage, not the direct passage of sperm to the urethra. The seminal vesicle produces fluid that combines with sperm to form semen but is not the tube for sperm transport. The urethra serves as the passageway for both urine and semen out of the body but is not the specific tube that transports sperm from the testes to the urethra.

4. Which organelle is responsible for producing energy in the cell?

Correct answer: B

Rationale: The correct answer is B: Mitochondria. Mitochondria are known as the powerhouse of the cell and are responsible for producing energy in the form of ATP through the process of cellular respiration. The other organelles listed, such as the nucleus, Golgi apparatus, and ribosome, have different functions within the cell and are not directly involved in energy production. The nucleus is responsible for storing genetic material and controlling cell activities. The Golgi apparatus is involved in modifying, sorting, and packaging proteins. Ribosomes are responsible for protein synthesis.

5. What is the primary function of coronary arteries?

Correct answer: B

Rationale: The primary function of coronary arteries is to supply oxygenated blood to the heart muscle itself. The heart is a muscle that needs a constant supply of oxygen and nutrients to function properly. Coronary arteries branch off the aorta and specifically deliver oxygenated blood to the heart muscle, ensuring its proper function. Choice A is incorrect because coronary arteries do not deliver blood throughout the entire body but specifically to the heart. Choice C is incorrect as coronary arteries carry oxygenated blood away from the heart. Choice D is incorrect as the primary function of the coronary arteries is not to regulate blood pressure but rather to provide oxygenated blood to the heart muscle.
