Correct Answer: B

Rationale: The retina is the correct answer as it is the light-sensitive structure in the eye that detects light and converts it into signals for the brain to process visual information. The cornea is the transparent outer covering of the eye that helps to focus incoming light onto the lens. The lens further focuses the light onto the retina, which is where the actual light detection and signal conversion occur. The iris, on the other hand, controls the amount of light entering the eye by adjusting the size of the pupil but is not directly responsible for detecting light.

Correct Answer: A

Rationale: The pleurae play a crucial role in compartmentalizing and lubricating the lungs. The pleura is a double-layered membrane that surrounds the lungs and lines the chest cavity. This double-layered structure reduces friction between the lungs and the chest wall during breathing movements, allowing smooth expansion and contraction of the lungs. Options B, C, and D are incorrect. Option B, '
To facilitate the flow of air,' is incorrect because while the pleurae are involved in the respiratory process, their primary function is not to directly facilitate the flow of air. Option C, '
To produce mucus,' is incorrect as the production of mucus is not a primary function of the pleurae. Option D, '
To serve as the passageway for air,' is incorrect as the passageway for air refers to the air passages like the trachea and bronchi, not the pleurae.
Therefore, option A is correct as it accurately describes the function of the pleurae.

Correct Answer: C

Rationale: The correct answer is C: Renal vessel damage. High blood pressure can lead to damage in blood vessels throughout the body, including the kidneys. When blood vessels in the kidneys are affected, it can impair kidney function and potentially lead to kidney disease. Smoking (
Choice
A) and excessive dietary salt (
Choice
B) can contribute to high blood pressure but are not direct effects of high blood pressure itself. Older age (
Choice
D) is a risk factor for developing high blood pressure but is not a direct effect of high blood pressure.

Correct Answer: A

Rationale:
Choice A is the best example of a hypothesis as it presents a testable statement regarding the impact of environmental temperature on plant root growth. A hypothesis should be specific and capable of being tested through experimentation, which is demonstrated in choice A.
Choice B is a general statement rather than a testable hypothesis.
Choice C lacks specificity and does not clearly state a cause-and-effect relationship to be tested.
Choice D provides a specific time frame but does not address a relationship that can be tested through experimentation, making it less suitable as a hypothesis compared to choice A.

Correct Answer: D

Rationale: The correct answer is D: Villi. Villi are small, finger-like projections in the small intestine that increase the surface area for absorption, aiding in the absorption of nutrients. Cilia (
Choice
A) are tiny hair-like structures found in various parts of the body but are not present in the small intestine. Rugae (
Choice
B) are folds in the mucosa of the stomach that allow for its expansion during digestion. The trachea (
Choice
C) is part of the respiratory system, responsible for carrying air to and from the lungs, and is not related to the small intestine.
