Correct Answer: C

Rationale: The correct answer is C: Retina. Visual processing begins in the retina because it contains specialized cells called photoreceptors (rods and cones) that convert light into electrical signals. These signals are then transmitted through the optic nerve to the brain for further processing. The cornea (A) is the transparent outer layer of the eye that helps focus light, the optic nerve (B) transmits signals from the retina to the brain, and the eyelid (D) is a protective covering for the eye and does not play a role in visual processing.

Correct Answer: A

Rationale: The correct order for increasing amounts of permitted motion is hinge joint (least mobile), condyloid joint, and saddle joint (most mobile). A: Hinge joint allows movement in one plane (least mobile), followed by condyloid joint with two planes, and then saddle joint with more freedom of movement. B: Incorrect order as saddle joint is more mobile than hinge joint. C: Incorrect order as hinge joint should be first, followed by condyloid and then saddle joint. D: Incorrect order as saddle joint should be the most mobile joint in the list.

Correct Answer: A

Rationale: The correct answer is A: They're both accurate and precise. Rationale: 1. Accuracy: The measurements are close to the accepted value of 9.8 m/s^2, with a range of 9.78-9.81 m/s^2. 2. Precision: The measurements are consistent and clustered closely around the true value, indicating precision. 3. The slight variations in measurements are expected due to experimental error but still fall within an acceptable range. In summary, the measurements are accurate as they are close to the true value, and they are precise as they are clustered closely together. Other choices are incorrect because they do not accurately reflect the situation based on the provided data.

Correct Answer: B

Rationale: The correct answer is B (50%). When an A heterozygote (IAi) individual and an O (ii) individual have a child, the possible genotypes of the offspring are IAi (A blood type) and ii (O blood type). Since A and O blood types are determined by codominant and recessive alleles respectively, the child has a 50% chance of inheriting the A allele from the A heterozygote parent, resulting in A blood type. Therefore, the probability of the child having A blood type is 50%. Choice A (25%) is incorrect because it does not consider the possibility of the child inheriting the A allele from the A heterozygote parent. Choice C (75%) and choice D (100%) are incorrect as they overestimate the probability by not accounting for the presence of the O allele in the O parent, which would result in the child having O blood type.

Correct Answer: D

Rationale: The correct answer is D: Arteries. Arteries carry oxygen-rich blood away from the heart to the body tissues. They have thick, muscular walls to withstand the high pressure of blood pumped from the heart. Veins (A) carry oxygen-poor blood back to the heart. Intestines (B) are part of the digestive system, and bronchioles (C) are small air passages in the lungs.
