1. Abduction is defined as which of the following?

• A. Movement away from the midline of the body
• B. Movement that results in a decrease in the angle of a joint
• C. Movement that results in an increase in the angle of a joint
• D. Movement towards the midline of the body

Correct answer: A

Rationale: Abduction is defined as movement away from the midline of the body. This movement occurs in the coronal plane and is essential in various body functions such as raising the arms sideways. Choices B, C, and D describe movements that are different from abduction. Choice B refers to flexion, which decreases the angle of a joint. Choice C describes extension, which increases the angle of a joint. Choice D defines adduction, which involves movement towards the midline of the body. Therefore, the correct answer is choice A.

2. What lab equipment would most likely be used to precisely measure the volume of a liquid solution?

• A. Flask
• B. Triple beam balance
• C. Graduated cylinder
• D. Test tube

Correct answer: C

Rationale: A graduated cylinder is the most suitable lab equipment for precisely measuring the volume of a liquid solution. Graduated cylinders are designed with calibrated markings that allow for accurate volume measurements of liquids. The other choices are not appropriate for measuring liquid volume: Flasks are used for mixing or storing liquids, triple beam balances are used for measuring mass, and test tubes are typically used for holding small amounts of substances during experiments.

3. Rusting of iron is an example of

• A. Endothermic reaction
• B. Exothermic reaction
• C. Single displacement reaction
• D. Photochemical reaction

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.

4. Which of the following is a pair of nerves that originates from the brain?

• A. Spinal nerves
• B. Olfactory nerves
• C. Sciatic nerve
• D. Optic nerve

Correct answer: B

Rationale: The olfactory nerves, choice B, are a pair of cranial nerves that originate from the brain. They are responsible for the sense of smell and are the only cranial nerves that directly connect to the cerebrum. Spinal nerves, choice A, originate from the spinal cord, the sciatic nerve, choice C, is a large nerve that originates in the lower back, and the optic nerve, choice D, originates from the retina of the eye. Therefore, choices A, C, and D are incorrect as they do not originate directly from the brain.

5. Which of the following organs does not belong with the others?

• A. Thyroid gland
• B. Stomach
• C. Intestines
• D. Pancreas

Correct answer: B

Rationale: The correct answer is B - Stomach. The stomach is primarily involved in the digestive system, breaking down food through digestion. In contrast, the thyroid gland, intestines, and pancreas are part of the endocrine system or digestive system, involved in hormone production, nutrient absorption, and digestion. Therefore, the stomach stands out as the odd one in this group as it is the only organ specifically dedicated to digestion, while the others have dual roles or different primary functions.
