1. Which of the following structures connects muscle to bone?

Correct answer: B

Rationale: Tendons are the correct answer as they are fibrous structures that connect muscle to bone, enabling the transmission of force during movement. Ligaments, on the contrary, connect bone to bone, aiding in joint stability. Muscles contract to generate force and facilitate movement, while bones provide structural support and protect internal organs.

2. Which factor do colligative properties of solutions depend on?

Correct answer: D

Rationale: Colligative properties of solutions depend on the number of solute particles in solution. These properties, such as boiling point elevation, freezing point depression, vapor pressure lowering, and osmotic pressure, are proportional to the number of solute particles present in the solution. The chemical identity of the solute or the concentration of the solvent does not influence colligative properties, making choices A and C incorrect. Therefore, the correct answer is D, the number of solute particles in solution.

3. How does the developing fetus primarily eliminate metabolic wastes?

Correct answer: C

Rationale: Metabolic wastes produced by the developing fetus are eliminated primarily by being passed down the umbilical cord to the mother's circulatory system. Once in the mother's blood, these wastes are then filtered and excreted by the mother's kidneys. Choice A is incorrect because the developing fetus does produce metabolic wastes. Choice B is incorrect as fetal waste does not pass into the mother's anus. Choice D is incorrect as fetal waste does not leave the mother's body via the vagina.

4. Which part of the brainstem is responsible for controlling vital functions such as heart rate, blood pressure, and breathing?

Correct answer: A

Rationale: The medulla oblongata is the correct answer. It is responsible for controlling vital functions such as heart rate, blood pressure, and breathing. This part of the brainstem contains centers that regulate these essential autonomic functions to maintain homeostasis in the body. The pons and midbrain are also parts of the brainstem, but they are not primarily responsible for controlling these vital functions. The cerebellum, on the other hand, is involved in coordination and balance, not in regulating vital functions like heart rate, blood pressure, and breathing.

5. How can a concave mirror be used?

Correct answer: A

Rationale: A concave mirror can be used to focus light to a single point. This property is known as converging light rays to a focal point. When light rays parallel to the principal axis strike a concave mirror, they converge at a specific point called the focal point. This ability to focus light makes concave mirrors useful in applications such as reflecting telescopes and shaving mirrors. Choice B is incorrect because concave mirrors can create both real and virtual images, depending on the object's position relative to the mirror. Choice C is incorrect as concave mirrors can magnify, reduce, or maintain the size of objects, depending on the object's position and the distance from the mirror. Choice D is incorrect as concave mirrors do not scatter light but instead have the ability to reflect and focus light to produce clear images.
