1. Where does fertilization, the fusion of sperm and egg, typically occur in the female reproductive system?

Correct answer: B

Rationale: Fertilization typically occurs in the fallopian tube. After ovulation, the egg is released from the ovary and travels through the fallopian tube, where it may encounter sperm for fertilization. The fallopian tube is the site where the sperm fertilizes the egg before the fertilized egg continues its journey towards the uterus for implantation. The ovary is where the egg is produced but not where fertilization occurs. The uterus is where the fertilized egg implants and develops into a fetus, not where fertilization takes place. The vagina is part of the birth canal and not the typical site for fertilization in the female reproductive system.

2. Why is the lining of the stomach covered with rugae?

Correct answer: B

Rationale: Rugae are folds in the stomach lining that increase its surface area. This increased surface area allows for more efficient digestion and absorption of nutrients in the stomach. Choice A is incorrect because rugae do not directly affect the output of gastric juices. Choice C is incorrect because rugae do not impact the permeability of the stomach walls. Choice D is incorrect because rugae do not influence the types of nutrients that can diffuse.

3. What property of a substance refers to its ability to be drawn into thin wires without breaking?

Correct answer: C

Rationale: Ductility is the property that allows a substance to be drawn into thin wires without breaking. Malleability, on the other hand, is the ability to be hammered or rolled into thin sheets. Viscosity is the measure of a fluid's resistance to flow. Conductivity, lastly, refers to a substance's ability to conduct electricity or heat. Therefore, in this context, the correct answer is ductility as it specifically relates to the ability of a substance to be drawn into thin wires without breaking.

4. What is the path of oxygenated blood flow in our body?

Correct answer: B

Rationale: Oxygenated blood flows from the lungs to the left atrium, then to the left ventricle, and is pumped out through the aorta to the body. This pathway ensures efficient oxygen delivery to the body's tissues and organs. Choice A is incorrect as oxygenated blood does not flow directly from the heart to the brain. Choice C is incorrect as it suggests a route from the body to the right atrium and then to the lungs, which is the pathway for deoxygenated blood. Choice D is incorrect as it describes a direct pathway from the left atrium to the aorta, skipping the left ventricle, which is essential for pumping blood to the body.

5. Which of the following is a unit of measurement for energy?

Correct answer: B

Rationale: The unit of measurement for energy is the Joule (J). Energy is defined as the capacity to do work or produce heat, and the Joule is the standard unit used to measure energy in the International System of Units (SI). A Watt (A) is a unit of power, measured in joules per second, Newton (C) is a unit of force, and Kilogram (D) is a unit of mass. The Joule (J) is the appropriate unit for quantifying energy, making it the correct answer in this context.
