1. What force causes an object to move in a circular path?

Correct answer: C

Rationale: The centripetal force is the force responsible for keeping an object moving in a circular path. It is directed towards the center of the circle, providing the necessary inward acceleration to maintain the object's curved trajectory. Without this force, the object would move in a straight line tangent to the circle. Tension force, frictional force, and gravitational force are not the forces that cause an object to move in a circular path. Tension force is typically present in a string or rope and acts along the length of the material. Frictional force opposes the motion of an object relative to a surface, and gravitational force is the force of attraction between two masses.

2. Bile, a digestive juice, is produced by which organ?

Correct answer: B

Rationale: Bile is a digestive juice produced by the liver. It is stored in the gallbladder and released into the small intestine to aid in the digestion and absorption of fats. The stomach (Choice A) produces gastric juices, not bile. The pancreas (Choice C) produces digestive enzymes and bicarbonate but not bile. The small intestine (Choice D) is where bile is released to aid in digestion but is not the organ that produces bile.

3. What is the primary function of the large intestine?

Correct answer: C

Rationale: The large intestine's primary function is to absorb water from undigested food remnants and compact them into solid waste (feces). This process helps regulate hydration levels in the body and aids in waste elimination. Choices A, B, and D are incorrect. Absorbing digested material into the blood is mainly done in the small intestine, nutrient processing and metabolizing occur in various parts of the digestive system, and bile production and storage are functions of the liver and gallbladder, not the large intestine.

4. If an atom has 32 neutrons, 17 protons, and 19 electrons, what is its charge?

Correct answer: A

Rationale: An atom's charge is determined by the difference between the number of protons and electrons. Since the atom has 17 protons and 19 electrons, the net charge is positive. The excess of two electrons compared to protons results in a positive charge. Choice B (Negative) is incorrect because the atom has more protons than electrons, leading to a positive charge. Choice C (Neutral) is incorrect because the atom has an imbalance between protons and electrons, resulting in a charge. Choice D (Cannot be determined) is incorrect as the charge can be determined based on the given information.

5. What is the primary function of the ovaries in the female reproductive system?

Correct answer: C

Rationale: The primary function of the ovaries in the female reproductive system is to produce eggs (ova). Ovaries are responsible for the production of female gametes. Additionally, they secrete hormones such as estrogen and progesterone, which are essential for the menstrual cycle and pregnancy. Transporting sperm to the uterus is the function of the fallopian tubes, not the ovaries. Producing milk for feeding offspring is the role of the mammary glands, not the ovaries. Regulating urination is a function associated with the urinary system, not the female reproductive system or the ovaries.
