1. Which organ is primarily responsible for detoxification in the body?

Correct answer: B

Rationale: The liver is the primary organ responsible for detoxifying chemicals and metabolizing drugs in the body. It plays a crucial role in breaking down toxins, filtering blood, and producing bile, making it essential for overall detoxification processes. The kidney primarily filters waste and excess substances from the blood to form urine. Lungs are responsible for gas exchange, not detoxification. The heart is responsible for pumping blood and does not play a direct role in detoxification processes.

2. Which part of the brain is responsible for higher brain functions, such as thought and action?

Correct answer: D

Rationale: The cerebrum is the correct answer as it is responsible for higher brain functions like thought and action. The amygdala (Choice A) is involved in emotions and emotional responses, not higher brain functions. The brain stem (Choice B) controls basic life functions such as breathing and heart rate, not higher brain functions. The cerebellum (Choice C) is mainly responsible for motor control and coordination, not higher brain functions like thought and action.

3. What is the primary function of the strong nuclear force?

Correct answer: B

Rationale: The strong nuclear force primarily functions to bind protons and neutrons within the nucleus. It is responsible for overcoming the electrostatic repulsion between positively charged protons, holding the nucleus together. Choices A, C, and D are incorrect because the strong nuclear force specifically acts on nucleons (protons and neutrons) within the nucleus, not on electrons in atomic orbitals or charges outside the nucleus.

4. Which type of energy is associated with the random motion of particles in a substance?

Correct answer: C

Rationale: Thermal energy is the correct answer as it is associated with the random motion of particles in a substance. When particles move randomly, they generate heat energy, which is a form of thermal energy. Potential energy is stored energy that can be converted into other forms when released, such as kinetic energy. Mechanical energy is the sum of potential and kinetic energy in an object, which is not directly related to the random motion of particles. Chemical energy is energy stored in the bonds of chemical compounds and is not specifically related to the motion of particles.

5. Which hormone deficiency can lead to stunted growth and developmental delays in children?

Correct answer: C

Rationale: The correct answer is C, Growth hormone. Growth hormone plays a crucial role in stimulating growth, cell reproduction, and regeneration in children. A deficiency in growth hormone can lead to stunted growth and developmental delays. Estrogen and testosterone are sex hormones that do not directly influence growth in the same way as growth hormone. Insulin primarily regulates blood sugar levels and is not the primary hormone responsible for growth and development in children.
