Biology

1. Which of the following is the main organ responsible for absorbing nutrients?

Correct answer: B

Rationale: Rationale: The small intestine is the main organ responsible for absorbing nutrients from the food we eat. It is where the majority of digestion and absorption of nutrients such as carbohydrates, proteins, fats, vitamins, and minerals occurs. The inner lining of the small intestine is covered in tiny finger-like projections called villi, which increase the surface area available for nutrient absorption. The stomach plays a role in breaking down food into smaller particles, but the actual absorption of nutrients primarily takes place in the small intestine. The large intestine mainly absorbs water and electrolytes, while the pancreas produces digestive enzymes and hormones but is not primarily responsible for absorbing nutrients.

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

Correct answer: c

Rationale: Thermal energy is related to the random motion of particles in a substance and is associated with temperature.

3. Which of the following is an example of an aromatic hydrocarbon?

Correct answer: B

Rationale: Benzene is an example of an aromatic hydrocarbon. The other choices are aliphatic hydrocarbons.

4. Which property of matter refers to the measure of the force of gravity acting on an object?

Correct answer: b

Rationale: Weight is the measure of the force of gravity acting on an object. It is calculated as mass multiplied by the acceleration due to gravity.

5. Which word best synonyms with the word "elated"?

Correct answer: C

Rationale: "Elated" and "excited" both convey feelings of happiness and enthusiasm.

6. Which of the following is NOT a function of the endoplasmic reticulum (ER)?

Correct answer: C

Rationale: The correct answer is C: 'Detoxification of harmful substances.' The endoplasmic reticulum (ER) is responsible for synthesizing lipids (fats), transporting materials within the cell, and breaking down cellular waste products. However, detoxification of harmful substances is primarily carried out by the smooth endoplasmic reticulum (SER) where enzymes detoxify drugs and other harmful compounds. Therefore, C is the correct answer as it is not a primary function of the ER.
