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. The final sentence highlights the need for

Correct answer: C

Rationale: The emphasis on "international cooperation," "robust scientific research," and "adapting" suggests a focus on collaborative and multi-faceted solutions, aligning with C.

3. The outermost layer of your skin, responsible for waterproofing and providing a barrier against pathogens, is the:

Correct answer: B

Rationale: The correct answer is B: Stratum corneum. The stratum corneum is the outermost layer of the epidermis, consisting of dead skin cells (corneocytes) that are continuously shed and replaced. This layer is responsible for waterproofing the skin and providing a barrier against pathogens, UV radiation, and other environmental factors. The stratum basale (A) is the deepest layer of the epidermis where new skin cells are produced. The stratum granulosum (C) is the layer of the epidermis where cells begin to flatten and keratinization begins. The stratum spinosum (D) is the layer above the stratum granulosum, where cells become interconnected by desmosomes. Therefore, the stratum corneum is specifically designed to fulfill the functions of waterproofing and protecting against pathogens.

4. Explain how a single gene mutation can lead to multiple phenotypes depending on the organism.

Correct answer: A

Rationale: A single gene mutation can affect different biochemical pathways or developmental processes, leading to a cascade of downstream effects and diverse phenotypic consequences.

5. What is the formula to calculate kinetic energy?

Correct answer: a

Rationale: Kinetic energy is calculated using the formula KE = ½ × mass × velocity².

6. What is the process by which a large, unstable nucleus splits into two smaller nuclei, releasing neutrons and energy?

Correct answer: D

Rationale: Nuclear fission involves splitting a heavy nucleus into smaller fragments, releasing neutrons and energy.
