Mathematics

1. A decorative box has a rectangular base (20cm by 15cm) and a hemispherical top with the same diameter as the base. What is the total surface area of the box (excluding the base)?

Correct answer: C

Rationale: Calculate the surface area of the lateral sides and the hemisphere, then add them up.

2. The spleen, an organ associated with the lymphatic system, plays a crucial role in:

Correct answer: B

Rationale: The correct answer is B: 'Filtering blood and destroying old red blood cells.' The spleen is part of the lymphatic system and acts as a blood filter, removing old or damaged red blood cells and helping to fight infections. It does not play a role in regulating blood sugar levels (A), producing digestive enzymes (C), or secreting hormones (D). Understanding the function of the spleen in filtering blood and removing old red blood cells is crucial for grasping its role in maintaining overall health and immunity.

3. 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.

4. A lab needs 200ml of a 5% salt solution. They only have a 10% solution. How much 10% solution and water should be mixed?

Correct answer: B

Rationale: Rationale: 1. Let x be the volume of the 10% solution needed and y be the volume of water needed. 2. The total volume of the final solution is 200ml, so x + y = 200. 3. The concentration of the final solution is 5%, so the amount of salt in the final solution is 0.05 * 200 = 10g. 4. The amount of salt in the 10% solution is 0.1x, and the amount of salt in the water is 0, so the total amount of salt in the final solution is 0.1x. 5. Since the total amount of salt in the final solution is 10g, we have 0.1x = 10. 6. Solving for x, we get x = 100ml. 7. Substituting x =

5. Which organ plays a significant role in immune cell production and maturation?

Correct answer: C

Rationale: The correct answer is C: Bone marrow. The bone marrow is the primary site for the production and maturation of immune cells, including white blood cells, which are crucial for the body's immune response. Stem cells in the bone marrow differentiate into various types of immune cells, such as T cells, B cells, and natural killer cells, which play essential roles in fighting infections and diseases. While the liver and kidneys have other important functions in the body, such as filtering toxins and metabolizing substances, they are not directly involved in immune cell production and maturation. The spleen acts as a reservoir for blood and is involved in filtering blood and storing red blood cells but is not the primary site for immune cell production.

6. What is the process of breaking down proteins into amino acids called?

Correct answer: A

Rationale: Rationale: Proteolysis is the process of breaking down proteins into amino acids. Lipolysis is the breakdown of fats into fatty acids and glycerol, not proteins. Carbohydrate catabolism involves the breakdown of carbohydrates into glucose for energy production. Nucleic acid catabolism is the breakdown of nucleic acids into nucleotides. In this context, the specific process of breaking down proteins into amino acids is best described by proteolysis.
