2. Hematopoietic tissue is responsible for

Correct answer: C

Rationale: Hematopoietic tissue is responsible for the production of blood cells. This specialized tissue is found in the bone marrow and is crucial for the continuous generation of red blood cells, white blood cells, and platelets. These blood cells play essential roles in oxygen transport, immune defense, and blood clotting. Building and repairing bone (option A) is primarily the function of osteoblasts and osteoclasts in bone tissue. Supporting and connecting tissues (option B) is the role of connective tissues like tendons and ligaments. Contracting for movement (option D) is the function of muscle tissue. Therefore, the correct answer is C, as hematopoietic tissue specifically focuses on blood cell production.

3. What property of a wave remains unchanged when it passes from one medium to another with the same speed?

6. Which of the following organs is responsible for the mechanical breakdown of food into smaller pieces?

Correct answer: D

Rationale: The correct answer is D: Mouth. The mouth is responsible for the mechanical breakdown of food into smaller pieces through the process of chewing. The teeth in the mouth help to grind and crush food into smaller particles, making it easier for digestion to occur. The esophagus is a muscular tube that transports food to the stomach but does not contribute to mechanical breakdown. The stomach is responsible for further breaking down food using acid and enzymes, while the small intestine is mainly involved in the absorption of nutrients. Therefore, the mouth plays a crucial role in the initial mechanical digestion of food.
