2. What is the main component that gives bones their rigidity and hardness?

• A. Collagen
• B. Calcium phosphate
• C. Cartilage
• D. Ligaments

Correct answer: B

Rationale: The main component that gives bones their rigidity and hardness is calcium phosphate, which is a mineral compound found in bone tissue. While collagen is a protein that provides flexibility and strength to bones, it is the calcium phosphate that primarily contributes to the hardness and rigidity of bones. Cartilage is a connective tissue that cushions joints and helps with movement, while ligaments are fibrous tissues that connect bones to other bones. Therefore, calcium phosphate is the correct answer as it directly relates to the rigid and hard nature of bones.

3. Which part of the neuron receives signals from other neurons and conducts them toward the cell body?

• A. Axon
• B. Dendrite
• C. Synapse
• D. Myelin sheath

Correct answer: b

Rationale: The correct answer is B: Dendrite. Dendrites are the part of the neuron that receive signals from other neurons and conduct them toward the cell body. They have numerous branches and are covered in synapses, allowing them to receive signals from multiple neurons. The axon, on the other hand, conducts signals away from the cell body towards other neurons or to muscles or glands. The synapse is the junction between two neurons where communication occurs, and the myelin sheath is a fatty layer that insulates and speeds up the conduction of electrical impulses along the axon. Therefore, the dendrite is specifically designed to receive and integrate incoming signals, making it the correct answer in this case.

4. What is the formula to calculate work?

• A. Work = Force × Distance
• B. Work = Mass × Velocity
• C. Work = Power × Time
• D. Work = Energy ÷ Time
