1. What is the SI unit of measurement for momentum?

• A. Newton (N)
• B. Kilogram-meter per second (kg·m/s)
• C. Joule (J)
• D. Newton-second (N·s)

Correct answer: b

Rationale: Momentum is measured in kilogram-meter per second (kg·m/s).

2. How many bones are there in the adult human skeleton?

• A. 126
• B. 206
• C. 300
• D. 525

Correct answer: D

Rationale: The correct answer is D: 525. The adult human skeleton consists of 206 bones. However, when accounting for individual bones, many of them are paired (like the ribs and vertebrae), bringing the total count to 206 individual bones but 525 in total when considering pairs. This includes bones in the skull, spine, ribs, arms, hands, pelvis, legs, and feet. So, while there are 206 individual bones, the total number of bones in the adult human skeleton is 525 when considering pairs.

3. What is the term for the process of separating the components of a solution based on their different rates of movement through a medium?

• A. Filtration
• B. Distillation
• C. Chromatography
• D. Precipitation

Correct answer: c

Rationale: Chromatography is a technique used to separate the components of a solution based on their different rates of movement through a medium. The other choices are different separation techniques.

4. Which type of cell is responsible for carrying oxygen throughout the body?

• A. Nerve cell
• B. Muscle cell
• C. Skin cell
• D. Red blood cell

Correct answer: D

Rationale: The correct answer is D: Red blood cell. Red blood cells, also known as erythrocytes, are responsible for carrying oxygen throughout the body. They contain hemoglobin, a protein that binds to oxygen in the lungs and transports it to tissues and organs. Nerve cells (option A) transmit electrical signals, muscle cells (option B) are involved in movement, and skin cells (option C) form the outer layer of the skin and provide protection.

5. An object is thrown at an angle. Which of the following forces acts HORIZONTALLY on the object during its flight?

• A. Gravitational force
• B. Normal force from the ground
• C. Air resistance
• D. The force of throwing

Correct answer: C

Rationale: Gravitational force acts downwards, normal force is perpendicular to motion at the launch point, and the throwing force is gone after release. Only air resistance acts continuously to oppose horizontal motion.

6. What is the meaning of the phrase "to be on the same page"?

• A. To be physically close
• B. To agree or understand each other
• C. To be sharing the same goal
• D. To be facing the same direction
