2. The control center of the cell, containing genetic information (DNA), is the:

• A. Golgi apparatus
• B. Ribosome
• C. Nucleus
• D. Endoplasmic reticulum

Correct answer: C

Rationale: The correct answer is C: Nucleus. The nucleus is the control center of the cell as it contains the cell's genetic material, DNA. It acts as the brain of the cell, regulating gene expression and controlling cell activities. The Golgi apparatus is responsible for packaging and processing proteins, the ribosomes are involved in protein synthesis, and the endoplasmic reticulum is essential for protein and lipid synthesis. However, none of these organelles house the genetic information of the cell, making the nucleus the correct answer in this case.

4. What term describes the maximum displacement of particles from their rest position in a wave?

• A. Frequency
• B. Wavelength
• C. Amplitude
• D. Velocity

Correct answer: C

Rationale: The term that describes the maximum displacement of particles from their rest position in a wave is called the amplitude. Amplitude is a measure of the strength or intensity of a wave and is represented by the height of the wave from the rest position to the crest (or trough) of the wave. Frequency (A) refers to the number of complete wavelengths that pass a point in a given time, wavelength (B) is the distance between two consecutive crests (or troughs) of a wave, and velocity (D) is the speed of the wave.

5. What is the name of the curved bone in the back that provides support and attachment for muscles?

• A. Sternum
• B. Scapula
• C. Clavicle
• D. Vertebral column

Correct answer: D

Rationale: The correct answer is D: Vertebral column. The vertebral column, also known as the spine or backbone, is a series of small bones called vertebrae that provide support and protection for the spinal cord. It also serves as an attachment point for various muscles in the back. The sternum, scapula, and clavicle are all bones in the upper body, but they do not specifically provide support and attachment for muscles in the back like the vertebral column does.

6. What is the largest muscle in the human body?

• A. Gluteus maximus (buttocks)
• B. Quadriceps femoris (thighs)
• C. Erector spinae (back)
• D. Pectoralis major (chest)

Correct answer: A

Rationale: The gluteus maximus is the largest muscle in the human body, located at the back of the hip and extending from the sacrum to the femur. It is a powerful muscle that plays a crucial role in extending the hip joint, enabling walking, running, and climbing stairs.
