What is the primary function of the heart in the human body?
Correct Answer
C. Pumping blood
Explanation
The heart's primary function is to pump blood throughout the body, a critical process that sustains life by transporting oxygen, nutrients, hormones, and other essential substances to various tissues and organs. As the central component of the cardiovascular system, the heart operates as a muscular organ, contracting rhythmically to ensure continuous blood circulation. This action not only delivers necessary resources but also aids in the removal of metabolic wastes like carbon dioxide. The efficiency of this process is vital for maintaining the body’s homeostasis and overall health, highlighting the heart's role as a fundamental organ.

Who developed the theory of general relativity?
Correct Answer
C. Albert Einstein
Explanation
Albert Einstein revolutionized our understanding of the universe with his development of the theory of general relativity in 1915. This theory advanced the concept that gravity is not merely a force but a distortion of space and time caused by mass and energy.

What is the smallest bone in the human body?
Correct Answer
A. Stapes
Explanation
The stapes, located in the middle ear, is the smallest bone in the human body. It measures about 3 millimeters in length and plays a crucial role in hearing by transmitting sound vibrations from the eardrum to the inner ear. The stapes connects to the oval window, amplifying sound waves for the cochlea to process. Its tiny size and unique shape, resembling a stirrup, make it anatomically efficient for its function. In comparison, larger bones like the femur provide structural support, while the stapes is specialized for auditory mechanics, emphasizing the diversity in bone functions.

What is the chemical symbol for gold?
Correct Answer
A. Au
Explanation
Gold’s chemical symbol, Au, comes from its Latin name "aurum," meaning "shining dawn." Gold is a highly valuable element due to its rarity, malleability, and resistance to corrosion. It has an atomic number of 79, and its unique properties make it essential in jewelry, electronics, and finance. Unlike other elements like Fe (iron) or Pb (lead), gold’s inertness ensures it doesn’t tarnish, maintaining its luster over time. Chemically, gold's stability arises from its filled electron shells, making it unreactive under normal conditions. This stability and beauty have contributed to gold's historical and economic significance.
