Explanation:

A nephron is the basic structural and functional unit of the kidney. Its main functions are to filter blood, reabsorb necessary substances (like water, glucose, and salts), and secrete waste products to form urine.

• The unit of measurement for electrical resistance is the ohm.
• White blood cells are part of the immune system (e.g., lymphocytes, neutrophils).
• Proteins in muscle tissue include actin and myosin.
