In human beings, excretory products in the form of soluble nitrogen compounds are removed by the _____ in the kidneys
Show answer & explanation
Correct answer: A
Explanation
Correct Answer: Option 1 (Nephrons)
Explanation:
In humans, nephrons are the basic structural and functional unit of excretion within the kidneys. These nephrons perform the primary function of filtering nitrogenous wastes (such as urea and uric acid) from the blood. Each kidney contains approximately 1 million tiny nephrons, which help filter soluble wastes and excrete them from the body in the form of urine.
Analysis of Other Options
Urethra: This is the tube through which urine exits the body; it does not perform any filtration function.
ATP: This is the cell's energy currency, providing energy for biological processes.
Xylem: This is the tissue found in plants that transports water and minerals.
