In light chain of antibodies:
Correct answer: A. Variable sequence of amino acid is longer one
- A. Variable sequence of amino acid is longer one
- B. Variable sequence of amino acid is shorter one
- C. Both variable and constant amino acids sequences have equal length
- D. Only variable sequence of amino acids occurs
Explanation
The variable and constant regions differ in length and amino acid composition. The variable region is generally longer and more variable in sequence, whereas the constant region is more conserved and shorter in comparison.

About Homeostasis
Homeostasis maintains a stable internal environment through the kidney and urinary system, thermoregulation and excretion. The kidney topics include filtration, selective reabsorption, urine formation and water balance, while thermoregulation involves sweating, vasodilation, vasoconstriction and hormonal control; excretion is different from egestion, which removes undigested food.
