GATE 2024 BM – Question 42
Identical engineered tissues X,Y,Z were co-cultured with different native tissues: I liver,II articular cartilage,III devitalized bone. At eight weeks their adhesive strengths were X=150,Y=250,Z=350 kPa. Choose the source’s intended matching.

Show answer and explanation
Correct answer: (A) X–I,Y–II,Z–III
Explanation
The source expects the integration-strength ordering liver<articular cartilage<devitalized bone, reflecting the increasing stiffness/mechanical support of these substrates in this comparison. Thus the lowest value X maps to liver, intermediate Y to cartilage, highest Z to bone, A. Adhesion is not determined by stiffness alone in arbitrary experiments; the answer is the intended tissue comparison under the stated identical engineered-material conditions.
