4 The ability of a geckos to climb smooth vertical surfaces is primarily due to microscopic structures on their toe pads called setae, which create what type of force?

A Magnetic attraction
B Electrostatic forces
C Van der Waals forces
D Gravitational pull

5 The design of a bird's feather, with its interlocking barbules, is an example of a lightweight yet strong composite structure. This biomimicry principle is akin to which engineering material concept?

A Solid-state physics
B Laminated composites
C Superconductivity
D Thermodynamics

6 The movement of water through the xylem vessels in plants, like the transpiration pull, relies on cohesive and adhesive forces. This phenomenon is a demonstration of which engineering principle?
