Loop of Henle is the correct answer to that question
Earthquakes are mainly known to occur at plate boundaries where plates converge, diverge or slide past each other. Earthquake activity sometimes accompany volcanic eruptions but these too are concentrated around some plate boundaries (convergent, divergent).
Smaller earthquakes are known to occur in intra-plate regions, away from margins. These occur simply because of stresses being built up in rocks. The crust is solid and rigid and it floats on the mantle which is a curved surface like the crust.
A. Osmosis has to occur through a semi-permeable membrane whereas diffusion can occur through any concentration gradient.
B is incorrect because net movement of osmosis is from area of low concentration to area of high concentration.
C is incorrect because both diffusion and osmosis is a form of passive transport
D is incorrect because the descriptions of osmosis and diffusion are swapped
1. Survival of the fittest
2. Natural selection
