First increases then decreases.
Explanation:
The speed of skater tends to increases when it moves from high elevation of 6 m to the low height area due to sloppy region while on the other hand, when the skater moves again from 0 m or from the ground level to 6 m height its speed decreases when reaches to the highest point. First the speed of the skater increases due to moving in the direction of gravity while on other hand, the speed of the skater decreases due to movement of skater against the gravity of earth.
Vestigial structures are considered evidence since scientists believe they are structures that were once used by a species ancestors but are no longer needed. They do not impair the organisms in any way, so there is no need for evolution to get rid of them. Vestigial structures are anatomical features that no longer seems to have a function or purpose in the current form of an organism of the given species. Examples are wisdom teeth, the muscles of the ear, the appendix, the tail bone among others in human.

Onion skin is a plant cell. And your skin cell is a animal cell.
Basically as simple all the structures in animal cell can be found in plant cells. But plant cells has some extra structure and part where doesn't exist in animal cells.
In animal cell, it contains a cytoplasm, nucleus and a cell membrane.
But in plant cell, they have chloroplast, cell wall and vacuole in additional.
According to simple diffusion. Molecules travel from high concentration to low. So it would be traveling into the cornea
