Answer:
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.
C. ferns.
Explanation:
The ferns are ancient plants that have managed to survive until the present. They are not closely related to the dominant plants nowadays, the flowering plants, but instead they are closely related with plants that have gone extinct tens and hundreds of millions years ago. Even though the ferns are not the dominant plants, they have managed to find a niche and firmly hold onto it, so they remained widespread, normally occupying the lower layers of the forests.
Unlike the flowering plants that produce flowers and then seeds in order to reproduce, that is not the case with the ferns. The ferns actually reproduce through spores, being widely dispersed by the wind and managing to spread out and reproduce over relatively large territory very quickly.
Muscle cells need a specific form of energy for contraction and cannot use the energy released directly from breaking down glucose or triglycerides. Rather, body cells must first convert food to adenosine triphosphate (ATP). <br /><br /> Food is digested and processed into ATP through sever different stages.
