<span>enzymes are resuable as they are biologically catalyst which speeds up the rate of a reaction without being chemically changed themselves. However, if the enzyme is to be denatured under unfavourable conditions (extreme temperatures, extreme pH), the enzymes may not be reusable once denatured.</span>

Answer:
Option B, by saltation in the first few meters above the land surface
Explanation:
In the process of saltation, sand is carried by air and the sand grains remains suspended for a small distance till the fall down. These sand grains form a parabolic trajectory before falling down. The other characteristics such as height and time of suspended grains depends on grain size, shape, and density, lift & drag force and characteristics of wind such as velocity and turbulence.
Hence, option B is correct
