Brainlies explain why the mosses belong in the nonvascular plant's division.

Mosses are nonvascular because they lack the transport systems (xylem and phloem) of vascular plants.  Mosses rely on diffusion, osmosis, and active transport to move water, nutrients, and wastes.  For this reason, they require a moist environment, and are limited in size.

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
