Which layer of soil has little or no humus?

In the layers of the soil that has little humus is the subsoil. The subsoil is the layer after the topsoil. Humus is very important in plants because the humus keeps the moisture of the soil. It makes it easier for plants to drain the excess water as well as allows air to permeate into the soil

the water is warmed up by the sun and then it evaporates into the atmosphere. the sunlight warms the water by its heat. water is then cooled down and condensation takes place. the water then finally returns back to the earth by the process of precipitation in the form of rain or ice.

explanation:

after a the power stroke, adp is released, but the cross-bridge formed is still in place. atp then binds to myosin, moving the myosin to its high-energy state, releasing the myosin head from the actin active site.
