The continental crust is made mostly of rocks. Both oceanic crust and continental crust are less dense than the mantle, but oceanic crust is denser than continental crust. The mantle, oceanic crust and continental crust have different densities because they are made of different kinds of rock with different densities.<span> the oceanic crust is made mostly of rocks with a composition of basalt.</span>
Function of Ribosomes. Ribosomes are a cell structure that makes protein. Protein is needed for many cell functions such as repairing damage or directing chemical processes. Ribosomes can be found floating within the cytoplasm or attached to the endoplasmic reticulum
For example, in a polarized epithelial cell, the apical surface is the exposed surface and lies opposite to the basal lamina that separates the epithelium from other tissue.
Answer:
B. After clearcutting, plant uptake stopped and nitrogen accumulated in the soil.
Explanation: Clear cutting leaves the soil bare and allows for direct penetration of sunlight this increases the soil temperature which favors the activity of soil microrganism. This microrganism activity increase the production of ammonium and nitrate hence the increase in soil Nitrogen level. Clearcutting then allows for accumulation of Nitrogen produce due to removal of plant or forest tree that could use up the Nitrogen produced.
