The student is wrong. Phosphorylation
cascade is important in cell signaling. Most cell signaling involves cyclic AMP (synthesized from
ATP). The cAMP activates Protein Kinases (PKA)
that phosphorylates protein
substrates involved in the signaling pathways
such as the GPCR. This helps in amplifying the initial signal.
Normally the amount of plasma in whole blood is GREATER than the amount of formed elements: plasma makes up approximately -55- percent of whole blood.
Hope this helped!
Weathering is a natural process by which the surface mineral of rocks is carried away by various agents .The agents can be water,wind,and ice. weathering means disintegration of rocks and the small parts are being carried away by these agents and are found on different places.Weathering of rocks depends on the many factors such as climatic conditions,type of rock,water availability and many more.The small rocks mix with soil and helps form sediment .This sedimentation helps to shape the earth's surface.This is an important part of rock cycle and is very important.
