Answer:
Please see below
Explanation:
It doesn't change much because as opposed to other mineral cycles, phosphorus does not have a gas compound and thus there is not a significant storage of phosphorus in the atmosphere. Under such scenario, whatever phosphorus can be found in the atmosphere such as windborne soil particles or pollen grains becomes important. A third component that needs to be mentioned is the ocean. River runoff is the main source of phosphorus input to the ocean from which phytoplankton incorporates it into the food chain.
I’m not exactly sure, but I’m thinking it may be A . I just learned about this unit previously .

Explanation:
The cell membrane (also known as the plasma membrane (PM) or cytoplasmic membrane, and historically referred to as the plasmalemma) is a biological membrane that separates the interior of all cells from the outside environment (the extracellular space) which protects the cell from its environment.[1][2] The cell membrane consists of a lipid bilayer, including cholesterols (a lipid component) that sit between phospholipids to maintain their fluidity at various temperatures. The membrane also contains membrane proteins, including integral proteins that go across the membrane serving as membrane transporters, and peripheral proteins that loosely attach to the outer (peripheral) side of the cell membrane, acting as enzymes shaping the cell.[3] The cell membrane controls the movement of substances in and out of cells and organelles. In this way, it is selectively permeable to ions and organic molecules.[4] In addition, cell membranes are involved in a variety of cellular processes such as cell adhesion, ion conductivity and cell signalling and serve as the attachment surface for several extracellular structures, including the cell wall, the carbohydrate layer called the glycocalyx, and the intracellular network of protein fibers called the cytoskeleton. In the field of synthetic biology, cell membranes can be artificially reassembled
