Consuming excessive amounts of pure water creates hypotonic environment in the body fluid surrounding the cell.
<h3>
What is a hypotonic solution?</h3>
- A solution having lower osmotic pressure than the solution to which it is compared.
- It has lower amount of solute (high amount of solvent) compared to other solution separated by a semi-permeable membrane.
- After consuming excessive amounts of pure water, the body fluid becomes hypotonic, so water enters from body fluid to the cell resulting in the cell to swell or break.

even though it take 400 years for a paper bag to decompose, people use more plastic.
Answer:
Explanation:
Proteins in the plasma membrane have several functions based on their components, location etc. For instance, if the protein transcends the entire plasma membrane it could be a transport protein, responsible for the import and export of certain molecules between the cell and the extracellular matrix (ECM). If the proteins are resting at the surface of the cell, facing the ECM, their role could be to detect components in the ECM, relaying a series of messages back to the nucleus so that the cell can ‘decide’ what it should do with this information (is it being told it should undergo apoptosis, should it begin to divide, should it migrate?). As well as this, it could be involved in the detection of foreign bodies such as pathogens. This is an extremely job for these proteins because if the cell does come in contact with a pathogen, the cell can use these proteins to engulf the pathogen and through a series of steps, present the antigen on their major histocompatibility complexes (either 1 or 2 depending on the cell type) or HLA’s for human cells. Thus it can be concluded that protein functions vary widely in the plasma membrane and due to the vast number of proteins that can be found there, it’s difficult to narrow down the exact main of functions of all these proteins put together.
