Fluid mosaic is a term used to describe the current model of the cell membrane. Cell membranes are basically double layers (bilayers) of molecules called phospholipids.A mosaic is a structure made up of many different parts.<span> Mainly because of the way the plasma membrane is made up. It is fluid because it can wave and wobble like fluid, a bit sticky though. Due to the phospholipids sticking together. It is called mosaic because there are various proteins stuck inside the fluid creating a kind of patchwork or mosaic </span>
Answer:
there is an increase of the average global temperature due to the accumulation of polluting gases in higher atmospheric levels that causes regional and global climate change.
Explanation:
Cell membrane protects animals cells from harmful chemicals.
Explanation:
The cell membrane is a tough covering composed of the phospholipids and proteins and forms a bilayer around the cells. This acts as a semi-permeable membrane and controls the transport of ions, organic molecules and solutes to and from the cell through selective permeability.
The hydrophilic and hydrophobic properties and the corresponding polarity of the cell membrane and ionization status of the chemicals prevent the entry of harmful substances into the cell. The cell membrane functions as a barrier system and prevents the flow.
The answer is a very good amount.....
