Phospholipids are the outermost layers of animal cells. Its structure is composed of fatty acid chains that are attached to a glycerol backbone, and a phosphate group that is modified by an alcohol.
The polar end of the phospholipid plasma membrane is hydrophilic (water-loving or can absorb water) and is a negatively charged phosphate group. In the cell they are facing outward, attracting intracellular and extracellular fluid.
The non-polar tails of the phospholipid are fatty acid chains that are hydrophobic (water-fearing or unable to absorb water). The tails are facing the inside of the cell away from water towards the inner membrane of the cell.
The answer is <span>the atomic number and the mass number will decrease.

When atoms undergo radioactive decay, alpha particles release.
Alpha particles consist of two protons and two neutrons. So, mass is 4 (2+2) amu

When an atom of emits an alpha particle, its atomic number will be reduced by 2 and a mass number will be reduced by 4:</span>

Really it matters on which head you start the flip on. Whichever head you start with, there's a 51% chance to land on that one. If you start with heads, it would be 255 times.
