Natural selection means that the organisms better adapted to their environment, that is, they have developed the right characteristics/skills/response to the external ambient, have higher chance to survive, making the next generations genetically inherit such acquired surviving characteristics.
These generations will thus have a higher chance of survival, making these species being "naturally selected" as survivors, while those who haven't or are slower in this process, have a higher risk of elimination.
The binding of a cell<span> to another </span>cell<span>, or a cell to a </span>surface<span>, via specific </span><span>cell adhesion molecules</span>
Your answer here is Commensalism by process of elimination
