Many biofilm-specific phenotypes are controlled by "quorum sensing." This system allows bacteria to regulate gene expression according to the concentration of bacteria.

Explanation:

Quorum sensing is basically a process which depends upon the density dependent communication of bacteria. Higher the number of bacteria, more will be the communication. Example of quorum sensing is biofilms which grow on various surfaces.

Some auto-inducers like peptides and N-acyl homoserine lactone are produced by bacteria during this process which in turn activate some transcription factors to cause gene expression.

In bacteria, it mainly serves the purpose of bioluminescence, sporulation and nitrogen fixation.

i believe it is c: genes for body color and wing size are inherited separately from each parent.

a scenario where a cell may be needed to perform a form of endocytosis is when transporting large molecules. a scenario where a cell may be needed to perform a form of exocytosis is when releasing the large molecule from the cell.
