Secondary consumer is the answer.
The receptor molecule is the ones which allow different interaction to occur between the matrix and the cell.
<u>Explanation:</u>
Receptor molecules are the protein molecules that have the ability to bind the signaling molecules at the surface of the cell in order to send signals to the matrix. Those signals on receipt<em> </em>act as the channel of communication.
Thereby, the interaction between the cell and matrix is established. Usually, this is one of the kinds of interaction. Paracrine interactions are interaction within adjacent cells whereas the endocrine interactions are interaction with distant cells.
The blue-white screen refers to a procedure of screening that allows for the brisk and convenient determination of recombinant bacteria in vector-based molecular cloning experiments. In the process, the DNA of interest is ligated into a vector. The blue colonies constitute of self-relegated plasmids that are devoid of DNA inserts obstructing the lac Z gene.
The white colonies contain bacteria that conduct plasmids, which possess the inserts of DNA fragments that obstruct the lac Z gene. Therefore, the researcher needs to sequence the plasmids of the white colonies prior to knowing which allele it constitutes.
