Scientists are studying cell-to-cell communication in a human spleen. How would scientists most likely use technology during this study?

to draw a diagram showing how cellular communication occurs
to predict what triggers cells-to-cell communication
to determine safety procedures to be used in the laboratory
to determine the number of visible cells by counting them

To predict what triggers cell-to-cell communication

Explanation:

Methodologies used for studying cell-to-cell communication includes

1) The reductionist method in which cellular response are measured based on testing specific cellular signals by the introduction of different chemicals, so as to find the source that triggers the response

2) By the application of known chemical reagents enable or block specific areas of an organism's receptors and with the aid of an electrode measure the cellular response based on generated currents of ions or by collecting and analyzing fluid samples from the affected area.
