The examples of cellular communication used in this activity vary from bacteria to plants to ver- tebrates. However, the mechanisms of cellular communication are similar among varied species. Explain how scientists might use cellular communication systems to show evolutionary related- ness between species.

Respuesta :

Explanation:

The cellular communication is an important aspect of unicellular and multicellular organisms in the environment. The cellular communication may differ in the bacteria, plants and animals but the mechanism of cellular communication remains the same.

The mechanism involves the receptors, change in the structure of receptors which triggers the signal to respond and then the response of the cell. Therefore the evolutionary biologists must look at this mechanism and the molecules associated with this mechanism.

The biologist can look at these receptors and the ligands which initiate the transduction process in the organisms.

The scientists uses cellular communication systems to show evolutionary relatedness between species:

  • Cellular communication is an important aspect of unicellular and multicellular organisms in the environment.  
  • Cellular transmission can be different in  bacteria, plants and animals, but the mechanism of cell transmission remains the same.
