Some types of fish can generate an electric field around their body to communicate with other individuals of the same species (like vocalization in birds). The electric field is generated by cells called electrocytes, which are modified muscle cells. This reflects that: A. behaviors develop over time. B. there is no genetic basis for behavior. C. behaviors are influenced by the environment. D. physiological mechanisms are the basis of behaviors.

D. physiological mechanisms are the basis of behaviors.

Explanation:

The example of the development of electric fields as part of the communication between some fish, shows the interrelation that exists between physiology and behavior. This physiological factor that fish have has an impact on their behavior. However, it is necessary to recognize that physiology does not act by itself, but needs to receive a stimulus from the surrounding environment. This way of communicating is called  electrocommunication, a fish generates through its physiology an electric field and a second individual receives that electric field with its electroreceptors.

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.
