question 70

Multiple Choice

Some types of fish have specialized cells called electrocytes that generate an electric field around their body, with which they can communicate with other individuals of their own species. The electrocytes become functional when specialized Na⁺ channels are inserted into their plasma membrane. Because sodium channels are proteins, we can conclude that the behavior of generating an electrical field for communication:

• A)has a genetic basis because proteins are produced through gene expression.
• B)is a learned behavior.
• C)is dependent on environmental conditions.
• D)does not change regardless of input from the environment.
• E)does not have a genetic basis because proteins are produced independent of the genome.
