Recall what you know about nervous tissue to answer the following questions. Nervous tissue can generate and conduct ____ signal
Dimas [21]

Answer:

Nervous tissue can generate and conduct <u>electrical</u> signals that control the body.

Explanation:

The neuron is the specialized cell that provides function to nerve tissue. Given the structure of the neuron, this cell is capable of creating and conducting information in the form of electrical impulses or signals, by depolarizing its cell membrane and generating action potentials.

The information generated and transmitted by the neurons allows the nervous system to obtain internal and external information of the organism, as well as to control all the body functions.

<em>     The other options are not true because nerve tissue does not generate or conduct </em><em>thermal </em><em>or</em><em> chemical </em><em>signals to perform its function.</em>
