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>
<span>All the options (heat, pressure, deposition and chemical environment) are correct.<span>
Metamorphic rocks are formed when pre-existing rocks are subjected to heat, pressure and hot mineral rich fluids which cause physical, chemical and mineralogical changes to the rock. Metamorphic rocks are grouped by chemical, texture and mineralogy. The common metamorphic rocks include schist, marble, and gneiss.

<span>In the six kingdom classification system bacteria are divided into two kingdoms which are known as Archaebacteria and Eubacteria. The archaebacteria are organisms that can dwell in hostile environments like deep sea vents, hot springs, and salt water; while Eubacteria include organisms that can be harmful to humans because they cause certain kinds of diseases like step-throat and botulism.</span>
Answer:
By definition, tissues are absent from unicellular organisms. Even among the simplest multicellular species, such as sponges, tissues are lacking or are poorly differentiated. But multicellular animals and plants that are more advanced have specialized tissues that can organize and regulate an organism’s response to its environment.
