The correct response is: carry and transmit signals.
Nerve cells, also known as neurons, play a crucial role in multicellular organisms by carrying and transmitting signals throughout the body. They are responsible for relaying information between various parts of the body, allowing different organs and systems to communicate with each other. This communication is vital for coordinating and regulating many physiological processes, including sensory perception, motor control, and response to stimuli.
To find the correct answer, it is important to understand the basic function and role of nerve cells in a multicellular organism. Nerve cells are specialized cells that are designed to transmit electrical and chemical signals, known as nerve impulses, across long distances. They have unique structures, including dendrites, which receive signals from other neurons, and axons, which transmit signals to other neurons or target cells, such as muscles or glands.
By understanding the function of nerve cells and their role in transmitting signals, we can identify that the correct response is carrying and transmitting signals.
