How do nerve cells form different types of tissues? A. A group of these cells perform similar functions and become nerve tissue after information in the DNA of the nucleus tells the nerve cells to develop and perform special functions. B. A group of these cells perform similar functions and become nerve tissue after messages from the brain tell nerve cells how to develop and perform special functions. C. A group of these tissues perform similar functions and become nerve organs after messages from the heart tell nerve cells to develop and perform special functions.
