It is found in the walls and histological foundation of the heart. Which one of the following statements is not related to the cardiac muscles? a) They muscles show rhythmic contraction and relaxation throughout life. b) They do not work according to our will, so they are called involuntary muscles. c) They are non-striated, multinucleated and branched muscles. d) The contraction and relaxation of the heart muscles help to pump and distribute blood to different parts of the body. 5) Xylem is the specialized tissue of the plants that transports water and nutrients from the soil to the upper parts like stems and leaves of plant and provides mechanical support to them.
