Muscles require more energy even if they are not very active in the moment because ATP or energy is needed for their relaxation.
Explanation; Relaxation of muscles takes place when the stimulation of nerves stops. Calcium is then taken back into the sarcoplasmic reticulum breaking the link between actin and myosin. Actin and myosin return to their unbound state causing the muscle to relax. ATP is involved in displacing actin from myosin head. Therefore; ATP is required for muscle relaxation.
Flowers and cones have different structures. Cones when mature have a woody texture and is made up of scales while flowers have colorful petals, sepals and both male and female reproductive portions are called stamens and pistils.
