Question

Muscle fibres can undergo cell division. True or False. If false correct the sentence. ​

Answer 1

Answer:

Muscle fibers are composed of myofibrils.The filaments of myofibrils consist of two types, thick and thin. The thick filaments are made of the potein myosin. The thin filaments are made of the protein actin.

Answer 2

Answer:

false

Explanation:

skeletal muscle fibers are unable to divide, more of them can be made only by the fusion of myoblasts, and the adult number of multinucleated skeletal muscle fibers is in fact attained early—before birth, in humans. Once formed, a skeletal muscle fiber generally survives for the entire lifetime of the animal.
