Which of these is not true about myotubes a. Myotubes join to form muscle fiber b. Multiple myotubes join to form myocytes c. Myotubes are multinucleated d. Myotubes are electrically active​

Answer 1

Explanation:

A strong friendship does not need daily conversation, does not always need togetherness. As long as the heart, true friends will never part.

Answer 2

b) Multiple myotubes join to form myocytes is not true about myotubes.

Formation of myotubes:

• Additional myoblasts line up along the primary myotubes as the muscle grows, and they eventually unite to form secondary myotubes.
• These begin to form around halfway between the ends of the principal myotubes, and as new myoblasts are added, they quickly lengthen.

Development of muscle from myotube:

• Myoblast precursors fuse to generate multinucleated fibres known as myotubes, which are the basic building blocks of muscle fibres.
• Myoblasts have two early developmental options: they can either multiply or grow into myotubes.
