During development embryonic cells will fuse to form muscle fibers. this will result in

a. the striations that appear in skeletal and cardiac muscle tissues
b. the coordination of nerve signals to muscle fibers
c. multinucleated muscle fibers that can extend as long as 30 centimeters
d. interlocking of cells that can prevent the filaments from sliding

c. multinucleated muscle fibers that can extend as long as 30 centimeters

Explanation:

The muscle is formed by specialized cells whose function is contraction; Its development begins at a very early stage, during the embryonic period, when the conceptus is in gastrulation phase. It is composed of cells with several nuclei (multinucleated) long up to 30 cm and cylindrical that contract to facilitate the movement of the body and its parts. Your cells have a lot of mitochondria. Most of the muscles are formed from paraaxil (somitic) mesoderm and splanchnic mesoderm, with the exception of some, such as iris muscles, whose origin is the neuroepithelium .

According to their function and histological characteristics, three varieties of muscle are considered: skeletal (or striated), smooth and cardiac. There are also other cells whose function is similar to that of the muscle called myoepithelial cells that derive from the ectoderm and are located in some external secretion glands in which the contractile function is required for ejection of its content, such is the case of the parotid , submaxillary glands and mammary gland, among others.

wheres the answers ?

100 dollars because yeah
