Stem cells because they are compatible of dividing and renewing themselves after long periods
The answer is recombination or "crossing over" as some people call it! Hope this helps!
Answer:
vAccording to one data set, the average American has has an ecological footprint over four times larger than the global average.
The right answer is Its striations allow for big movements.
*Skeletal muscle is by definition the muscle that, through the tendon, attaches to the skeleton and allows the movement of the skeleton in a well-defined direction thanks to its essential function of contraction. It has been described, with the first optical microscope observations on tissue in longitudinal section, as a tissue having both transverse and longitudinal striations. Muscle fibers are plurinucleate cells of polygonal shape whose nuclei are located at the periphery of the fiber, attached to the sarcoplasmic membrane. A skeletal muscle fiber is a true syncitium, ie a set of protoplasm fused together. The striated skeletal muscle fiber therefore has the functional characteristics of a giant cell (1-5 cm long, 10-100 μm in diameter).
*Skeletal muscle is a voluntary contraction muscle. Each of the fibers constituting it is a structural syncytium. The intensity of muscle contraction as a whole is a function of the number of motor units that have been activated.
