Answer:
Fusion of embryonic myoblasts, each having its own nucleus to many other myoblasts to form the multinucleated skeletal muscle fibers.
Explanation:
The multiple nuclei in skeletal muscle cells are as a result of fusion of embryonic myoblasts, each having its own nucleus to many other myoblasts to form the multinucleated skeletal muscle fibers. This gives rise to multiple copies of genes, allowing production of the large amounts of proteins and enzymes and ATPs needed for muscle contraction.
Answer:
Relative dating
Explanation:
The Law of Superposition of rocks states that the layer of rock which is below is older than the one above it.
Therefore, the type of dating method that can be used on rock layers by applying the law of superposition is relative dating because it is used when the rocks have been kept in their original sequence and not tampered with.
It produces lava, which is what magma is called when it leaves the center of the earth. It exits through a fault or volcano.
