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:
1. Atmosphere and ecosystem
2. Carbon/CO2 is absorbed by the plants and then released as oxygen.
3. Carbon is used in the cellular respiration process to make ATP.
4. Decomposers break down dead material and release CO2 in that process into the atmosphere for plants to use that carbon for photosynthesis again.
