What is the difference in the beginning between primary succession amd secondary succession

Biology

lianna [129]3 years ago
4 0
Primary succession is when, for example, a volcano explodes and there is nothing left and even the soil is ruined. It would take at least a hundred years for the land to be like it was before the volcano erupted. Secondary succession is when, for example, a wild fire happens but the soil is not ruined. It would take at least 25-50 years for the land to be like it was before the fire.

If you tore some of your muscle cell protein fibers what would the cell need to do to repair the damage?
Svet_ta [14]

Answer:

the cells fuse with existing muscle fibres, to regenerate and repair the damaged fibres

Explanation:

The muscle damage initiates a repair process in which certain hormones, along with the macronutrient protein, synthesize new satellite cells, which are used to repair the damaged muscle fibers. In other words, the role of protein is to help repair tissues damaged by exercise.  When the muscle is damaged, these cells are stimulated to divide. After dividing, the cells fuse with existing muscle fibres, to regenerate and repair the damaged fibres. The skeletal muscle fibres themselves, cannot divide. However, muscle fibres can lay down new protein and enlarge (hypertrophy).
