Clear cutting can result in increased carbon dioxide levels in the atmosphere.
Explanation:
Clear cutting of trees increases the amount of carbon dioxide. Trees are useful in balancing the concentration of carbon dioxide in the atmosphere. They trap carbon dioxide that is used during photosynthesis in the manufacture of carbohydrates. When there is deforestation, the excess carbon dioxide rises to the atmosphere forming a blanket that traps excess heat which causes global warming or greenhouse effect. The excess heat warms the aerth surface.
The process of muscle contraction requires several steps.
The most famous theory on how the contraction and relaxation of muscles take place is the sliding filament theory.
However, this theory has been refined and one important addition to it is the mechanism by which myosin can pull actin and cause shortening of the sarcomere.
For the movement of myosin, it binds and releases actin and forms cross bridges.
Myosin is subdivided into two regions - S1 and S2. The contraction of the S1 region is what constitutes the power stroke.
An important requirement of the power stroke is the hydrolysis of ATP to release an inorganic phosphate which provides energy for the process.
