Answer:
Muscle contraction is an example of mechanical contraction.
Explanation:
Muscular contraction is the activation of generating tension which appear in the muscle fiber as it does't change the length of muscle and is followed by muscular relaxation.
Muscle contraction is based on force and length.
The process of skeletal muscle contraction is an energy requiring process.
In order to perform mechanical work,actin and myosin utilizes the chemical energy into ATP that ultimately require during muscle contraction and relaxation.
In a working muscle,glucose is released from glycogen that are stored in the muscle by the process of glycolysis in which glucose broken down into ATP that is required by cells and tissues.
Biofeedback <span>is stress-reduction technique whereby electronic equipment measuring a person’s involuntary (neuromuscular and autonomic) activity helps him gain a level of voluntary control over these processes.
Biofeedback therapy will help you to relax and control involuntary response related to stress like heart rate, sweating, temperature and blood pressure. The electronic equipment will let you know when there is any sign of stress, therefore you know when to calm down yourself.</span>
Answer:
There are many green house gases and carbondioxide is one of them. Green house gas has the ability to stop the heat from going to the atmosphere. This heat energy reduces the atmospheric carbondioxide to dissolve in the ocean water so more concentration of carbondioxide is present in the atmosphere which stop the reflected sunlight rays into the space and thus increase the temperature of the earth surface. This increase in temperature called global warming.
