Explanation:
Cellular Metabolism
The living cells of every organism constantly use energy to survive and grow. Cells break down complex carbohydrates into simple sugars that the cell can use for energy. Muscle cells may consumer energy to build long muscle proteins from small amino acid molecules.
Answer:
proprioceptor
Explanation:
Proprioceptors are the receptor located in a joint, muscle, or tendon. These receptors are concerned with locomotion, posture, and muscle tone. These receptors respond to internal stimuli only and are present in a specific location in the body. For example, the tendon organ is a proprioceptor present in the tendon. The function of the tendon organ is to monitor the muscle tension and to prevent its tearing. These receptors also help smooth start and termination of muscle contraction.
Proprioceptors are the mechanoreceptors that regulate the body’s equilibrium and posture by their role in reflex actions that maintain muscle tone. They sense the position of limbs by detecting the degree of muscle relaxation, the stretch of tendons, and ligament movements.
The mudflows are very dangerous and they have a great destructive power. They appear after a heavy rainfall on places that are steep. The mudflows are very fast and sudden occurrences, so usually people are caught unprepared. A mudflow is a mixture of water and lot of ground/mud, and all sorts of debris, which also contributes to it to be more dangerous.
