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.

Does a carbon monoxide detector go off continuously
Zielflug [23.3K]

Answer: CO alarms have a life expectancy of around seven years. The CO alarm will beep every 30 seconds or display ERR or END. If a CO alarm is at its end-of-life, replacing the battery will not stop the beep. Most detectors will beep 4 or 5 times in a row about every 4 seconds. Do not mistake dangerous levels of poisonous gas for a detector with low battery.

Explanation: (credits to the internet) Hope this helped! :D
