In addition, most states set a minimum. threshold for waiver eligibility: generally a. minimum age and a specified type or. level of offense, and sometimes a suffiÂ­. ciently serious record of previous delinÂ­. quency. Waiver thresholds are often quite. low, however.
The digestive tract is dependent upon the respiratory system, because your digestive tract functions by using muscular contractions to break up food and move it along the tract. Smooth muscle in the stomach churns food into a liquid, and contractions of the intestine move food through the system.our digestive and respiratory systems, at first glance, seem very separate in their activities. In reality, however, the systems work together intimately in several ways. The results of respiratory activity allow the digestive tract to function, and vice versa.
4. Some cells that usually obtain energy from aerobic cellular respiration can use fermentation when oxygen is not available. There are bacteria and fungi that, in the absence of oxygen, use their anaerobic metabolic capability for energy supply. Muscle cells also use fermentation when oxygen is scarce.hen ATP provides energy to the cellular metabolism, it releases one of its phosphate ions and ADP reappears. ADP can also release more phosphate ions and generate AMP (adenosine monophosphate) or even non-phosphorylated adenosine.
