Rotation is the act of raising the nose of an aircraft (by pulling back slightly on the control yoke or stick) during the take-off roll, so that it leaves the runway. Rotation allows for a precise, positive departure from the runway.
Crenation is the loss of water from an animal cell due to osmosis. Lysis is the rupture of the cell wall due to too much water moving into an animal cell due to osmosis. Both â¦crenation and lysis have drastic effects on the animal cell.
During episodes of apnea though, where the body forcibly slows or shuts down breathing entirely in spurts, this can lead to dangerously high levels of carbon dioxide in the blood, and could lead to death in the most serious cases. Hypoventilation can be caused by numerous factors. These may be caused by natural obstructions in the airway, or resistances to sufficient airflow. These are commonly brought on by other medical conditions that result in lower airway obstruction, including emphysema, cystic fibrosis and bronchitis.
