Probable Cause. The Fourth Amendment provides that no warrants shall issue, but upon probable cause.. The Constitution doesn't furnish any definition of probable cause, leaving that task to the Supreme Court, which has also applied the probable cause standard to certain warrantless activities.
Exercise increases the rate and depth of breathing. The heart rate increases during exercise. The rate and depth of breathing increases-this makes sure that more oxygen is absorbed into the blood, and more carbon dioxide is removed from it.The rate of breathing can be measured by counting the number of breaths in one minute.xercise increases the rate and depth of breathing. The heart rate increases during exercise. The rate and depth of breathing increases-this makes sure that more oxygen is absorbed into the blood, and more carbon dioxide is removed from it.
1 The increased rate of breathing returns the carbon dioxide concentration to normal and the breathing rate then slows down.  Hydrogen ion (pH): The peripheral and central chemoreceptors are also sensitive to the pH of the blood and CSF. If the hydrogen ion concentration increases (that is, if the fluid becomes more acidic), then the chemoreceptors tell the respiratory centers to speed up.
