The following urine results were obtained on a 25-year-old female Color = amber Microscopic: Appearance = cloudy, Bacteria = many ,Specific gravity = 1.015, WBC casts = few ,pH = 5.0, WBC/HPF = 30-40 ,Protein = 1+ ,Glucose = negative ,Blood = small ,These results are most compatible with:

Air enters through the nose (and sometimes the mouth), moves through the nasal cavity, the  pharynx, the  larynx, enters the  trachea, moves through the  bronchi  andbronchioles  till the alveoli.

The rate that would change would be the  searching efficiency/attack rate. there are only two other rates in this model: the  growth rate of prey, and the  predator or consumer mortality rate.the  searching efficiency/attack rate is what indicates how effectively can a predator capture its prey whether in the searching process or actual capturing/attacking process.
