Answer:
Abstract
Respiratory homeostasis is concerned with the regulation of a blood gas composition that is compatible with maintaining cellular homeostasis. Provided that the lung-capillary exchange barrier does not prevent the exchange of gases, then blood leaving the lung will have oxygen and carbon dioxide partial pressures that are similar to the average values found in the alveoli. Alveolar ventilation establishes these values. If blood gas composition, especially of carbon dioxide, moves outside the homeostatic range, the change is detected by chemoreceptors and respiratory responses are promoted which change alveolar ventilation, alter alveolar gas composition and so reverse the change. Ventilation therapies provide the means of artificially restoring alveolar gas composition. In general terms, they do this by raising the partial pressure of oxygen within the alveoli either by using oxygen-enriched gas mixtures, or by improving the ventilation of alveoli using positive pressure.

Answer:
The black and yellow bird population would begin to starve and would be forced to find alternative food, or die off. This would then send ripples through the food web, causing almost every species to be effected by the grasshoppers being gone.
Traditionally used as a thickening agent in lotion, this vegetable derived waxy substance is also used as a hardening agent in soaps (at a .5% of your oils as a usage rate). Stearic acid is also used as a hardening agent in candles, vegetable or paraffin based.
Answer:
Bacteria that are non-controlled or destroyed by antibiotics are antibiotic-resistant bacteria. In the presence of an antibiotic, they will live and even develop. At least certain antibiotics can become immune to most infection-causing bacteria.
Explanation:
Some bacteria are immune to such antibiotics naturally. In most species found within the human digestive system, for example, benzylpenicillin has very little impact.
