Answer: A low pCO2 indicates respiratory alkalosis which may be primary or secondary to a primary metabolic acidosis. Bicarbonate is calculated from measured [H+] and pCO2 values. A high standard [HCO3- ] indicates either primary metabolic alkalosis or a compensatory response to a primary respiratory acidosis.
Explanation: an increase in PCO2 causes a decrease in pH, which will increase minute ventilation and therefore increase alveolar ventilation to attempt to reach homeostasis. The higher the minute ventilation, the more exchange and loss of PCO2 will occur inversely.
 
        
             
        
        
        
Answer:
Energy is said to flow in a "one-way stream" through an ecosystem. In your own words, describe what that means. Energy is not recycled. Energy enters an ecosystem and flows through a food chain, but it is not reused, it is lost as heat.
