Answer:
Parasympathetic nervous system
Explanation:
Parasympathetic nervous system (PNS) along with sympathetic nervous system (SNS) makes autonomic nervous system (ANS). ANS controls the functioning of internal processes like digestion rate, heart rate, respiratory rate etc. During a threat or stressful situation SNS is activated. It increases heart rate, respiratory rate and directs blood flow towards peripheral muscles as a part of "fight or flight response". When the situation becomes normal, PNS is activated which restores all the vitals as a part of "rest and digest" mechanism.
Since here Byron almost got into an accident, he was scared a lot due to which his SNS was activated. Eventually when he realized that he is out of danger, his PNS got activated which returned his heart rate and blood pressure to normal levels.

Answer:
The carbon dioxide reacts with water to form carbonic acid.
Explanation:
CO2+H2O=H2CO3
In this reaction carbon dioxide(CO2) and water(H2O) act as reactant to form carbonic acid(H2CO3) which is a weak acid.
The above reaction is an important reaction carried out by bicarbonate buffer system to maintain normal acid base balance inside our body but this buffer system includes an additional reaction in with carbonic acid is ionized to form H+ and HCO3- ion or bicarbonate ion.
