I would say the best option would be C. because it’s the most likely option. Realistically speaking, it’s much more likely for a teenage mother to receive the opposite effects mentioned in the other options.
The options to choose from are: portal of exit, reservoir, portal of entry
The answers are JoAnn is the reservoir in the chain of transmission. The mucus from her cough is the portal of exit in the chain of transmission.
JoAnn is the reservoir because the cold is stored in her body. The mucus is the portal of exit because it is being coughed up outside the body.
Answer: False
Explanation:
When there is any dangerous situation or someone is frightened, then the flight and fight system of the body gets activated.
At chemical level the body releases a series of hormones which makes a person alert of the situation. Rather, the respiratory rate, heartbeat, perspiration also increases in the body.
Adrenaline is the hormone responsible for keeping the person alive and alert at this time and to help the body run out of the situation.
The fat and sugar makes our brochi open wider which increases the heart beat and breathing.
Normally the heart beat or heart rate is controlled by the parasympathetic and sympathetic nervous system of the body. The sympathetic nervous system controls the fight and flight part and the sympathetic nervous system controls the rest and digest part of the body.
So, it is the sympathetic nervous system which controls the heart beat of the body at the time of flight or fight, not the homeostasis.
Because when u adopt to change it can save your life
