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.
Answer:
Someone whose job involves manual labor would have noticeably larger and stronger upper body bones because it has adapted to the everyday activities every day. That is to say, that the body has become larger and stronger to perform the tasks efficiently.
Explanation:
The body adapts itself to our activities. If our job does not involve manual labor, our upper body does not need to have noticeably large and stronger upper body bones. Since it is not manipulating heavy things or moving constantly, there is not an external factor that shapes it this way. Besides, the constant physical work will shape the body to do the job more efficiently and without damaging it.
