Answer:
65536 cells
Explanation:
starting from 1 cell at zero minutes there will be 1 (2^0) cell; 2^0 = 1
after 15 minutes there will be 2 (2^1) cells
after another 15 minutes ( 30 min) there will be 4 ( 2²) cells
after another 15 minutes ( 45 min) there will be 8 (2³) cells
after n number of 15 minutes there will be (2^n) cells
calculate number of 15 minutes in 4 hours
4 hours = 4 × 60 minutes
number ( n) of 15 minutes in 4 hours = (4 × 60 minutes) / 15 minute = 16
using the formula above and substitute 16 for n in the formula
Number of cells = 2 ^n = 2^16 = 65536 cells

Answer:
True
Explanation:
The sympathetic autonomic nervous system activates the body for hormonal or neuronal responses also known as fight- or - flight response, For example during an fire emergency and there is a need to run. The response occurs primarily by via impulses transmitted through the sympathetic nervous system, and also secondarily through catecholamines secreted from the adrenal medulla.
Although the sympathetic autonomic nervous system is activated in stressful conditions, it needs to be constantly active even at a basal level to maintain homeostasis.
