Answer : The number of beats (N) in the lifetime is beats.
Explanation :
First we have to determine the life time (T) of the person in the unit of minutes.
T = 70 year = (70 × 365 × 24 × 60) minutes
Conversions used :
1 year = 365 days
1 day = 24 hours
1 hour = 60 minutes
As we are given the rate (R) of the heart beat is, 70 beats/minutes.
R = 70 beats/minutes
Now we have to determine the number of beats (N) in the lifetime.
N = RT
N = (70 beats/minutes) × (70 × 70 × 365 × 24 × 60) beats
N = beats
Therefore, the number of beats (N) in the lifetime is beats.

There is a wide diversity of life teaming around hydrothermal vents. These communities include primary producer organisms, but instead of obtaining energy from the sun, these bacteria use a process called chemosynthesis to convert minerals and other chemicals in the water into energy. These bacteria support a wide range of other animal species, including giant tube worms, deep sea mussels, serpulid or “feather duster” worms, and vent crabs, the apex predator of the vent community.
