I did some research and found that the average human requires 550 L of
oxygen per day which means that :
(550 L O2 / day) x (1 day / 24 hours) = 22.9166667 L O2 / hour or
22916.67 mL O2 / hour
1 mL = 1 cm^3
22916.67 mL O2 / hour = 22916.67 cm^3 O2 / hour
Now convert that volume from cm^3 to nm^3
22916.67 cm^3 O2 / hour = 2.29167x10^25 nm^3 O2 / hour
So for 1 hour’s worth of O2, we need a volume of 2.29167x10^25 nm^3
Immunosuppressants, by it's name itself, suppresses or inhibits the immune system for functioning in a certain amount of time. It is administered usually during transplant surgeries, so that the new cells of the organ does not get killed by the recipient's immune system.
Extinction of species reduces the number of different species in ecosystems, hence lowering the diversity of living things.
