Sagot :
Oxygen is the crucial gas required for an organism to carry out the cellular process. The seal can dive for 4 minutes before it runs out of oxygen. Thus, option a is correct.
What is oxygen consumption?
Oxygen is the most vital element of the organism that is required by almost all cellular and metabolic activities. It is inhaled by the respiratory system and passed to cells and tissues through the circulatory system.
Given,
Mass of seal = 100 kg = 100000 gm
Rate of oxygen consumption (r) = 1 ml/ (gh)
The volume of the stored O₂ = 7000 mL
The time (t) is calculated as,
t = V ÷ mr
Substituting the values above,
t = 7000 ÷ 100000 × 1
= 0.07 hour
In minutes it will be given as,
0.07 × 60 = 4.2 minutes
Therefore, option a. 4 minutes is the time till the seal can remain underwater without oxygen.
