The three-domain system recognizes fundamental differences between two groups of prokaryotes.
Hope this helps!!
Explanation:
The collaboration of human beings began in the past especially to offer security for offspring. Families living in communities had prolonged life for offspring due to collective security for the benefit of the whole community. Even when some members of community went to hunt or gather food, they are assured to the security of their offspring living in the community. It is believed it is such acts of collaboration that evolved into the current social fabric of society.

Answer: The Relative humidity is 50%
Explanation: Relative humidity is the ratio of the air’s water vapour content (the actual amount of water vapour in the air) to its water vapour capacity at a given temperature. It depends on temperature and the pressure of the system of interest and it is usually expressed in PERCENTAGE; the higher the percentage, the more humid the air/water mixture.
The formula of Relative humidity (%) = (water vapor content / water vapor capacity) x 100%
Where: Water vapour content is the actual amount of water vapour in the air. Which is 10g/cm³ from the question above;
Water vapour capacity is the air's capacity to hold water vapour. Which is 20g/cm³ from the question above.
Therefore, RH(%)= (10g/cm³ / 20g/cm³) x 100 = 0.5 x 100= 50%
This means that the air contains half of the water vapour it could hold at 20 degree Celsius.
