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.

Answer:
The complementary base pair is ATG  TTT   GTG   ATA TGG  CGC  ATT  TAC   TAA  
Explanation:
As per the complementary base pairing rule of DNA
C pairs with G and vice versa
A pairs with T (in DNA) or U (in RNA)
Breaking the given strand into triplets, we get - 
TAC  AAA  CAC  TAT  ACC  GCG  TAA  ATG  ATT
ATG  TTT   GTG   ATA TGG  CGC  ATT  TAC   TAA
