.The Mixture has volume of 24.5L at 260

c.Calculate the partial

pressure of each gas in the mixture and the total pressure of the gas

mixture..( Atomic mass of Ar & Kr are 39.948g/mole,83.79g/mole

respectively molecular mass of CO2 =44g/mole))​

Answer 1

Answer:

The DNA molecule consists of two strands that wind around one another to form a shape known as a double helix. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases--adenine (A), cytosine (C), guanine (G), and thymine (T).
