Explanation:
Solids:
Particles stay close together with a pattern
Particles do not flow freely
Definite shape and definite volume
Liquids:
Particles are closer together (compared to gas) with somewhat of a pattern
Particles flow freely
Somewhat strong attractive forces that hold an indefinite shape
Gas:
Particles spread out without a pattern
Particles flow everywhere (they are like kids on a sugar rush)
Weak attractive forces that hold no shape or volume
Indefinite shape and indefinite volume
Not entirely sure what compressibility is so i skipped that one for all of them

Answer:
Equal amounts of DNA contain equal proportions of nitrogenous bases.
Explanation:
According to Chargaff's rule, the nitrogenous base pairs (Purines and pyrimidines) have an equal ratio (1:1) in the DNA of all the organisms. More precisely, the amount of adenine is equal to thymine and the amount of guanine is equal to cytosine in the DNA of all the organism. A-T base pair has two H-bonds while G-C base pair has three H-bonds.
