WebSelect the TWO answers that are correct. A.) Adenine is used in RNA, whereas cytosine is used in DNA. B.) Uracil is used in RNA, whereas thymine is used in DNA. C.) RNA has one fatty acid chain, whereas DNA has two of them. D.) RNA contains sugars in its backbone, whereas DNA does not. WebSolution Verified by Toppr Concept: Atoms that have a stable electron configuration, i.e. octet, exist independently. ∙ Two atoms that exist as independent atoms are argon (Ar) and h elium (He). ∙ These are noble gases and have a stable electron configuration. So, they can exist independently.

WebSalt (sodium chloride, NaCl) and soda (sodium carbonate, Na 2 CO 3) had been known since prehistoric times, the former used as a flavouring and preservative, and the latter for glass manufacture. Salt came from seawater, while soda came from the Natron Valley in Egypt or from the ash of certain plants. WebCorrect option is A) Option A is false. Atoms are not able to exist independently. All the elements on the far right side of the periodic table (inert or noble gas) atoms can exist independently because they all fulfil the octet rule. They do not need bond to become stable. Option B is true. Atoms are the basic units from which molecules and ...
