Answer: Ribose nucleotides and the nitrogenous bases
Explanation: RNA consists of ribose nucleotides (nitrogenous bases appended to a ribose sugar) attached by phosphodiester bonds, forming strands of varying lengths. The nitrogenous bases in RNA are adenine, guanine, cytosine, and uracil, which replaces thymine in DNA.
Answer:
Explanation
the two basic difference between RNA and DNA are
RNA is single stranded while DNA is double stranded
RNA contain uracil and DNA contain thymine
Answer:
osmolarity depends upon molarity.
glucose is a non-ionizing substance. it won't break down and will go as a whole.
osmolarity means the solute concentration of a solution.
here, the solvent is water.
therefore, 1 osmole = 1 mol
the ions of glucose after forming a solution (i) = 1
osmolarity = 1.5 M glucose × 1
= 1.5 osmoles of glucose.
In terms of macromolecules, needed and utilized by organisms to carry out essential metabolic chemical reactions and for maintaining structure would be Lipids.
Lipid based molecules or Fats tend to store the most energy, as breaking chemical bonds connecting fatty acid chains of long hydrocarbons releases quite a bit of energy.
