Dna is a polymer consisting of repeating units known as Necleotides.
It's tendon.
Tendon is a connecting tissue that connects bones and muscles.
All amino acids contain amine (-NH2), carboxyl (-COOH) and R group (side chain) with hydrogen (H).
All of the 20 amino acids coded by genetic code have N-terminus (amine) and C-terminus (carboxyl) and those are called functional groups. The key components of amino acids are hydrogen, oxygen, carbon and nitrogen. They can be classified in different subgroups according to their polarity, the core structural functional groups, side chain group type, pH.
Answer:
The correct answer is Option A. polarity and good solvent.
Explanation:
Polarity is the property of water molecules to make poles. Poles are formed between two atoms having difference in electronegativity values. In water molecules, partial positive charge appears on hydrogen atom and partial negative charge appears on oxygen atom. Water is universal solvent which means it dissolves maximum number of solutes within itself.
