A maybe sounds abt right sorry if it's wrong.
The total number of base pairs is equal to the number of nucleotides in one of the strands (each nucleotide consists of a base pair, a deoxyribose sugar, and a phosphate group).
Answer: The hydrophilic tails are directed inward and the hydrophobic heads are directed outwards.
Explanation:
A phospholipid is made up of two ends a hydrophilic or water-loving end that is phosphate head and a hydrophobic tail that is made up of fatty acid tail. The arrangement of phospholipid in a bilayer structure allows the entry of oxygen, carbon dioxide, and lipids to pass through them via concentration gradient via simple diffusion.
