Answer:
Symbiosis is a close relationship between two species in which at least one species benefits.
Explanation:
Phospholipids are typically made up of two fatty acids,a glycerol molecule and a phosphate group that is modified by an alcohol.The phosphate group is negatively charged, it is hydrophilic and it is describes as the polar HEAD of the phospholipid.

Answer: 20 amino acids
Explanation:
The Genetic code permits the triplet nature of codons whereby three nucleotides from Adenine, Uracil, Guanine and Cytosine on the messenger RNA (mRNA) join to form 64 codons.
Since more than one codon can specify for an amino acid, the 64 codons then specify for 20 amino acids, that then form the sequence of various proteins
