Why do the polypeptides made in prokaryotes always contain formyl methionine as the first amino acid? The terminator tRNA adds formyl methionine first.
The terminator tRNA adds methionine amino acid first.
The initiator tRNA adds formyl methionine first.
The initiator tRNA adds methionine amino acid first.

the answer is "a.) well–developed vascular system."

explanation:

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.

d. cellulose and starch
