Answer:
Covalent bonds appear inside every linear chain and connect bases, sugars, and phosphate groups.
Hydrogen bonds appear between two strands and involve the base from one strand with the base from another strand in the complementary pairing.
Explanation:
A covalent bond is a chemical bond formed by joining electrons of two non-metal atoms into one or more common pairs.
A hydrogen bond (X-bond) is a type of weak chemical bond based on electrostatic attraction between a hydrogen atom and a nucleophilic atom that contains free electron pairs.
Because animals get sugar from food they eat, they do not need chloroplasts, just mitochondria. Both plants and animal cells have vacuoles. A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. Plant cells have a cell wall, as well as a cell membrane. PRETTY COOL!
