Why would covalent bonds break in water? Why can they? - Because more stable or energetically favored bonds could be formed. They can break because the loss of energy by breaking hydrogen bonds in compensated for in the formation of new covalent bonds. Limitation to eukaryotic cells and photosynthesis - The sea slugs that live in symbiotic relationships with cyanobacteria or algae. The algae is not broken down or digested and absorbed into the slug's body. There is then a horizontal gene t...
