During photosynthesis, the energy from sunlight splits water molecules to produce a chemical reaction. The hydrogen ions from water molecules are participate in the reaction by forming a sugar called glucose (C6H12O6). It can be observed that all of the hydrogen is converted to glucose, while elemental oxygen is produced.
Some neurons have a fatty layer covering called MYELIN SHEATH around their axon. This layer is not continuous and the gaps are called NODES OF RANVIER.
Because the myelin sheath is made up of insulating fatty substances, the nodes of ranvier allow the fast transmission of electrical impulses along the axon.
Answer: Only the single-celled organisms of the domains Bacteria
Explanation: Only the single-celled organisms of the domains Bacteria and Archaea are classified as prokaryotes—pro means before and kary means nucleus. Animals, plants, fungi, and protists are all eukaryotes—eu means true—and are made up of eukaryotic cells.
