A group of freshwater green algae known as charophytes are the most closely related to land plants.
Charophyta is a phylum of freshwater green algae known as charophytes. It is classified as a division, a superdivision, or an unranked clade. The Embryophyta, or terrestrial plants, evolved within Charophyta, possibly from terrestrial unicellular charophytes, with the class Zygnematophyceae as a sister group.

Hydrocarbon fuels can undergo complete combustion or incomplete combustion depending upon the amount of oxygen available.
Complete combustion happens when there is enough air present. Carbon and hydrogen atoms in hydrocarbon fuel combine with oxygen in an exothermic process, producing carbon dioxide and water while emitting energy.
Incomplete combustion occurs when the supply of air or oxygen is inadequate. Water is still generated, but so are carbon monoxide and carbon. There is less energy released than in full combustion.

amino acids can be described as glucogenic and ketogenic explain the differnces between the two and why some can be both
The primary distinction between glucogenic and ketogenic amino acids is that whereas ketogenic amino acids can be turned into acetyl CoA and acetoacetyl CoA, glucogenic amino acids can only be transformed into pyruvate or other glucose precursors.
Upon deamination, gluconeogenic amino acids produce "amphibolic" intermediates that enter the TCA and may either be oxidized to produce carbon dioxide and water or take the opposite route to produce glucose or glycogen. Deamination of ketogenic amino acids results in ketoacidosis, which undergoes the "acetoacetate" stage of oxidation before being converted to water and carbon dioxide. Both glucose and ketone bodies are produced by amino acids that fall under the criteria of being both glucogenic and ketogenic.
