Answer:
anaerobic organisms do not require the presence of oxygen to produce energy in form of ATP, while aerobic organisms require oxygen
Explanation:
Anaerobic organisms produce energy by glycolysis, which is a metabolic pathway that produces ATP by transforming glucose to lactate when oxygen (O2) is limited. Glycolysis produces two (2) molecules of ATP per glucose molecule. Moreover, when O2 is available, aerobic organisms produce ATP by cellular respiration, which includes glycolysis, the Krebs cycle, and oxidative phosphorylation. Cellular respiration is able to produce thirty-eight (38) molecules of ATP per glucose molecule, thereby being more efficient than glycolysis.
The age is about 4.6 billion years! It varies from planet to planet by a few decimal points, but they all round to the same number
Explanation:
Compounds are those substances that are made up of elements that are combined in a fixed proportion or ratio. The individual property of element is lost once it forms a compound. The physical and chemical properties of both compound and an element is different.
Example of a compound is water and its elements are hydrogen and oxygen. Water is a colorless liquid that acts as a solvent and dissolves most of the solutes in it. While oxygen and hydrogen occurs as gases in their elemental state.
It depends on the species and its primary threats, there is no universal solution. Many South East Asian species are primarily threatened by poaching ("Empty forest syndrome"), whereas many "reptiles" and amphibians from Madagascar can apparently cope with fairly high levels of collection (e.g. Golden Mantella [Mantella aurantiaca]), while the loss of their often small habitat is the primary threat.
