Terrestrial biodiversity is up to 25 times greater than ocean biodiversity. Although a recent discovered method put the total number of species on Earth at 8.7 million of which 2.1 million were estimated to live in the ocean, however this estimate seems to under-represent diversity of microorganisms.
Debenture Bonds. A debenture bond represents money a company has borrowed from the general public, who become creditors of the company.

Hydrogen bonding is a strong dipole-dipole attraction that forms between molecules in which hydrogen is bonded to one of the electronegative elements nitrogen, oxygen and fluo â¦ rine. (dipole-dipole bonds are bonds between dipoles-a molecule that has two oppositely charged poles or ends).luorine, oxygen, nitrogen and carbon only. The first three are very electronegative elements bond with hydrogen to form hydrogen bonding. Carbon can also participate in hyd â¦ rogen bonding, especially when the carbon atom is bound to several electronegative atoms, as is the case in fluoroform, CHF3.
