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. When issuing bonds, a company promises to repay the principal amount it borrows on an agreed-to date, and at a particular rate of interest paid at specified intervals.ebenture Bonds.

The two polynucleotide chains that comprise each molecule of deoxyribonucleic acid, or DNA, are held together by two forces: hydrogen bonding and hydrostatic forces. Hydrogen bonds form between complementary base pairs, while hydrostatic forces determine the orientation of the hydrophilic phosphate backbone relative to the more hydrophobic base pairs. Each polynucleotide chain is comprised of a negatively charged phosphate backbone that connects a sequence of base pairs.
