Trawling refers to the process of fishing that uses a fishing net through the sea water behind one or more boats. It is a common method of extraction of sea living resources.

It is the main cause of the degradation of the seabed which threatens the biodiversity. It kills a number of corals, sponges, fishes and the microflora on the seabed. Corals, particularly are damaged wouding the tissue and making them susceptible to infection. It also removes certain economically important sea weeds. The ocean sediments are disturbed causing the suspended solids to enter the seawater and causing turbidity affecting the penetration of sunlight. The suspended soilds can also cause growth of harmful algae causing algal blooms affecting the other biotic factors of the sea. The disturbance in the ocean sediments due to trawling causes the harmful pollutants like DDT that are trapped in the sediments reach the water column and enter the food chain of the living organisms.

Two nucleotides on the same strand form a __________ bond while two complimentary bases on opposite strands form ____________ bo
Anna [14]

Two nucleotides on the same strand form a <u>Phosphodiester bond </u>while two complimentary bases on opposite strands form <u>Hydrogen bonds</u>. An a-t base pairing forms <u>2</u> such bonds.

The constituent components that make up DNA's double-helix structure are known as nucleotides. Each nucleotide has a base in it. The four various colors you see here stand for the four different bases that might be used. Between nucleotides, a unique kind of covalent link known as a phosphodiester bond occurs. The two strands of DNA are formed by these phosphodiester linkages.

Hydrogen bonds are the bonds that develop between base pairs. Thymine and adenine make two hydrogen bonds, and guanine and cytosine form three hydrogen bonds. Therefore, we have concluded that hydrogen bonds are the type of binding that develops between base pairs in DNA to hold the two strands of a double helix together.
