Answer:
They tunnel through the soil, which allows air to enter.
Explanation:
Earthworms are considered to be agriculturally friendly living organisms that hold immense importance in improving the growth and productivity of plants.
They live in the soil and feed on the debris of plants such as manure, grasses, roots and dead leaves. They extensively channel and tunnel through soils while moving that causes loosening of the soil resulting in more aeration of the soil. The more the soil aeration is, the better soil drainage is.
Studies have shown that soil containing earthworms have ten times better drainage than soils that donot have earthworms. Therefore, C is the best option.

No a rock is not that strong
Answer:
The correct answer is - A covalent bond between a phosphate group and two 5-carbon ring carbohydrates over two ester bonds.
Explanation:
A bond between a 5 carbon sugar and a phosphate group makes the sugar-phosphate-sugar backbone in nucleic acids. A diester bond links two different nucleotides together to form a polynucleotide.
These are the strong covalent bonds that links a 3' carbon atom of one sugar molecule and the 5' carbon atom of another in deoxyribose sugar in DNA and ribose sugar in RNA.
