Answer:

Circulatory and Longitudinal

Explanation:

The earthworm composed of two sets of muscles which are circular and longitudinal muscles. Circular muscles are thin layers of muscles located beneath the skin and they run around the earthworm’s body. Under the circular muscles is a thicker layer of longitudinal muscles which run from anterior end to posterior end of the earthworm's body. The earthworm becomes longer and thinner on contraction of the circular muscles and when the longitudinal muscles contract the worm becomes shorter and fatter. Therefore, on alternate contracting and expanding of muscles, the earthworm moves.

Watson and Crick's model explained mutability because bases pairs can suffer changes (mutations) during DNA replication. Moreover, this model also explained stability because DNA strands are held together by hydrogen bonds.

Deoxyribonucleic acid (DNA) is a double helix molecule composed of two long chains of four types of nucleotides, each containing one different nitrogenous base, i.e., Adenine, Guanine, Cytosine and Thymine.

In Watson and Crick's model, both DNA strands are held together by hydrogen bonds between nitrogenous bases on opposite DNA strands, thereby providing stability to the DNA molecule.

In DNA, Guanine always pairs with Cytosine by three hydrogen bonds, while Adenine always pairs with Thymine by two hydrogen bonds.

Moreover, Watson and Crick suggested that mutations could occur as a consequence of a base occurring very infrequently in one of the less likely tautomeric forms during DNA replication, thereby also explaining the mutability of life.
