Answer: A substitution mutation can be defined as a mutation in which a single nucleotide is replaced by the other. As a single nucleotide changes in this process which does not create an effect on the final protein so it is a least dangerous type of DNA mutation.
Explanation:
There are three types of substitution mutation:
1. Silent mutation: In this the replaced single base pair gets replaced by the mutated RNA sequence producing the same amino acid. If the nucleotide composition gets changed it will produce the same amino acid.
2. Missense mutation: The nucleotide composition gets changed as a result of addition of different amino acid after mutation in the protein.
3. A nonsense mutation involves the change in the stop codon. This results in non-functioning of the protein.

This causes a net force on the object acting upwards. ... So, for objects that weigh less, per unit of volume than water, the buoyancy force will cause the object to float. For objects that weigh more, per unit of volume (i.e: are more dense) the buoyancy force can't quite win out and the object will sink.
