The protein encoded by the mutant allele is shorter than the one encoded by the normal allele, the protein encoded by the mutant allele could be non-functional and the mutant allele could be associated with disease. In addition, DNA and mutation can happen possibly wherever on these molecules at any time. The most severe variations take place in the useful units of DNA is the genes in which the mutated form of a gene is named a mutant allele.

Decomposers are very important in our ecosystem, they are responsible for breaking down decaying bodies to transform into nutrients. Without decomposers, plants will not be able to get enough nutrients that it needs to grow
Answer:
They have a gizzard to grind the food.
Explanation:
Birds cannot chew since they have no teeth. However, the beak allows them to split very large seeds or swallow them directly.
For their digestion they have a stomach where digestion enzymes are released. Also they have a gizzard that is an organ that grinds the food mechanically. This gizzard usually has small stones inside that were previously ingested and that helps to digest the food.
