Answer: The change in the structure of the genes or change in the DNA sequence is called mutation. The mutations are of different types that are deletion, rearrangement, insertion and others.
Explanation:
Mutation in which the one to several nucleotides get changed at a point is called point mutation. The point mutation can be in the form of deletion, substitution, and insertion. Deletion will involve the removal of nucleotide that involves the change in the sequence of DNA. When the nucleotide is added to the genome it is called insertion. In deletion and insertion the whole sequence of nucleotides from the point of mutation get displaced this affect the codons in the amino acid sequence which is responsible for protein synthesis so the functioning of the body may get affected by such mutations.
In the case of substitution the new nucleotides are added to the DNA sequence and the one which was already present at that place is removed. So, only one amino acid in the sequence will change so the polypeptide structure will not be affected.
Answer: the jelly has an awful taste, which protects the eggs from predators until they are ready to hatch
One reason ecosystem stability is important for life-forms because it creates a habitable environment for life-forms to live in. Such stability is important for an adjoining one because it allows the sphere of influence and boundaries to extend beyond its boundaries. This results in impacting changes to adjoining ecosystems. I hope that this is the answer that you were looking for and it has helped you.
The bear population would increase. The bears would have enough food to support more cubs/bears.
Evolution is what you might call, traits that is inherited over generation to the next. An evolution is when there is a change within the genepool and it beneficial to survival. Take a giraffe for example. Back then, they had short necks and it had eat from plants on the ground. Though from generations later when they learnt that food grows on trees and stretched there necks to reach for, they now can eat from trees without a problem. Hope this helps you better understand what evolution is.
