Answer:
Harmful mutations may cause genetic disorders or cancer. A genetic disorder is a disease caused by a mutation in one or a few genes. A human example is cystic fibrosis. A mutation in a single gene causes the body to produce thick, sticky mucus that clogs the lungs and blocks ducts in digestive organs.
Mutations arise spontaneously at low frequency owing to the chemical instability of purine and pyrimidine bases and to errors during DNA replication. Natural exposure of an organism to certain environmental factors, such as ultraviolet light and chemical carcinogens (e.g., aflatoxin B1), also can cause mutations.
only a small percentage of mutations cause genetic disorders—most have no impact on health or development. For example, some mutations alter a gene's DNA sequence but do not change the function of the protein made by the gene.
<span>Well the Dutch were the 1st country to recognize the colonies and being a major seafaring trader helped keep a starved and under supplied colonial army from late 1776 on,the French as a nation sold weapons and granted loans and towards the end landed an army used their fleet to run off the british and trapped Cornwallis at Yorktown,French citizens also volunteered to train the American army ,most notably LaFayette but there were many.Those are the only ones i know of but you have to understand that the world didn't exist as it did today their wasn't anything over here as far as nations that could assist and European nations were the only ones who could really be expected to have any interest so having French and Dutch assistance to of the biggest powers in Europe was really pretty good</span>
