Explanation:
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.
Hi! I would describe this component in my own words by saying component is flexibility by saying that the three components of flexibility are muscle elasticity and length, joint structure and nervous system. Yes, these components of fitness are very important as they help us do the things in our daily lives. I would say the nerve system is more important than the rest with the joint structure coming in second place. We need the nervous system because they they transfer nerve impulses between the parts of our body. I hope this is what you were looking for, Goodluck!
