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.
1. Medium-range training involves periods of 10 to 30 minutes of high-intensity exercise at
90 to 100 percent TI. This training is a type of “racing” workout. LSD training is an activity
that’s performed at a low intensity and can be sustained indefinitely. It teaches the body
to burn fat and creates endurance. LSD training should exceed 30 minutes.
2. The starter phase allows the body to get used to the idea of exercise and to avoid soreness
and injury, and it allows individuals time to experiment until they find the program
that works best for them.
I believe it would be unrealistic goals, because then you would be pushing yourself harder when your body shouldnt be working that hard.
