What environmental factors cause mutations?
Mutagens are chemical or physical factors that increase the rate of mutation. Some are natural, and some are synthetic.
Some examples of mutagens are:
- Cosmic rays
- Some viruses
- Harmful atomic radiation
- Recreational drugs

As the amount of hydrogen ions in the soil increases the soil pH decreases thus becoming more acidic.
Carcinogenic pollutants, and ultra-violet radiation
External influences can create mutations. Radioactive sign Mutations can also be caused by exposure to specific chemicals or radiation. These agents cause the.
The general term for an environmental factor that causes a population to decrease is a limiting factor. Some examples are emigration and mortality, a lack of resources, na…tural disasters happen which makes people scared to to live there so the people flee, and habitat loss.
It is called evolution, and the key to evolution is mutations, which happen naturally in the environment, and not by force. Short Answer is Pollution.
the presence of hot fluids causes the mineral crystals to become extremely large.
The environmental factors are caused by coming into contact with magma. When magma moves through the crust, it heats the surrounding rock and "cooks" it.
It is called a limiting factor.
The Sun's high-energy rays, like ultra-violet light, cosmic or gamma rays, and so forth can cause mutations. Harmful chemicals in the bloodstream may cause mutations, as well.… Fortunately the atmosphere shields us from the worst ultraviolet light, and the Van Allen belt above that filters out cosmic rays and/or gamma rays, except around the north pole and south pole. The northern lights and southern lights are a result of these high-energy rays hitting the high atmospheric layers.
It increases the odds of mutation.
A mutation is a change in a species over time and mutations are random among different animals and are chosen by natural selection
exposure to toxic chemicals
Mutations can occur from endogenous or exogenous factors or from errors. Translocation, insertion and deletion are examples of factors that cause genetic mutations.
Mutation are sudden heritable changes which give rise to new alternative form of genes i.e gives rise to a new novel phenotype which is somewhat different from genetic recombi…nation. Mutation can be sponataneous or induced . 1. Spontaneous mutation are those which occur in the absence of a exogeneous substance often called as mutagen causes of spontaneous mutation are error in Dna replication,transposition,spontaneous lesions(deamination). 2.Induced mutation are one which are the result of exogeneous substance called mutagen such as ionic radiations,intercalltaing agent,oxidizing agents etc.
Some of the things which may provoke a reaction include surgery, especially gastrointestinal surgery; a change to a low fat diet, which has an increased number of wheat-based …foods; pregnancy; childbirth; severe emotional stress ; or a viral infection.
