Patterns of distribution change depending on the scale at which they are viewed, from the arrangement of individuals within a small family unit, to patterns within a population, or the distribution of the entire species as a whole (range). Species distribution is not to be confused with dispersal, which is the movement of individuals away from their region of origin or from a population center of high density.

What is the principle for dating materials using radioactive isotopes
It is based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates.
How are isotopes used in radioactive dating?These isotopes decay within the rocks according to their half-life rates, and by choosing the fit minerals and measuring the relative amounts of parent and daughter isotopes in them, the date at which the rock crystallized can be determined.
Thus, It is based on a comparison between the observed abundance of a naturally occurring radioactive isotope.

Explanation:
In the past few years, several bills that deal with noise pollution have been introduced in Congress. Several lawmakers want to make stricter laws at the national level to restrict noise pollution.
Compose a letter to one of your state's representatives about noise pollution. In your letter, persuade your lawmaker that noise pollution should be controlled more strictly and be sure to address the following points:
explain what noise pollution is and where it comes from,
explain how noise pollution can harm people,
explain how noise pollution can harm wildlife, and
explain how you think national noise pollution laws could work.
Answer:
1.Noise pollution, also known as environmental noise or sound pollution, is the propagation of noise with ranging impacts on the activity of human or animal life, most of them harmful to a degree. The source of outdoor noise worldwide is mainly caused by machines, transport, and propagation systems.
2.Noise pollution impacts millions of people on a daily basis. The most common health problem it causes is Noise Induced Hearing Loss (NIHL). Exposure to loud noise can also cause high blood pressure, heart disease, sleep disturbances, and stress. These health problems can affect all age groups, especially children
3.Studies have shown that loud noise can cause caterpillars' hearts to beat faster and bluebirds to have fewer chicks. Noise pollution makes it difficult for animals to use sound for navigation, finding food, mating, and avoiding predators, affecting many animals' ability to survive
4.We can Reduce Noise pollution by turning off appliances when not in use, use of earplugs, lowering the volume, planting more trees, regular maintenance of vehicles and machines. By controlling noise we can control negative health effects that noise pollution has on everyone.
