reproductive isolation: the gene pools of two populations must become separated for them to become new species. As new species evolve, populations become reproductively isolated from each other.
Many species never change over long periods of time because the environment stays the same. If the environment changes, the species has to change or it will die out. They must adapt to these changes.
Genetic divergence between subpopulations within the ancestral species.
Reproductive isolation
Some species are becoming extinct. It is due to various environmental factors. Deforestation, ozone depletion are some.
The weak die off before they can reproduce.
Yeasts are unicellular organisms. Some species with yeast forms may become multicellular through the formation of strings with connected budding.
diamond is formed from carbon. Some diamonds include other trace minerals, but they are not necessary in the formation of diamond.
Some of the biotic factors would be rainforests where they live and humans that have hunted them. Some abiotic factors would be rainfall, temperature, water, and bones and hair for food. The Tasmanian devil is an endangered species.
Climate, silent and sanitary environment, and enough food for the worms are some critical factors that affect the cocoon formation.
temperature and pressure
some factors that determine the number of species in an area. some factors that determine the number of species in an area.
Ionization energy, luttice energy, force of attraction between posetively and negatively charged ions are some of the factors that affect the formation of ionic compounds.
As far as DNA and RNA, nitrogen is an absolutely necessary part of their formation.
There are several important factors necessary to successful replantation, including special instrumentation and transportation of the amputated finger.
i dont know ,plz some one give the answer

To some, its tells us how animals and plants came to be what they are, and how they were and how mutations led to the formation of new species.
A species that "belongs" in a particular area, as you put it, is called a native species. I am sure that animals who find themselves in a non-natural habitat are called a non-native species, an invasive species, or introduced species. The introduction of some species into new environments can have devastating results - this is because the invasive species can eradicate necessary native species that are necessary to support a healthy ecosystem.
The weak die off before they can reproduce.
There are many factors that influenced the formation of a code of ethics within real estate. The main factor was to bring some sanity and have a reference point when conducting business of buying, selling or leasing property.
