What is the main factor that leads to speciation between two populations?
Lack of exchange of genetic information.
What are the main steps of photosynthesis?
There are two main steps. They are dark reaction and light reaction.
Which is a part of the two process of speciation?
Speciation occurs through two main processes: allopatric speciation and sympatric speciation. Allopatric speciation happens when populations are geographically separated, leading to reproductive isolation and divergent evolution. In contrast, sympatric speciation occurs within the same geographic area, often due to behavioral changes, ecological niches, or genetic mutations that lead to reproductive barriers. Both processes result in the formation of new species through mechanisms that reduce gene flow between populations.
What are the two main types of isolation?
That would be geographic isolation and reproductive isolation. Both could lead to speciation.
What are three events that can lead to speciation?
Species (phylogenetically and genetically distinct animals from a common ancestor) form when barriers exist to prevent outbreeding. These are usually environmental (e.g. mountain ranges, oceans, climatic barriers) or biological (e.g. interbreeding of two species results in an infertile offspring).
What is one of the main causes of speciation?
geographic isolation and the reduction of gene flow
When speciation complete?
When the two populations can no longer interbreed.
What are the two phases of speciation?
The two phases of speciation are allopatric speciation and sympatric speciation. Allopatric speciation occurs when populations are geographically isolated, leading to genetic divergence due to natural selection, mutation, and genetic drift. In contrast, sympatric speciation happens within the same geographic area, often through mechanisms such as polyploidy in plants or behavioral changes in animals that reduce gene flow. Both processes ultimately result in the formation of new species.
What two main steps used to treat water from reservoirs?

What is thought to be the two factors demonstrating sympatric speciation in the cichlids of Lake Victoria in East Africa?
-rapid speciation -sexual selection
Two main steps for building proteins from genetic information are?
transcrption and translation
What are the steps of organic evolution?
Organic evolution involves four main steps: variation in a population due to genetic mutations or recombination, natural selection where certain variations are favored based on their fitness, adaptation leading to changes in a population over time, and speciation where new species arise due to accumulated changes.
