Answer:
The evolution of the species might occur due to the change in the environmental conditions and the mutation in the organisms. The organism that can adapt in the environment will survive better.
The lizard species is present in the Ethiopian biogeographical region but now its two living species is in Neotropical biogeographic region and three species is in Australian biogeographic region. This might possible due to the fact that Neotropical and Australian lineages might have the common ancestor that were earlier originated in the Ethiopian region. The continental drift might have occur that breaks the Ethiopian biogeographical region and the species are present in the different island.
Point is a direct source of pollution. Landfills, gasoline, and chemical plants would be examples of point source pollution. Non-point can be vehicles.
So they both pollute, but point comes straight from something. Non-point is pollution going off from something.
How is it possible that phylogenies based on sequences from nuclear genomes and organellar genomes (i.e., chloroplasts and mitochondria) from the same group of species yield phylogenetic trees with different branching orders?
Answer : <span>The genome of the endosymbiont is more closely related to members of the group in which it originally evolved, while the nuclear genome of the engulfing organism has its own evolutionary trajectory.</span>
The answer is; A
In anaphase of meiosis, all the chromosome line in a single track in the metaphase plate. In metaphase I of meiosis I, chromosome line the metaphase plate of the cell in homologous pairs. This is why at the end of telophase in anaphase I, the genetic material of the daughter cells is halved while in mitosis, it remains the same. Meiosis II is usually similar to mitosis.
