<span>Conservation strategies that set aside ecosystems for preservation </span>are the best way to preserve an area's diversity.
The World Wildlife Fund says that the conservation strategies that focus on ecosystems for preservation have an impact on preserving and area's diversity because it is a complete, healthy ecosystem, filled with all that is part of it, that will maintain the diversity of its area - for example, if a species of a tree from a certain ecosystem was to be extinct, not only that species would disappear, reducing already by itself the diversity of the area, but it would also affect other species taking them probably also to eventual extinction, once more reducing the diversity of the area.
The correct answer is D. Precambrian Time - Paleozoic Era - Mesozoic Era - Cenozoic Era. This is the correct order of the geologic time scale, from oldest to most recent. Thank you for posting your question. I hope this answer helped you. Let me know if you need more help.
The evolution of sexual reproduction is a great puzzle in modern evolutionary biology. Many groups of eukaryotic organisms, especially most animals and plants, reproduce sexually. The evolution of sex between two organisms of the same species contains two related but different themes: its origin and its maintenance. However, since hypotheses for the origin of sex are difficult to test experimentally, most of the current work has focused on the maintenance of sexual reproduction. Biologists, including W. D. Hamilton, Alexei Kondrashov, and George C. Williams, have proposed various explanations for how sexual reproduction is maintained in a large set of different living things.
That would be a Chloroplast
There numerous of them but some of them would be contaminated soil which can be followed with altered soil chemistry that contains fewer soil organisms that are essential. The third one would be surface runoff due to extensively modified hydrology of the area.
