Explanation:
Two techniques that are used in order to restore the biodiversity are the sawing of native seeds or planting individual plants, and the reintroduction of animal species native to the ecosystem.
The restoration of the biodiversity is practically trying to get an ecosystem in its initial, pre-destruction condition, and help it function without any human assistance after certain amount of time.
All restorations of the biodiversity are hard and take time, and there's no guarantee that the outcome will be as planned and wanted. Initially, there the sawing of native seeds and planting individual plants, which is crucial as the plants are the basis of the ecosystems. After that animal species are introduced, small and large, herbivores, omnivores, and carnivores. The people initially have to assist the functioning of the ecosystem, but the idea is to make it function properly over time on its own.

During DNA Replication, the DNA molecule unzips itself so that there are two free strands of DNA. Both of those strands then create new complementary strands of DNA. Thus every subsequent generation of DNA uses one of the parent cell's strand of DNA as a template, which is why DNA replication is said to be semi-conservative. Hope this helped!
