Answer:
Land restoration can include the process of cleaning up and rehabilitating a site that has sustained environmental degradation, such as those by natural cause (desertification) and those caused by human activity (strip mining), to restore that area back to its natural state as a wildlife home and balanced habitat.
Explanation:
- setting up reliable water provisioning (e.g. by digging wells or placing long-distance water pipes)
- stabilizing and fixating the soil

Answer:
During the Cambrian explosion approximately 535 to 525 million years ago, 2. animals rapidly diversified in the oceans
Explanation:
Scientists have the theory that the Cambiran explosion, approximately 535 to 525 million years ago, <em>was possible because of complex predator-prey relationships and increased atmospheric oxygen levels.</em> All this situation promoted animal diversification. Thinking about evolution, animals directly evolved from protists.
<h3><u>Answer and explanation;</u></h3>
- This can be done by<u> DNA sequencing which is the process of determining the accurate order of nucleotides within a DNA molecule</u>.
- By doing a DNA sequencing for the two sequences of DNA from the two species it will help compare the number of random mutations which have occurred in a molecular clock in the two species - that is, seeing how different the sequences are.
- This will make it possible to infer how long ago the species diverged.
Species A: GTTGAGCTAGTATGGACC
Species B: GATAAGCTAGTAAGGTCA
These species differ in 5 nucleotides.
This number should be multiplied by the rate of mutations; that is;
5 × 15 million years =75 million years.
I don’t understand the question! context?
