DNA replication only happens during meiosis because the chromosome number of the species remains the same from one generation to the next, the chromosome number of germ cells must be reduced by half during meiosis. To achieve this feat, meiosis, unlike mitosis involves a single round of DNA replication followed by two rounds of cell division.
Region A, Hope this helps.

Biodiversity hotspots are the richest and most threatened reservoirs of life on Earth. Thus, the correct option is D.
<h3>What are Biodiversity hotspots?</h3>
Biodiversity hotspots may be defined as the regions of the earth which are rich in biodiversity and possesses the following criteria:
- The area should support greater than 1500 endemic species of flowering plants or 0.5% of total plants.
- It possesses a high degree of threat, exploitation, and biodiversity.
- It must have lost about 70% of the original habitat.
- A high degree of endemism (restricted habitat).
Therefore, Biodiversity hotspots are the richest and most threatened reservoirs of life on Earth. Thus, the correct option is D.
