Answer:
The correct answer will be option-true.
Explanation:
Biodiversity hotspots are the regions which can be identified by a high level of endemism and high level of habitat loss. The concept of the hotspot was given by the British ecologist Norman Myers in 1988 when he observed such areas.
Since a region to be established as a biological hotspot fulfils two criteria:
1. Area should have at least 1500 unique vascular plant species found nowhere on Earth
2. Should have lost at least 70% of its native vegetation
Therefore, a scientist identity a hotspot by counting a number of endemic species and option-true is the correct answer.

Explanation:
<span>When Prophase is occur, during this stage, changes occur both in the cytoplasm and in the nucleus. Within the nucleus, the chromatin fibers become more tightly coiled and folded, forming discrete chromosomes that can be seen with the light microscope. The nucleoli disappear. Each duplicated chromosome appears as two sister chromatids joined together, with a narrow waist at the centromere.In the cytoplasm, the mitotic spindle begins to form as microtubules rapidly grow out from the centrosomes which begin to move away from each other.</span>
