Alot, a new discovery is not overexploited
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.
<span>The lipids would be less saturated.</span>They would be less saturated. In order to maintain fluidity at low temperatures, you want your hydrocarbon chains to interact less. Saturated bonds will branch off at angles, decreasing the contact area between the molecules and therefore decreasing intermolecular forces.
The membranes would contain more cholesterol because cholesterol maintains fluidity too.
It would be organic rocks, they are formed from fossils and the hard parts like the shells and bones of various living organisms
