Exploring molecular, genetic and species-level diversity for products of economic importance is called:

Genetic diversity is the measure of

In the species-area relationship equation $\log S = \log C + Z \log A$,what does $Z$ represent?

How many species in the world are facing the threat of extinction according to the $IUCN$ Red List $(2004)$?

Which of the following represent the maximum number of species among global biodiversity?

Initially $A$ biodiversity hot spots were identified but subsequently nine more have been added to the list,bringing the total number of biodiversity hot spots in the world to $B$. These hot spots are the regions of accelerated habitat loss. Three of these hot spots—Western Ghats and Sri Lanka,Indo-Burma,and Himalaya—cover our country's exceptionally high biodiversity regions. Although all the biodiversity hot spots put together cover less than $C$ $\%$ of the earth's land area,the number of species they collectively harbour is extremely high,and the strict protection of these hot spots could reduce the ongoing mass extinctions by almost $D$ $\%$. $A, B, C$ and $D$ in the paragraph refer to:
