IV-Keystone hypothesis
V-Idiosyncratic hypothesis
a) Species that play the same roles in a community can compensate for each other if some are lost under particular conditions
b) Community services change as the number of species increases or decreases
c) there is a linear correlation between species richness and community services
d) species is an organism that helps hold the system together
e)Some species play a small but critical role in keeping the plane

During the biosynthesis of brassinosteroid derived from the sterol campesterol follows two types of the pathway
i) Late C-6 oxidation pathway
ii) Early C-6 oxidation pathway
follows  the different reaction performing in each  pathways such as,
a) Campesterol → Campestanol →6-Deoxoteasterone→ Castasterone→Teasterone →Brassinolide
b) Campesterol → 6-Oxocampestanol →Cathasterone →Teasterone → Castasterone →Brassinolide
c) Campesterol → Campestanol →6-Deoxocathasterone →6-Deoxoteasterone → Castasterone →Brassinolide
Find the correct combination of the each oxidation pathway with its performing sequences;
