Rna interference (rnai) is a mechanism of gene silencing that is mediated by the presence of double-stranded rna. arrange the steps involved in gene silencing by rnai. a-target rna is degradedb-rna-induced silencing complex (risc) binds to short dsrnac-long dsrna is cleaved into short dsrnad-the sense strand is separated from the antisense strand and degraded. e-antisense rna pairs with the target rna

C.; B.; D.; E.; A.

Explanation:

C. Long dsRNA is cleaved into short dsRNA.

B. RNA-induced silencing complex (RISC) binds to short dsRNA.

D. The sense strand is separated from the antisense strand and degraded.

E. Antisense RNA pairs with the target RNA.

A. Target RNA is degraded.

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.

sorry, is there a picture? i do not see any arrows.
