"when viewing the liverworts, make sure you identify the sexual structures and and understand the role they have in the life cycle"

Ensure that you will able to identify the sexual structures antheridia (the male sex organ) and archegonia (the female sex organ) and understand the role they have in the life cycle, when viewing the liverworts. Liverworts can replicate asexually through gemmae cups or fragmentation. (antheridia, archegonia)

uh two lol

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.
