I need help ASAP

PLIS

Mouth: Closed. Operculum: Opened. Floor of buccal cavity: Raised

Explanation:

When fish breathe out, the mouth closes and muscles raise the floor of the buccal cavity and push in the walls of the operculum. The opercula opens and water is pushed out over the gills' surface.

Hope this helps. :)

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
