Which cell structure is mainly responsible for releasing energy from food molecules in some single-celled organisms? A) The mitochondria produce enzymes, and ribosomes transport them. (:

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."
