You look out over a field of sunflowers. a farmer has grown the sunflowers to harvest and sell the seeds. some of the sunflowers are tall; some short. some of the flowers are bright yellow; others more multicolored. some heads are full of seeds; some are not full.

a. to encourage apoptosis

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."

idk im sorry.
