The images show the wings of two different organisms. the wings of the housefly and the bat are this indicates that

First answer is Analogous Structures.

Second should be Their wings don't share a common evolutionary lineage.

The wing of housefly and bat have the same function but and anatomically different, such structures are called analogous structures. Since they do not share any common ancestor their internal anatomy is different though they perform same function.

Homologous structure in turn are those which have same internal anatomy, share a common ancestor but perform different function.

In this case, the wings of the housefly and bat are analogous structure. This indicates that they don't share common ancestor.

glacial erosion, the picking up and movement of earth beneath a glacier, is also referred to as plucking. erosion and transportation of individual pieces of bedrock, especially large "joint block occur as a result of this glacial erosion. plucking is type of erosion in which rocks become frozen into the bottom and sides of the glacier.as the glacier moves downhill it 'plucks' the rocks frozen into the glacier from the ground.
