The diagram shows the leg bones of a (left -> right): orangutan, dog, pig, cow, tapir, and horse. most of the animals have the same bones, although some are shaped differently and placed in different positions.

what does this suggest about mammals?
a) that they shared a common ancestor.
b) that mammals are evolving to become more and more like one another.
c) that they all continue to use these structures for the same exact purpose.
eliminate
d) that the shape of the bones has less to do with the environment pressures on the animal and more to do with what their relatives are.

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

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."

ya the other dude is right
