Which of these pairs of body structures best illustrates a homologous relationship? a) the leg of a horse and the leg of a dog
b) the wing of a bat and the wing of a bird
c) the fin of a dolphin and the fin of a shark
d) the beak of a bird and the beak of a turtle

The correct answer would be A) the leg of a horse and the leg of a dog.

Homologous organs refer to the set of organs which are similar in their structure but performs different functions as a result of adaptation towards different environments.

These organs are the result of divergent evolution.

For example, human arm, horse leg, dog's leg, the wing of a bird, and the flipper of a dolphin or whale are formed from the same set of bones and but perform different functions and thus, they are the homologous organs.

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.

a metamorphic rock would be formed.
