The Organs which perform same function and looks but they are different in their structure from each other are called as analogous organs. Organs are the structures that made up of two or more tissues organized to carry out a particular function. An organ or bone that appears in different animals with same function is called homologous structure. Homologous organs have similar origin n basic structure but perform different functions in different organisms. Analogous organs are different in basic structure but perform same functions. Different animals have bones that appear very similar in form or function and seem to be related. Examples The arm of a human, the wing of a bird or a bat, the leg of a dog and the flipper of a dolphin or whale are homologous structures. They are different and have a different purpose, but they are similar sharing common traits. The forelimbs of all mammals have the same basic bone structure.The structures are similar because they evolved to do the same job. For example, the wings of bats and birds.
A wedding ring is a common symbol of love and commitment. It is a universal symbol of marriage. The other options are also symbolic, just of other things.
