The mammalian tail and the human coccyx, the leaves of pitcher plants and cacti, are homologous organs while, the flippers of penguins and dolphins, as well as the shells of turtles and crabs are analogous structures.
<h3>What are homologous organs?</h3>
Homologous organs are those that are similar in structure but operate differently. They resulted from divergent evolution.
Divergent evolution occurs when species are closely connected to the same ancestors but develop similar structures that perform different tasks in different environments.
Analogous Organs are organs from various creatures that, despite their appearance, perform the same function.
In the given case, the mammalian tail and coccyx, as well as the leaves of pitcher plants and cacti, are homologous organs, whereas penguin and dolphin flippers, as well as turtle and crab shells, are analogous structures.
Thus, these are the different instances of homologous and analogous organs.

Physical and chemical changes may be similar because neither can change the number of atoms of each element that are present.
<h3>What do you mean by Physical changes?</h3>
Physical changes may be defined as those changes which appeared physically like color, odor, texture, mass, and density.
Chemical changes may lead to the formation of new chemicals with definite properties. It involves when the chemical identity of any substance may alter.
Therefore, physical and chemical changes may be similar because neither can change the number of atoms of each element that are present.
