The mammalian tail and
cluponka [151]

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.

dimaraw [331]

Answer:

The answer is rough endoplasmic reticulum.

Explanation:

Because it has a complex structure made up of membrane and ribosomes and it produces only a limited number of proteins just like the very efficient conveyor belt that produces only a few products.

I hope this answer helps.
