Which of the following structures are 'homologous' from the evolutionary point of view?
1 Petals of rose and the anther of an apple blossom.
2 Thorn of bougainvillea and tendrils of cucurbita
3 Spines of a cactus and spines of a porcupine.
4 Flagellum of Euglena and the flagella of Paramecium
Explanation:
Both Flagellum of Euglena and the cilium of Paramecium are similar infunction (locomotion) and are Analogous to each other.

Read the statements A and statement B carefully to mark the correct options given below. Statement A : All vertebrates develop a row of vestigial gill slits during embryonic stage. Statement B : Embryos always pass through the adult stages of other animals.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
Explanation:
Embryological support for evolution was proposed by Ernst Heckel. It is based upon the observation of certain features during embryonic stage common to all vertebrates that are absent in adult. For example, the embryos of all vertebrates including human develop a row of vestigial gill slit just behind the head but it is a functional organ only in fish and not found in any other adult vertebrates. However, this proposal was disapproved on careful study performed by Karl Ernst von Baer. He noted that embryos never pass through the adult stages of other animals.

Fossils are generally found in
1 Sedimentary rocks
2 Igneous rocks
3 Metamorphic rocks
4 Any type of rock
Explanation:
Fossils are generally found in sedimentary rocks, which are formed by the gradual deposition of slit, sand or calcium carbonate over millions of years in regions such as lakes or sea during their formation, the dead animals are carried to the sea or large lake, sink down and get buried in the rocks and converted into fossils.
