The term protobiogenesis used for theory of:
1 Panspermia
2 Special creation
3 Biochemical origin of life
4 Spontaneous generation
Explanation:
The term protobiogenesis used for theory of biochemical origin of life or Oparin Haldane theory of protobiogenesis. Protobiogenesis refers to origin of first life form from non-living chemical assemblages.

Pasteurs experiment to refute the theory of spontaneous generation was successful spontaneous generation did not occur in his set up because
1 he did not boil the flask for long
2 the S-shaped flask used by Pasteur prevented the contamination of broth by air
3 extreme precautions were used by him to kept his flask covered
4 he used muslin cloths to cover his experimental set up.
Explanation:
Pasteurs experiment to refute the theory of spontaneous generation was successful spontaneous generation did not occur in his set up because extreme precautions were used by him to kept his flask covered. He succeeded in disaproving the spontaneous generation theory because the swan neck of the flask allowed only air, and not the microbes.

Evolution is:
1 Progressive development of a race
2 History and development of race along with variations
3 history of race
4 development of race
Explanation:
Evolution is the change in the characteristics of a species over several generation and relies on the process of natural selection. It is the biological change of a species over a span a time for example. bluemoon butterfly, Dormouse and Mexican cavefish etc.

The presence of gill slits, in the embryos of all vertebrates, supports the theory of:
1 metamorphosis
2 biogenesis
3 organic evolution
4 recapitulation
Explanation:
The presence of gill slits, in the embryos of all vertebrates, supports the theory of recapitulation. Recapitulation theory, stated as the biogenetic law by E.H. Haeckel, that the embryological development of the individual repeats the stages in the evolutionary development of the species.
