IBDP Biology Question Analysis Topic: Biology - Short Questions
1) State two postulates of Orparin and Haldane with reference to origin of life.
2) Suggest two practices giving one example of each, that help protect rare or threatened species.
1) Oparin and Haldane suggested that chemical processes in an aqueous environment are where life first began. He put out the following hypotheses: The molecules in the aqueous environment form aggregates or coacervates.
While methane provided the hydrocarbon building blocks for the synthesis of organic molecules and oxygen gas was not present, hydrogen gas functioned as a reducing agent.
2) The creation of national parks and sanctuaries can help to safeguard and conserve rare and endangered species.
These species' habitats might be designated as biodiversity hotspots, which would stop poaching and hunting from causing the extinction of these species.
End of analysis. Great!
