Answer:
Presence of inorganic molecules with lightning and intense radiation
Explanation:
This process of formation of organic molecules from inorganic molecules is called abiogenesis. It is believed that this is how the first organic molecules were created in early earth about 3.8 billion years ago. The classic 1952 Miller–Urey experiment attempted to replicate the condition of early earth. They replicated lightning strikes (using electric parks) in a glass with greenhouse gases believed to have been the major constituents of early earth's atmosphere like methane. They were able to form primitive organic molecules from this experiment.
Answer:
true
Explanation:
Pollen grains help scientists identify plants and make assumptions on past climate conditions. understand tree growth and make assumptions on past climate conditions.
Answer:
Seaweed most commonly inhabit the littoral zone (nearshore waters) and, within that zone, on rocky shores more than on sand or shingle. Seaweed occupy various ecological niches. At the surface they are only wetted by the tops of sea spray, while some species may attach to a substrate several meters deep.
