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:
The main difference between acoelomate and coelomate is that acoelomate is an invertebrate that doesn't have a coelom whereas coelomate is an invertebrate that has a true coelom.
A coelom is a fluid-filled body cavity, which is completely lined by the tissues derived from the mesoderm.
Child proof means that its child-approved, meaning that its made safe for children.
