Answer:
Gas from Earth's core came to the surface through volcanoes.
Recent hypotheses about the origin of organic molecules suggest that these molecules may have formed in hydrothermal vents deep in the oceans, where hot gases and elements emerge from cracks in Earth's crust.

After the orginal trand has been seperated in DNA replication, the tRNA's bring together an amino acid, strands wind tightly together -corresponding base pairs are laid, and lastly, the bases are proofread for any errors.
The attached diagram illustrates the answer in detail. As
indicated, in the diagram, the phases of the moon do not change over moonrise and
moonset, because of both the earth and
moon orbit the sun together. These phases are what
we observe due to the angles of the refection, to earth, of the sun rays by the moon
(based on its position in respect to the
earth and sun).
The phase of the moon influences moonrise and moonset. This
is due to the relative position, with each other, of the 3 celestial bodies (moon,
earth and sun). The second table shows the times for moonrise and mooset with each phase.
Human egg cell
But human egg cell is the one of the largest cells in the human body that can be seen with naked eye. i.e we are able to see it without the help of a magnification device. The size of this cell is about 0.12 mm in diameter.
