They are seen under the surface of the land or the water, there are petroleum reservoirs. Utilizing enormous drilling equipment, their crude oil is extracted.
Note that Over the course of millions of years, when the bones of dead animals and plants settle to the ocean floor, gas and oil are formed in the sea. They are buried and crushed into layers of sediment several kilometers deep on the ocean floor when combined with particles discharged from the land.

Explanation:
Acrostic of "naturalist"
Naturally you want to keep every thing in his being,
a cynic is a man who knows the price of everything and gives no value to anything,
talk much to say nothing,
under your feet a hawk wing.
Rarely occurring,
a dead crowned his only nothing,
later soft and groups passing,
i am the son of nowhere or a king.
Satellite you, I do not do anything,
take your cross singing and not sighing.

DNA replication begins when the double helix untwists and breaks in half between the nitrogen bases. What are the next two steps in the process of DNA replication?
Answer:
Step 1: Before DNA can be replicated, the double stranded molecule must be “unzipped” into two single strands. ... Step 2: Primer Binding. The leading strand is the simplest to replicate. ... Step 3: Elongation. ... Step 4: Termination
The DNA gets unzipped during DNA replication after the double helix unwinds. Each original DNA strand acts as a template for the new strands when the strands are split in two. The bases on either half of DNA are then paired with the nitrogen bases that have sugar and phosphate. In order to adhere to the principle of base pairing and guarantee that the base sequence is maintained, the molecules present in the new strand must be complementary to those found in the original strand. DNA replication ends with the formation of two identical strands.
