How is crude oil brought to the surface

Biology
1 answer:
natta225 [31]3 years ago
8 0
In some places, especially some new wells that have just been drilled,
the oil is under pressure, and it brings itself to the surface as soon as
you drill a 'pipe' for it to rise through.

In most oil wells, there's a pump bobbing up and down day and night,
pumping the oil up out of the well.

When the well is so old that even a pump isn't very effective, water is
often forced down the well under pressure, and the water forces the
oil back up through the pipe.

4. true

5. Natural selection

6. microevolution

Explanation:

Adaptive radiation is a cycle where living beings diversifying rapidly from a familial or an ancestral species into a huge number of several new types, especially when there are new environmental aspects present such as different habitats and few competitors.

Thus, it is a true statement.

Natural selection is the cycle through which a population or a species of living beings adjust and change over the period of time.  natural selection just acts upon the heritable attributes of a population by choosing for advantageous alleles or and in this manner increasing the frequency of these adaptive alleles in the population.

Thus the option Natural selection is correct.

Changes inside a genetic pool from happening to one generation to another is known as microevolution. Allele frequencies in a population may change because of, natural selection, mutation, genetic drift, and genetic flow.

Thus, the correct answer is - microevolution.
