Answer:In the upper thermosphere, atomic oxygen (O), atomic nitrogen (N), and helium (He) are the main components of air. ... Earth's ionosphere, composed of several regions of such ionized particles in the atmosphere, overlaps with and shares the same space with the electrically neutral thermosphere. I hope that helps if not let me know and ill try my best to explain it better:)
Answer:
Since it is likely that the weeds in the lake act as a food source for organisms within that ecosystem, killing all the weeds would harm the population that feeds off them, and in turn the populations that feed off of them.
Darwin’s
research showed that finches beaks are different to fit their food source. It
also started the theories of evolution and natural selection. The
Grant’s research on the Galapagos Islands showed that evolution exists and can
happen over a course of two years. They proved Darwin’s theories are true. Since
all the plants and animals are native to the islands, they had to adapt to the
new food source and climate. Beaks, size, etc. are all changes made to these
organisms to be able to live on the islands.
The Galapagos Islands are located in Ecuador and
sit on the Pacific Ocean. <span>The Galapagos Islands were formed from 3 million
to 5 million years ago. Volcanic eruptions typically shield volcanoes formed
the islands. They are located over a “particularly hot mantel” that causes
volcanic activity. The outcome of many eruptions were islands because the left
overs were pushed to the surface. The Galapagos islands are pretty big reaching
an area of 3,093 miles. The temperatures range from 69 to 84 degrees creating a
typically warm climate. </span>
Darwin studied medicine at age 16, but became
fascinated specimens around the globe. He developed theories of natural
selection and evolution. While he was on the Galapagos islands, he studied
thirteen different species of finches.
He observed finches and different beak
structures. He observed their ability to consume foods such as nuts, bugs, and
fruit. He concluded all were related to their beaks. For example, long, slender
beaks are good to reach in the flowers of a cactus.
<span>Charles concluded that the finches beaks are
examples of adaptive radiation. To fit in the island, they had to adapt to the
conditions. This lead to Charles’ theory of natural selection. </span>
Charles came to the conclusion of evolution and
natural selection. Natural selection is the process where organisms adapt to their environment to survive and
produce more offspring. Evolution is where different kinds of living organisms
are thought to have developed. These theories have changed science forever and
leave today’s scientists marveling of his theories.

A=
In the nature there are four fundamental forces, namely nuclear force, electromagnetic force, weak force, and gravitational force. These forces are arranged with respect to their strengths in descending order.
The nuclear forces are of greater strengths.
These bind up the protons and the neutrons in an atom together. The nuclear forces are strong enough to combine the quarks that form the nucleons.
B= The weak forces of the interaction are the forces that are short ranged and cause the instability of the nucleus. These are 1/10^5 times of the nuclear forces.
C= The electromagnetic forces are the forces that which combine the atoms and the molecules that intend form the ordinary matter. The electromagnetic forces are 1/10^5times of the nuclear forces.
D= The gravitational forces are 1/10^5 times of the nuclear force.
