D phytoplankton i believe
Answer:
I have identified <em>Escherichia coli </em>and<em> Bacillus sp.</em>
Explanation:
I obtained my sample from soil, in a park near my house. The common bacteria on soil are gram positive and gram negative.
I found rods, and some are gram positive and long. They others are gram negative and very small and short.
The color of the gram positive is a dark blue, almost purple, and they are big and abundant, they are almost in lines, so I think they are a species of <em>Bacillus.</em>
The gram negative bacteria are extremely small and they look hot pink. They are very probably enterobacteria, and the most common enterobacteria is <em>Escherichia coli</em>. They do not have a particular order of arrangement.
<span>James Ussher was a creative scholar, a church leader
and became famous for his genuine letters of the church. He is the Archbishop
of all Ireland and majorly impacted Reformation theology. He is best
known for his chronology research that concluded Adam was created in 4004
B.C. In reality, Ussher was a first-class scholar very involved in
scholarly research. He regularly interacted with “the most learned men of the
day” to intellectually savor their ideas. He was also “a real connoisseur of
books,” and there was scarcely a book in any British library that he was
unfamiliar with. While James Hutton is known as the Father of Modern Geology,
Hutton is a Scottish Geologist and a naturalist who originated the concept of
earth’s crust during geological history, which explains the features of the
Earth's crust by means of natural processes over geologic time. Hutton
had formulated controversial theories of the origin of the earth and of
atmospheric changes known as 'uniformitarian’s'. This paved the way for modern
geological science.</span>
Answer:
The earth is a vast, complex system powered by two sources of energy: an internal source (the decay of radioactive elements in the geosphere, which generates geothermal heat) and an external source (the solar radiation received from the Sun); the vast majority of the energy in the earth system comes from the Sun.
Everything in Earth's system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called "spheres." Specifically, they are the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air).
