Answer:
Use 400 x in order to study the structure clearly.
Explanation:
Cell structures could be clearly identified when magnify the microscope about 400 x by using a compound microscope. Due to high magnification power of compound microscope, the individual is able to see different structures that are present in cells. while by using lower magnification, the individual is unable to see different structures clearly. So use high magnification in order to study the cell.

Prokaryotes are structurally simple organisms that have existed for over two billion years.
Which of the following are prokaryotes?
Choose 1 answer:
(Choice A)
A
Animals
(Choice B)
B
Bacteria
(Choice C)
C
Plants
(Choice D)
D
Fungi
Answer:
choice B
Explanation:
Bacteria are super small single-celled organisms that thrive in many environments.
Bacteria are single celled organism which are described as the prokaryotes. So, the correct option is B.
What are Prokaryotes?A prokaryote is defined as a single-celled organism that lacks a nucleus and other membrane-bound organelles. Prokaryotes were classified within the kingdom Prokaryota.
Prokaryotic cells are described as single-celled microorganisms that are the earliest known on Earth which include bacteria and archaea. Photosynthetic prokaryotes include cyanobacteria that photosynthesize that have a single cell membrane and, therefore, all reactions occur within the cytoplasm.
Bacteria are examples of the prokaryotic cell type, some example is E. coli.
Thus, Bacteria are single celled organism which are described as the prokaryotes. So, the correct option is B.

Identify the living and non-living parts of the nitrogen cycle.
The nitrogen cycle is a cyclical process in which nitrogen moves through both living and non-living things, including the atmosphere, soil, water, plants, animals, and bacteria.
What is nitrogen cycle?The Nitrogen Cycle is a biogeochemical process in which nitrogen is converted into various forms before passing from the atmosphere to the soil to the organism and back into the atmosphere.
Nitrogen fixation, nitrification, denitrification, decay, and putrefaction are some of the processes involved.
Nitrogen fixation, nitrification, and denitrification are the three major steps in the nitrogen cycle.
It is a biosphere cycle that includes the atmosphere, hydrosphere, and lithosphere. Nitrogen can be found in a variety of reservoirs.
The nitrogen cycle is a cyclical methodology in which nitrogen moves through both living and nonliving systems such as the atmosphere, soil, water, plants, animals, as well as bacteria.
Thus, these are some living and non-living parts of nitrogen cycle.

what makes jupiter similar to the sun
Answer:
Their composition is similar.
Explanation:
They are mostly made of hydrogen and helium.
The structure of jupiter and sun mostly made up of hydrogen and helium.
What are the characteristics of hydrogen and helium?Hydrogen and helium are the lightest elements in the periodic table. They exist as gases at room temperature and are the two most common elements in the universe, with hydrogen making up about 75% of all matter.
It will form a mixture of two of the lightest gases known. Though Hydrogen atoms (H) turn into hydrogen molecules (H2) to form a very reactive, flammable, and explosive hydrogen gas, Helium (He) atoms form an inert gas.
The key difference between hydrogen and helium is that hydrogen is a diatomic gas, while helium is a monatomic gas. Helium has a fully filled s orbital (1s2), but in hydrogen, there is only one electron, so it is unstable.

What was the most common form of sea life found in Oklahoma? dolomite trilobite bryozoans apatosaurus
Answer:
The correct answer is: trilobite.
Explanation:
Trilobites were the most common form of early sea life found in Oklahoma. Trilobites were arthropods that are now extinct. This marine species is thought to have lived during the early Cambrian period and they existed for almost 300 million years, before disappearing at the end of the Permian in the Permian-Triassic extinction event.
Dolomite is a sedimentary carbonate rock that is rich in calcium.
Bryozoans are a species of seaweed-like aquatic invertebrate animals that have lived since the early Ordovician period.
The Apatosaurus was a herbivore dinosaur that lived in North America during the Jurassic period. They had very long necks and were related to the Brontosaurus.
