Certain bacteria change nitrogen gas into a usable form in a process called nitrogen fixation.
What is nitrogen fixation?Nitrogen fixation process is important for the growth of plants, as nitrogen is an essential component of many plant nutrients. Nitrogen fixation is primarily carried out by bacteria in the genus Rhizobia, which form symbiotic relationships with certain plants, such as legumes. The bacteria live in nodules on the roots of these plants and convert atmospheric nitrogen into a form that can be used by the plant.
This process is also important for the overall health of the soil, as it helps to increase the availability of nitrogen for other organisms in the ecosystem.

What are chemical reactions?Chemical reactions are defined as reactions which occur when a substance combines with another substance to form a new substance.Alternatively, when a substance breaks down or decomposes to give new substances it is also considered to be a chemical reaction.
There are several characteristics of chemical reactions like change in color, change in state , change in odor and change in composition . During chemical reaction there is also formation of precipitate an insoluble mass of substance or even evolution of gases.
There are three types of chemical reactions:
1) inorganic reactions
2)organic reactions
3) biochemical reactions
During chemical reactions atoms are rearranged and changes are accompanied by an energy change as new substances are formed.

ANSWER ASAP PLEASE Explain the meaning of the term "soil taxonomy," using taxonomic examples to illustrate application of the field.
Answer:
Soil in this text is a natural body comprised of solids
(minerals and organic matter), liquid, and gases that occurs
on the land surface, occupies space, and is characterized by
one or both of the following: horizons, or layers, that are
distinguishable from the initial material as a result of additions,
losses, transfers, and transformations of energy and matter or
the ability to support rooted plants in a natural environment
(Soil Survey Staff, 1999). This definition is expanded from the
previous version of Soil Taxonomy (Soil Survey Staff, 1975) to
include soils in areas of Antarctica where pedogenesis occurs
but where the climate is too harsh to support the higher plant
forms.
The upper limit of soil is the boundary between soil and
either air, shallow water, live plants, or plant materials that
have not begun to decompose. Areas are not considered to have
soil if the surface is permanently covered by water too deep
(typically more than about 2.5 m) for the growth of rooted
plants. The horizontal boundaries of soil are areas where the soil
grades to deep water, barren areas, rock, or ice. In some places
the separation between soil and non soil is so gradual that clear
distinctions cannot be made.
The lower boundary that separates soil from the non soil
underneath is most difficult to define. Soil consists of the
horizons near the earth’s surface that, in contrast to the
underlying parent material, have been altered by the interactions
of climate, relief, and living organisms over time. Commonly,
soil grades at its lower boundary to hard rock or to earthy
materials virtually devoid of animals, roots, or other marks
of biological activity. The lowest depth of biological activity,
however, is difficult to discern and is often gradual. For
the practicality of soil survey, the lower boundary of soil is
arbitrarily set at 200 cm. In soils where either biological activity
or current pedogenic processes extend to depths greater than
200 cm, the lower limit of the soil for classification purposes
is still 200 cm. In some instances the more weakly cemented
bedrocks (paralithic materials, defined later) and uncemented
bedrocks (some densic materials, defined later) have been
described below the lower boundary of soil and used to
differentiate soil series (series control section, defined in chapter
17). This is permissible even though the paralithic materials
below a paralithic contact are not considered soil in the true
sense. In areas where soil has thin, pedagogically cemented
horizons that are impermeable to roots, the soil extends as
deep as the deepest cemented horizon, but not below 200 cm.
For certain management goals, layers deeper than the lower
boundary of the soil that is classified (200 cm) must also be
described if they affect the content and movement of water and
air or other interpretative concerns.
In the humid tropics, earthy materials may extend to a depth
of many meters with no obvious changes below the upper 1 or
2 m, except for an occasional stone line. In many wet soils,
gleyed soil material may begin a few centimeters below the
surface and, in some areas, continue down for several meters
apparently unchanged with increasing depth. The latter
condition can arise through the gradual filling of a wet basin
in which the A horizon is gradually added to the surface and
becomes gleyed beneath. Finally, the A horizon rests on a thick
mass of gleyed material that may be relatively uniform. In both
of these situations, there is no alternative but to set the lower
limit of soil at the arbitrary limit of 200 cm.
Soil, as defined in this text, does not need to have discernible
genetic horizons, although the presence or absence of genetic
horizons and their nature are of extreme importance in soil
classification. Plants can be grown under glass in pots filled
with earthy materials, such as peat or sand, or even in water.
Under proper conditions all these media are productive for
plants, but they are non soil here in the sense that they cannot
be classified in the same system that is used for the soils of a
survey area, county, or even nation. Plants even grow on trees
or in cracks of exposed bedrock (i.e., rock outcrop), but trees
and rock outcrop are regarded as non soil.
Soil has many temporal properties that fluctuate hourly,
daily, and seasonally. It may be alternately cold, warm, dry,
or moist. Biological activity is slowed or stopped if the soil
becomes too cold or too dry. The soil receives additions of
fresh, undecomposed organic matter when leaves fall or grasses
die. Soil is not static. The pH, soluble salts, amount of organic
matter and carbon-nitrogen ratio, numbers of microorganisms,
soil fauna, temperature, and moisture status all change with
the seasons as well as with more extended periods of time.
Soil must be viewed from both the short-term and long-term
perspective.

7. Suggest an experiment that could be used to determine the function of the proteins in the
plasma membrane.
HELP ASAP PLEASE!!!
plasma membrane proteins carry out functions as diverse as ferrying nutrients across the plasma membrane, receiving chemical signals from outside the cell, translating chemical signals into intracellular action
The protein plays an important role in the plasma membrane, such as acting as a receptor, a channel, a carrier, etc. The experiment that explains the plasma membrane is called FRAP, or fluorescence recovery after photobleaching.
What is the role of proteins in the plasma membrane?The plasma membrane has both lipids and proteins in it; the lipids and proteins are arranged in such a way that they maintain the equilibrium of the cell. The proteins are present inside the cell and on the surfaces of the cell as receptors, channels, etc. Inside the cell, enzymes and other proteins, such as the cytoskeleton, are present, while the cell surface has receptors that bind with the ligand, such as hormones or neurotransmitters, etc.
The proteins are generally present in their secondary form in the cell membrane as receptors, and there is technology that can detect their functions and mobility. One experiment is fluorescence recovery after photobleaching (FRAP), in which a specific area of the cell membrane is bleached and then the movement is seen with the help of fluorescence.
Hence, the correct answer is that, with the help of FRAP, the movement and function is seen in the cell membrane.

what propels the movement of chemicals like carbohydrate through the thin hyphal cells of the fungus
Answer:
There are no options to this question, however, it will be answered based on general understanding of fungal hyphae.
The pores/holes in the septa of the hyphae
Explanation:
Fungi are a group of living organisms that are different from plant and animals. They are made up of a thread-like filamentous structure called HYPHA that develops into a mass of vegetative structure called MYCELIUM. The hyphae of most fungi is septated i.e. divided by a septum, which is a partition that divides the hyphae in fungi.
In the septum of fungi cells are tiny pores that propels the movement of chemicals like carbohydrate through the thin hyphal cells i.e. molecules pass through these pores located in the septum from one hypha to another within the cell of a fungus.
Carbohydrates are molecules made up of carbon, hydrogen and oxygen. They are required for cellular metabolism and functions. The vegetative mode of growth is performed by the hyphal cells in the fungi.
The openings or the septa in hyphal cells force the carbohydrates into the cells.
Fungi or fungus is a group of organisms that varies from animals and plants.The filamentous thread-like formation called hypha is the structural unit of fungi organisation.The hyphal cells are divided by septum that divides the fungi cells.In the septum present on the hyphal cells, many numerous pores present drives the flow of the chemical or the nutrient like carbohydrates.Therefore, these pores present in the thin hyphal cells of the fungus allows chemical movements in the cells.
