Answer:

D: All of the above

These are all sources for sediments

The correct option is D. all of the above are a source of sediments.

What are sediments?

According to geologists, sediment is any solid Earth surface material that can be transferred and dumped in a new location, whether it be on land or in water.

Because sediment particles are easily picked up by water, wind, and ice and transported to new locations, erosion is a significant driver of sediment mobility.

Pebbles and gravel are deposited further downstream, notably in lowland deltas where river mouths open up to the ocean, as water runs over land and through the creek and river basins.

Therefore, The correct option is D. all of the above are a source of sediments.

Answers

Answer:

D . The atomic number and atomic mass decrease from left to right across a period;

energy levels increase from top to bottom down a group.

Explanation:

On the periodic table, elements are arranged based on the periodic law. This law states that "the properties of elements are a periodic function of their atomic number".

The atomic number is the number of protons in an atom.

Atomic mass is the number of protons and neutrons in an atom

The energy level is the number of shells in an atom

As we move from left to right on the periodic table, both atomic mass and atomic number increases. Also, down a group, the energy level increases as the number period increases. From left to right, the energy level stays the same.

ANSWER ASAP PLEASE Explain the meaning of the term "soil taxonomy," using taxonomic examples to illustrate application of the field.

Answers

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.

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.

HELP ASAP PLEASE!!!

Answers

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.
