D. Each ecosystem has a preferred disturbance frequency, Disturbances that occur at the right frequency, not too frequent or infrequent, will promote diversity at the landscape scale. Disturbances that are too frequent or to infrequent will result in biodiversity decreases.

Biodiversity refers to the variety and abundance of different species that exist within an ecosystem or region. It includes the diversity of different species, as well as the diversity within species (such as genetic diversity) and the diversity of ecosystems.

Biodiversity is important because it helps to maintain the health and functioning of ecosystems, and it is also a source of economic, cultural, and recreational value. Biodiversity can be affected by a variety of factors, including habitat loss, pollution, climate change, and the introduction of non-native species.

Disturbances are a natural part of ecosystems, but that the frequency of disturbances can affect the diversity of species in the ecosystem. It also suggests that each ecosystem has its own "preferred" disturbance frequency, and that disturbances that occur at the right frequency can promote biodiversity, while disturbances that are too frequent or too infrequent can lead to decreases in biodiversity.

Answer:

d. during the day, transpiration pulls on the water in the whole plant, causing the grapes to shrink slightly.

Explanation:

Grapes are planted in later winter or in early spring seasons and they continue their growth in the summer months. During their growth, the grapes shrink a little during the day and gain in size at night. This phenomenon is due to the grape cells are composed of a hypertonic (concentrated) sugar solution that during the day lost water by osmosis, thereby shrinking the cytoplasm.

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.

Therefore, these pores present in the thin hyphal cells of the fungus allows chemical movements in the cells.

Answer:

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.

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.

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.

Answer:

Hematological parameters in adolescent as inhomogeneous population are not quantified sufficiently, especially hematological indices. RBC variables, regardless of the age, differ very much between male and female examinees, in favor of the male examinees. Hematological indices were insignificantly higher in males. Regarding the age of examinees, RBC variables showed significant inter-groups differences only within male adolescents. While with girls, ages span 8 to 18 yr, we did not find significant differences for most of the hematological variables.
