what is mean by electromagnetic spectrum? of what type of waves does it consist?

Answers

Answer 1

Answer:

Set of electromagnetic radiation.

Explanation:

The electromagnetic spectrum is the energetic distribution of the set of electromagnetic radiation. It consists of electromagnetic waves, which are composed by an electric field and a magnetic field. Every object emits and absorbs these kinds of radiations. This spectrum encompasses from Gamma rays, which are highly energetic electromagnetic waves with high frequency and short wavelength, to Radio waves, which are low energetic electromagnetic waves with low frequency and long wavelength. The visible light, like the sunlight, is only a tiny portion of the electromagnetic spectrum, the rest of the electromagnetic waves are invisible to the human eye, like infrared light, UV light, X-rays, and microwaves, but they can be perceived and be measured with proper filters.

In a hypertonic solution, water flows through aquaporins embedded in the plasma membrane of the cell. This type of transport is best known as which if the following? A, Osmosis B. Active transport C. Facilitated diffusion D. Diffusion tS am a ati ti36of teisea

Answers

Answer:

In the given question, out of the four options

Option C. Facilitated diffusion

is correct.

Explanation:

In any hypertonic solution, flow of water is through the transporting channels known as 'aquaporins' which are embedded in the plasma membrane of the cell. Such type of transport is passive transport or passive movement of ions or molecules through a particular transmembrane protein integrated in it. This type of transport can also be referred to as passive mediated transport or commonly known as facilitated diffusion.

Final answer:

In a hypertonic solution, water moves through aquaporins in the cell membrane in a process called osmosis, a type of passive transport that plays a crucial role in regulating the internal environment of the cell.

Explanation:

In a hypertonic solution, water moves through aquaporins in the cell membrane, a process best known as osmosis. This is a type of passive transport, where water molecules diffuse across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration. Aquaporins accelerate this process by facilitating the rapid transport of water molecules, helping to maintain cellular integrity or adapt to changes in solute concentration in the extracellular environment. Osmosis plays a crucial role in the movement of water in and out of cells, highlighting the importance of cellular membranes and transport proteins in regulating the internal environment of the cell.

What is the Declination of the Celestial Equator? A) 45 degrees B) 90 degrees C)0 degrees D) Horizon

Answers

Answer:

The correct answer is option c) 0 degrees

Explanation:

In the equatorial coordinate system there are two angles which can help in locating a point on the celestial sphere. Those two angles are declination and hour angle, where declination's can be measured along the hour circle and towards the north and south of the celestial sphere. So from this information we can say that if an object is at celestial equator it would have a declination of 0 degree , with if object being at north will have +90 degree and at south it will have declination of -90 degree.

define and discuss the five dimensions of poverty as stated by the OECD DAC (POVNET)

Answers

Answer and Explanation:

The 5 dimensions of poverty stated by OECD DAC (POVNET) are as follows:

Lower income of households

It is when the income of a household of same size is comparatively smaller than the average income.

Limited and confined education

Due to lack of money as a result of lower than average income, access to proper and quality education to these poverty stricken population can not be provided adding further to their misery.

Deficit Health Insurance facilities

Another deteriorating factor as a result of poverty is lack of access to health services further restricting their growth and upliftment in the society.

Chronic poverty

Refers to the spatial concentration of poverty or geographical factors affecting poverty mostly as a result of migration of people.

High Unemployment rates

Due to lack of skills, education and accessability, rate of unemployement is high

Orographic lifting refers to
a.convection stimulated principally by local heating

b. lifting along the edges of conflicting air masses

c. forced uplift due to the presence of a physical barrier

d.none of the above

Answers

The correct answer is C. Forced uplift due to the presence of a physical barrier.

Explanation

When a current of air finds a barrier in its way, for example, a mountain, it is forced to overcome this obstacle, in this way, the air surrounds the relief that opposes and overcomes the barrier which is known in Geography as Orographic lifting.

This collision between clouds and land reliefs causes the phenomena known as windward and leeward, in which a side of the mountain works las a filter, because it takes the humidity of the clouds that clash in the mountains(windward), while the other side of the mountain or relief, receives dry air, making it a dry environment and in some cases arid (leeward). So, the correct answer is C. Forced uplift due to the presence of a physical barrier.

Why do mountains form around big bend

Answers

Answer:

The bends causes the overlaying of a crustal layer upon other layer. It results the formation of mountain on the overlying layer.

Explanation:

The big bends on the earth crust are the big faults. This fault formed due to the overlaying of a layer with other layers. The overlying crustal layer has deposits of lands on it and forms big mountains. This is a continuous and slow process. Sometimes the tectonic plate movement results in a sudden rise of some lands, and this forms new tabletop land and also dome mountains. The mountains are always formed due to the fault of the crust which are the bends on the earth.  The mountains also formed due to a volcanic eruption. Such mountains are known as volcanic or igneous mountains. This is the very reason the mountains form around big bends

Successive West African kingdoms Ghana, Mali, and Songhay a) drew upon the agricultural fertiliity of the Inland Niger River Delta b) dominated the urban centers Gao, Timbuktu, and Jenne Jeno c) controlled the trade of gold going North and salt going South d) all of the above

Answers

Answer:

The correct option is c) controlled the trade of gold going North and salt going South

Explanation:

the option a) can't be true because Niger river doesn't flow through Ghana and Songhay (but it does flow through Mali), so therefore these successive western African kingdoms can't drew upon the agricultural fertility of the inland Niger river delta.

since the option a) is not true , then we can conclude that the option d) all of the above will also not be true.

while the successive kingdoms of Mali, Ghana, Songhay do have dominance in the trade of gold and salt in the region between Sub Saharan and North Africa, so on the basis of this we can say that it is possible that these kingdoms control the trade of gold going North and salt going South.

What defines the upper and lower boundaries of subalpine ecosystems in California, and how do these vary across the state? (word limit 150)

Answers

Answer and Explanation:

the upper boundary of sub alpine ecosystem is known as tree line and lower boundary of sub alpine ecosystem is known is montane zone the tree line is the edge of habitat at which trees are capable of growing it is found at very high elevation beyond this there is no life of treesthe upper montane zone is vegetarian type generally found above the mixed coniferous forest and bellow the sub alpine forest

HOW DOES IT VARIES ACROSS THE STATE :

the marginal conditions make the sub alpine ecosystem sensitive to environment change the long lived nature of the sub alpine species make the zone a good study system

Final answer:

The upper and lower boundaries of subalpine ecosystems in California are defined by climatic conditions such as temperature and precipitation, as well as by biotic factors including the presence of specific plant species adapted to these conditions. These boundaries vary across the state due to gradients in elevation and local climate variations.

Explanation:

In California, the subalpine ecosystem is typically found at high elevations just below the alpine zone. The lower boundary is often characterized by the transition from montane forests, which include species like ponderosa pine and white fir, to subalpine forests dominated by species such as lodgepole pine, mountain hemlock, and subalpine fir. The upper boundary is marked by the point at which trees can no longer grow due to the extreme environmental conditions, transitioning into the alpine zone. Across California, these boundaries are not static and shift with changes in latitude, elevation, and aspect (the direction a slope faces), all of which affect local climate conditions, resulting in variations in the flora and fauna that can thrive in these areas.

According to the textbook, “Many experts predict that the largest increase in demand for oil in the coming years will come from increasingly industrialized economies with large populations…” (p. 140)

Can this be offset by measures taken in developed nations to address the energy–climate crisis? Why or why not? What potential strategies could be used to reduce the demand for energy in industrialized economies with large populations?

Answers

1. While there is always the possibility of being an offset, the fact point that the increasingly industrialized nations with rapidly growing large populations are constantly using more and more energy and the trend seems that it will continue. These nations have industries that grow exponentially, as well as exponentially growing populations, thus providing lot of labor force. Unlike the developed countries, these countries don't bother with investments in renewable sources of energy, but they use strictly the fossil fuels, which will just make an even bigger environmental problem in the future.

2. The best strategies that can be used by these nations to not be such big consumers of the fossils fuels is that they invest, be it on their own or with foreign aid, into the renewable resources. Most of these nations have great potential for development of such energy sources. We can take Nigeria for example, which has lot of sunny days, as well as great hydropotential, so it can focus on these two for production of energy. Pakistan is a very windy nation, and it also has lot of sunny days, and on top of it has lot of uninhabited land that can be used, so it can focus on these two for production of energy.

It is believed that this stage starts at the age of 65 years and continues till death. After we attain 65 years of age, we tend to become unproductive and we feel guilt of our past and a sense of depression feels our mind and we feel depressed and full of guilt. But if we achieve success at this age of life, it will lead to a virtue of wisdom. Thus wise people at this age has a sense of both integrity and despair.

Final answer:

Wisdom is associated with the stage of Ego Integrity vs. Despair, and the final stage of life is a time of ego integrity or despair.

Explanation:

According to Erikson, wisdom is associated with the stage of Ego Integrity versus Despair. This stage occurs in late adulthood when individuals reflect on their lives and either experience a sense of satisfaction and fulfillment (ego integrity) or feelings of regret and despair (despair).

The final stage of life is a time of ego integrity or despair. It is a time when individuals look back on their accomplishments and experiences, and assess whether they lived a meaningful life. If they feel a sense of satisfaction and acceptance, they will develop ego integrity. However, if they feel a sense of disappointment or regret, they may develop despair.
