It can cause earthquakes, tsunamis, hurricanes, and other natural disasters depending on where you live.

In short, opportunity cost is the way we define value. It is central to our economic understanding, and is the idea that any given product or service can only be calculated to be worth everything else it's resources could have been used for.

For example, let's say that you are in a store have $10. $10 is a resource you could use to either buy a sandwich and a soda for now, or to buy a frozen pizza for dinner later. For the sake of the example, you want both and afterwards will not afford the one you do not buy. Let us say that you buy a soda and sandwich. That then comes at the opportunity cost of not getting the frozen pizza for dinner.

Opportunity cost is trade-offs.

Total opportunity cost would therefore be a sum of various different trade-offs, calculated into a total sum of resources.

Social "science" is generally taken to include anthropology, economics, history, political "science," psychology and sociology.

A person need to study work ethics so that they can work in the business community well and succeed. If a person does not have some form of work ethic, they will not be able to keep a job.

Think of something unique something that no one would think of like for example how does the holocaust still affect people in Europe today..... :)

Banking finance is a part of economics which is backbone of any countries economic growth, monetary stability and helps countries to become underdeveloped to developed and powerful too.

Both. It is correct to consider age as a continuous variable, but we collect data on people's ages as if they were discrete variables. Age is generally given in years, at least in humans. When we round off our numbers, we make age a discrete variable. We say a person turns 21 as if one day he's 20 years old and the next day he's 21 years old. This is the way we treat age as a discrete variable. If we considered age as a continuous variable, we would say he is 20.99 years old a day before his birthday and exactly 21 years old only on his birthday, on the exact time of his birth. After that he is 21.001 years old.

Four days of the week are named after Viking gods.

earthquakes tend to happer near the boundaries of the plates, places like Japan and some parts of Califfornia are on fault lines or close to plates, which move, when that happens- you get bearthquakes- although I'm not entirely sure.

Many strong earthquakes occur among destructive plate margins, this is because great stresses build up in the subduction zone as one plate is forced down below the other, this energy builds up to great force and is then released in an earthquake.

An experimental investigation is carried out so that people can better understand why the causes of an event occur. Teachers often use this technique to encourage children to be active learners.

There are over 60 million Hispanics in the United States. There are about 24 million blacks. The Hispanics will continue to grow as most are Catholics and do not believe in family planning or birth control. The Hispanics are by far the largest minority in this country. There is another 12 million undocumented Hispanics. In 20 years, there will be over 75 million Hispanics and it will be wise to learn Spanish.

§As any ten year old can tell us, the Earth rotates around the sun once every year. At the same time, the planet tilts on its axis, and this has an even more dramatic effect on the weather. The popular belief that winter is caused as the Earth moves away from the Sun during the widest part of its orbit, and thus causes winter, is not true. In actual fact, winter occurs when the sun is at it's closest point.

§The planet tilts 23°27' (23 degrees 27 minutes) and this causes different parts of the Earth's surface to be closer to the sun at various parts of its orbit. It is this variation that brings about the seasons. In winter, the northern hemisphere is tilted away from the sun and thus experiences colder temperatures. Since the southern hemisphere will be tilted toward the sun at this point, it's seasons are always the opposite of ours.

During the winter, the light rays coming in from the sun hit the Earth surface at a lower angle. Less energy is transferred to the surface as a result of the glancing nature of these rays. Basically, the same amount of light energy is spread out over a larger area. This effect is compounded by the larger distance this light must travel through the atmosphere, allowing it to absorb more of this already limited he

The historical foundation of the role of a nursing as a teacher or educator can be identified in the mid 1880's. Nurses at that time played a big role in the education of children.

What is classical condition what is instrumental learning or cooperation condition, learning observtional learning

I can attmpt to answer as follows: Any human behavior is a learned responde, we learn on the behavior which are observed, there are some behavior which ar covert and others are overcovers(seen and cannot being seen) some behavior you learn them volunterinly e.g a child when he is at 1.3 yrs you learn your mother/father behavior there some behaviour we learn through observation eg watching a TV we learn a certain behavior by watching a TV.

Saying that oxygenated anddeoxygenated blood never mix is a bit misleading. First lets start with the bodies pump, the heart. The heart is divided into four parts, the Left having two parts (L atria and L ventricle) and the Right having two parts (R atria and R ventricle). The Left side of the heart receives oxygenated blood from the lungs first in the L atrium and then into the L ventricle. The L ventricle pumps the blood to the rest of your body through arteries. It is at the level of the capillaries, tiny blood vessels, that oxygenated blood donates it's oxygen to tissue, and hence becomes de-oxygenated. This again is a little misleading because it is not devoid of oxygen, it just has much less oxygen than before the donation. After the donation of oxygen at the capillary the blood is now on the venous side and returns the de-oxygenated blood to the heart. This oxygen poor blood arrives on the R side of the heart in the R atrium and then the R ventricle where it is pumped to the lungs to become oxygenated and then returned to the L atrium and the cycle continues. There are however, disorders of the heart, (ie PDA), that allow de-oxygenated and oxygenated blood to mix in the heart. This leads to poorly oxygenated blood being delivered to tissues.

There are so many reasons why scientists monitor volcanoes. The main objective it to fully understand how they happen and also observe patterns that would aid in predicting volcanoes before they can happen.

Meaning depends on context and audience. For instance, you could make the observation that President Obama is black but this would be a pointless observation since most people already know it. In fact the observation is so obvious the president used it as a joke on a late night TV channel.

So for an observation to be meaningful it needs to be pertinent, relevant, timely, precise and accurate.


If we are trying to launch a vehicle into space and you note that the acceleration constant for the earth's gravity had changed by 1percent. This would be startling, timely, and maybe even alarming. If it turned out that the measurement was not repeatable the observation would be not be meaningful. It would probably just be annoying.

For the most part in science, the most meaningful observations are repeatable.
