Answer:
4) abstract; concrete
Explanation:
Alene is able to easily understant abstract concepts and ideas, which is why she comments the reasoning about the conclusion of the apple A being bigger than apple C. Aline shows an abstract thought, while Janis shows a concrete thought as evidenced in her only being able to "get it" after Alene explained again, using the physical apples. She needed to see a physical object in order to understand the idea.
Answer:
Deforestation, and especially the destruction of rainforests, is a hugely significant contributor to climate change. Scientists estimate that forest loss and other changes to the use of land account for around 23% of current man-made CO2 emissions – which equates to 17% of the 100-year warming impact of all current greenhouse-gas emissions.
As children are taught at school, trees and other plants absorb CO2 from the air as they grow. Using energy from the sun, they turn the carbon captured from the CO2 molecules into building blocks for their trunks, branches and foliage. This is all part of the carbon cycle.
A mature forest doesn't necessarily absorb much more CO2 that it releases, however, because when each tree dies and either rots down or is burned, much of its stored carbon is released once again. In other words, in the context of climate change, the most important thing about mature forests is not that they reduce the amount of CO2 in the air but that they are huge reservoirs of stored carbon. If such a forest is burned or cleared then much of that carbon is released back into the atmosphere, adding to atmospheric CO2 levels.
Of course, the same process also works in reverse. If trees are planted where previously there weren't any, they will on soak up CO2 as they grow, reducing the amount of greenhouse gas in the atmosphere. It is thought that trees, plants and other land-based "carbon sinks" currently soak up more than a quarter of all the CO2 that humans add to the air each year – though that figure could change as the planet warms.
Unsurprisingly, the relationship between trees and local and global temperature is more complicated than the simple question of the greenhouse gases they absorb and emit. Forests have a major impact on local weather systems and can also affect the amount of sunlight absorbed by the planet: a new area of trees in a snowy region may create more warming than cooling overall by darkening the land surface and reducing the amount of sunlight reflected back to space.
Explanation:
Christmas is a value to family because it is a time of giving, loving, and appreciating what you have.
Answer:
Considered dead
Explanation:
Brain death is very difficult to assess and describe because family members and non-neurologist can understand the situation. Now there are coming some guidelines that help a physician can understand brain death with the time in adults or children.
This principle has been challenged in court. Usually, people get confused with coma and brain death. In a coma, the person becomes in a vegetative stage. A person is in deep sleep and may survive.
The person who is in a vegetative state has a function in the lower state. Coma will not progress the brain death. The patient who gets a brain death has not any symptoms as we can see in a coma.
Answer:
Life for people in Europe during the Middle Ages was highly stratified because of the feudal system. There was very little social mobility and it is called The Dark Ages because culturally and intellectually there were fewer contributions than had been made by ancient Greece and Rome.
Explanation:
The Middle Ages is a term that describes the period from the fall of the Western Roman Empire in the year 476 until about 1450. This period of time is also called The Dark Ages, because some perceive Europe as having been plunged into darkness when the Roman Empire fell. The Middle Ages supposedly lacked scientific and cultural advancement, especially when compared to the accomplishments of ancient Greece and Rome. The feudal system made it difficult for there to be social mobility and this added to a sense of bleakness about this time for the common person. However, in the High Middle Ages after the year 1000 there was a surge in population in Europe, suggesting that there was more prosperity and better health and an improved supply of food. The Black Death that swept through Europe from 1346-53 impacted this growth and views of medieval city life.
