In chemistry and physics, the atomic theory explains how our understanding of the atom has changed over time. Atoms were once thought to be the smallest pieces of matter. However, it is now known that atoms are made up of protons, neutrons, and electrons. These subatomic particles are made up of quarks. The first idea of the atom came from the Greek philosopher Democritus. A lot of the ideas in the modern theory came from John Dalton, a British chemist and physicist.

The theory applies to solids, liquids and gases, but it does not apply in quite the same way to plasmas or neutron stars.

s344n2d4d5 [400]

Answer:

There is a higher concentration of people who live in the northern hemisphere than the southern hemisphere.

Explanation:

A is not correct because the equatorial region is not densely populated, but it is actually sparsely populated.

B is not correct because the southern hemisphere doesn't have a higher concetration of people than the northern hemisphere.

C is not correct because if that was the case the population density would have been the highest either on the Equator or the poles, and that is not the case at all.

D is not correct because the population density is related to the concept of agricultural production.

E is correct because the northern hemisphere has a higher concentration of population than the southern hemisphere, and this is largely due to the fact that there is much more land on the northern hemisphere, thus a much larger area where there are suitable conditions for living.

What is your reflection on the lifeboat ethics by hardin (a half page answer)?
Ray Of Light [21]

Answer:

Explanation:

A lifeboat is a boat, specially made to move from land to sea to help people who are in difficulty. Garrett James Hardin, an American environmentalist uses this description of lifeboat to warn of the dangers of human overpopulation which does not only affect the populated nations but everyone. The rich people (mostly the Americans) are the ones in the lifeboats, and the poor ones are in the waters swimming and trying to board any of the lifeboats. The nations who are like lifeboats have a specific-carrying capacity (or limited amount) that should not be exceeded.  

If there are fifty people in the lifeboats with ten free spaces that could be given to hundred poor people waiting to be saved, further explanations were offered by Hardin on what to be done. Allowing everyone in, which would mean hundred and fifty people are in the boat at the same time could make it sink. The ten spaces could be offered on who arrives first or the best ten from the hundred poor people could be allowed to come on board. There are some people, among the lucky fifty rich people who would feel guilty according to Hardin, that the remaining ninety could die and so they are willing to give-up their spaces for the less fortunate ones. The best solution would be for no one to be allowed into the boat, preserving the lucky fifty from sinking with the boat as stated by Hardin.  

Nations are not actually lifeboats and the human race have grown beyond being measured to have a limited number of persons it can contain as stated by Hardin. The possible maximum number of persons a particular area can contain should never be important to mankind where there is a terrible event affecting human beings. Also the lucky fifty in the lifeboats may think they are safe, but they could be affected by a huge wave in the sea that would make the entire lifeboat nations to drown.
