Explanation:
Green house effect occurs when the wavelenght of the infrared radiation in the incident solar radiation, looses some of its energy on reflection from the earth surface, making it longer and unable to pass through the greenhouse gases that act like a blanket around the earth.
The reflected radiation has a longer wavelenght because it looses energy to the earth as heat; leaving it with a new wavelenght too long to go through the greenhouse gases.
The jar envoirment does not provide the earth-like material that can absorbs some of the energy of the incident radiation so it goes out with relatively the same energy. Also, the refractive index of the green house gases and the glass used in the lab might not be the same so modeling it with a glass might not produce the same effect.
Finally, the light source used might not contain enough infrared energy as an incident solar radiation.
I think the last one but don’t quote me on that

Answer:
Brain drain is the emigration of individual who are highly proficient or qualified in their field of study .
Explanation:
Brain drain is the emigration of individual who are highly proficient or qualified in their field of study . The departure of these group of professional may be due to better living condition or higher salary.
In other words brain drain is when a country losses it talented or highly skilled or educated workers to other countries through migration. Brain drain is considered a big problem to the society because competent hands migrates to another country causing more economic hardship to the country they left. The emigrants contribute to the expertise of another country. This kind of movement occurs from a developing countries to a developed country.
The impacts of Brain drain on developing countries are numerous but it is more on the negative side.
The phenomenon has caused a harmful effect on developing countries mostly in Africa. As this talented individuals move to a developed countries they become richer and the developing countries becomes poorer. The resulting impact in developing countries are lack of innovation and industrial growth, economic instability which leads to unemployment , Political instability and loss of the country's investment in education , loss of tax revenue and shortage of skilled workers.
The positive impact is that the workers from developing countries tend to improve in skills . Another benefits is remittance; this skilled workers from developing countries might send money home and this might stimulate the economy.
