Hey there! 

Airplanes must be pressurized when flying at high altitudes so that the oxygen levels stay normal for us to breathe. The higher you go up, the thinner the air gets, which causes breathing problems for us humans. 

Thank you!

Como a analise do perfil de uma populaçao pode contribuir para o planejamento governamental
malfutka [58]

Answer:

The planning of governments when it comes to running their countries is always based on demographics, and this is because the characteristics of the population are crucial for the planning and which direction it will go.

Explanation:

Every government makes plans about running the country based on the demographic characteristics of its population. The reason for this is that the characteristics of the population are crucial for developing and focusing on certain sectors or avoiding others. Each country in the world has its own unique population with unique characteristics and this brings in a lot of different policies by the different governments.

If a population is highly educated, the government can focus its planning on the territary and quaternary economic sectors, as it will primarily have a labor force that would be most efficient in these sectors. If a population is very young, uneducated, and with a low level of skills, the chances are that the government will focus the country toward agriculture and extraction of natural resources, thus the primary sector. If a population is old and it is projected to get older then the government would most probably adopt a policy to invite people from other countries to move in that will contribute to its socio-economic development.

Using complete sentences, explain the influence, power, and limits of the United Nations Declaration of Human Rights.
sergij07 [2.7K]

Answer:

The essential value of the Universal Declaration of Human Rights, lays in the establishment and protection of individual's fundamental freedoms and rights. Although this document does not have the power to impose any obligations on a domestic level, it has served to bind international law's customs and propel the development of countless treaties, national constitutions, etc. Not losing sight of its limitations we can still see the massive influence it's had, in particular when it came to defining the meaning of these "fundamental freedoms" and "human rights". All members of the United Nations have adopted these igniting principles and commited to further developing the tools to secure and protect them for their citizens.

(Hope this helped you have a blessed day!!)
