Answer:
The correct answer would be option D, Because of the nature of digital signals are immune to noise and imperfections.
Explanation:
Analog signals are the signals which changes over time. Analog signals consists of continuous waves, where as a digital signal is a discrete wave which transfers data in the form of 0 and 1, which is called the binary form.
Analog signals are subjected to deterioration while transmitting data from one point to another, whereas digital signals are immune to noise and imperfections. Digital signals have noise immunity and less susceptibility to interference caused by noise during the transmission of data.
In the years from 1900 to the present, life expectancy in the United States has drastically increased.
The tremendous increase in life expectancy during the last century may be the greatest human achievement.
In the 110 years between 1900 and 2010, the United States' life expectancy at birth increased from 47.3 to 78.7 years (Centers for Disease Control and Prevention/National Center for Health Statistics [CDC/NCHS], 2012, 2013). Declines in infectious diseases and fatalities disproportionately among the young caused this longer lifespan. After infectious diseases accounted for the majority of deaths, the leading causes of mortality were cancer and cardiovascular diseases. In the second half of the 20th century, these then became the focus of science and medicine.

Answer:
According to Annalisa Rossi Del Corso research on Intergenerational relationships (1990), <em>the flow of support between parents and children is reverting with aging of both groups</em>.
Explanation:
Meaning that when children are young, parents provide more support to them. Meanwhile, when parents become older children start to provide support to their parents, and support coming from parents is decreasing. As a result of this process, parents turn from givers to receivers.
In the beginning of Intergenerational relationships, parents are 100% givers and children are 100% receivers. When children grow up, the <u>ratio between support received and support given changes</u>. For example, at the age of 25 child receives 60% of support from parents and provides 40% of support back.
