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.

The prosperity of the 1920s led to new patterns of consumption, or purchasing consumer goods like radios, cars, vacuums, beauty products or clothing. The expansion of credit in the 1920s allowed for the sale of more consumer goods and put automobiles within reach of average Americans.
You can use this as reasoning for it being a positive.
Answer:
In the deep ocean layers where the sunlight does not reach, these organisms that are chemoautotrophic use sulfides from the hydrothermal vents to perform chemosynthesis instead of photosynthesis.
Explanation:
Chemoautotrophic organisms are the ones that are adapted to the absence of sunlight. Such organisms identify electron donors in their vicinity and derive energy from the oxidation reactions that these electron donors (mostly, inorganic compounds) undergo.
The major reason for the development of such a trait in these organisms is the depth that they live at. On deep-sea floors, there is an abundance of sulfides. Thus, the organisms living on there make use of the sulfides to fix carbon and obtain energy the required energy to sustain.
The process of chemosynthesis occurring on deep-sea floors due to the presence of carbon, sulfides, and oxygen culminates in the production of organic materials as an end result which the organisms feed on and sustain even when there is no sunlight available. These organisms majorly belong to the bacteria species called Archaea and Extremophiles.

Weather is the variable condition of atmosphere as it changing over time. Weather is the condition of the variables of the atmosphere at any specific location for a small period of time an example is Weather processes such as wind, clouds, and precipitation are all the result of the atmosphere responding to uneven heating of the Earth by the Sun. .vertical heat transport: Solar heating of the Earth's surface makes the atmosphere convectively unstable, causing vertical air currents to develop.
Answer: Option B - False
