If the population of Shanghai increases to 30 billion people, how much land would its people need if the population density is 3
nadezda [96]

784109 People per sq. mi land would its people need if the population density is 3,826 people/km2.

<h3>What is population density?</h3>

The density of individuals within a species in a given geographic location is referred to as population density. Data on population density can be used to calculate demographics and examine interactions with ecosystems, human health, and infrastructure.

The population density equation below can be used to calculate the population density of a piece of land:

        Population Density = Population/ Area

The residential density is important in determining the people's thinking and culture. Engineers find it vital to forecast population growth in order to develop infrastructure that can support a large population. It is practically impossible to develop a perfect 3D model of any structure that allows the largest number of people to live without this understanding.

• why is gc typically limited to molecules that weigh less than 400 amu?
Anna35 [415]

Gas chromatography (GC) is a method of separating mixed compounds. The separation will depend on each compound's retention time. Compounds with higher molecular weights will elute out slower than those with lower molecular weight. This is due to their difference in boiling points. The larger the structure, the higher the boiling point.

Nadusha1986 [10]
The answer is <span>Topoisomerase.

Topoisomerase is an enzyme responsible for twisting of DNA helix. After DNA strand is untwisted by helicase enzyme, DNA must be twisted again so the normal function of DNA can be sustained. If left untwisted, the replication fork will continue to grow, the normal function of DNA will stop.</span>
