If the population of Shanghai increases to 30 billion people, how much land would its people need if the population density is 3,826 people/km2 ?

Answers

Answer 1

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

What is population density?

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.

Explanation:

Blood sugar is too high. Pancreas releases insulin to stimulate the liver and store glucose to break down sugar from the blood and store it as glycogen or glucose. Blood sugar levels decreases.

Blood sugar level is too low. Pancreas releases glucagon to stimulate the glucose production in the liver and maintain adequate plasma glucose concentrations to convert stored glucagon and fat back into glucose to be released in the blood. Blood sugar levels increases.

An earthworm's body plan consists of all, EXCEPT  pores in the skin for food to move in and a stomach in each segment. Thus, option "B" is correct.

What is an earthworm's body plan?

The physique of the earthworm is segmented which appears like numerous tiny rings combined or merged collectively. The earthworm is made of around 100-150 segments. The segmented body portions deliver significant organizational purposes.

Segmentation can help the earthworm move. Each segment or piece has muscles and bristles named setae. The bristles or setae support the anchor and govern the worm when stirring over the soil. The bristles grasp a segment of the worm definitely into the ground while the other portion of the physique projects forward.

The earthworm uses parts to either contract or relaxes self-sufficiently to source the body to grow in one area or contract in other areas. The division supports the worm to be supple and sturdy in its drive. If each section stimulated collectively deprived of being self-governing, the earthworm would be stationary.

Thus, option "B" is correct.
