Summary
China
Area of Science:
- Environmental Science
- Resource Economics
- Industrial Ecology
Background:
- Consumption drives natural resource extraction and allocation.
- Understanding demand-driven resource requirements is crucial for sustainable development.
- Regional disparities in China's economic development impact resource use.
Purpose of the Study:
- To investigate demand-driven natural resource requirements and spatial outsourcing in China in 2012.
- To analyze the flow of embodied resources between Chinese regions.
- To quantify regional resource footprints and their implications.
Main Methods:
- Utilized a multi-regional input-output model.
- Employed exergy as a common metric for natural resource input.
- Analyzed embodied resource use (ERU) and direct resource input (DRI) across regions.
Main Results:
- Total domestic resource exergy requirements were 125.5 EJ, with the eastern area having the largest share (44.5%).
- Investment was the leading final demand, accounting for 52.9% of national embodied resource use.
- Significant spatial outsourcing of embodied resources occurred from central and western regions to eastern regions.
Conclusions:
- Regional uneven development leads to imbalanced resource requirements in China.
- Findings offer insights into China's resource-driven economic model.
- The study contributes to reducing regional resource footprints and environmental outcomes.

02:12Short-distance Transport of Resources
17.7K
Short-distance transport refers to transport that occurs over a distance of just 2-3 cells, crossing the plasma membrane in the process. Small uncharged molecules, such as oxygen, carbon dioxide, and water, can diffuse across the plasma membrane on their own. In contrast, ions and larger molecules require the assistance of transport proteins due to their charge or size. Transport across membranes also occurs within individual cells, playing a variety of essential roles for the plant as a whole.

01:32What is Natural Selection?
129.5K
Natural selection is an evolutionary process in which individuals with survival-promoting traits reproduce at higher rates. These favorable traits become more common within a population or species. Naturally selected traits initially arise via random genetic mutations. In order for selection to occur, there must be variation within a population, the trait controlling the variation must be heritable, and there must be an evolutionary advantage for variation in the trait.

The Earth and its atmosphere have provided humans with air, water, and food, but these are not the only requirements for survival. Humans also require a specific range of temperature and pressure that the Earth and its atmosphere provides.
Oxygen
Atmospheric air is only about 20 percent oxygen, but that oxygen is a key component of the chemical reactions that keep the body alive, including the reactions that produce ATP. Brain cells are susceptible to a lack of oxygen because they require a...

01:10Nature and Nurture
22.4K
Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...

01:28Proteins: Dietary Sources and Requirements
1.8K
Consuming animal-based products offers high-quality proteins that contain optimal levels and combinations of essential amino acids, crucial for tissue repair and growth. Foods like eggs, milk, fish, and most meats are a source of complete proteins. Legumes and cereals are abundant in proteins; however, they typically lack a full range of essential amino acids. As a result, they are considered incomplete protein sources. Some plant sources like soybeans, quinoa, and amaranth do contain complete...

Microorganisms exhibit diverse oxygen requirements and growth patterns driven by their metabolic strategies and environmental adaptations. Oxygen, while essential for many organisms, can also be toxic under certain conditions, shaping how microorganisms grow and survive.Oxygen Requirements of MicroorganismsMicroorganisms are classified based on their ability to use or tolerate oxygen:● Obligate aerobes like Mycobacterium tuberculosis need oxygen for energy production, as it serves as the...
