Answer:

B. China's population is the largest in the world.

Explanation:

    Mandarin, also known as traditional Chinese, is the name given to a set of Chinese dialects spoken in central, northern and southwestern China. It is the main dialect spoken in China with approximately 845 million speakers (first language). It is also the most widely spoken language in the world.

Answer:

The struggling German economy was the largest contributing factor to the rise of the theory of eugenics in the 1930s. Germany faced enormous debt, widespread inflation, and massive unemployment. In this economic climate, people with physical and mental illnesses were viewed as a burden to the "healthy" population who made greater economic contributions. Therefore, both the Weimar Republic and the Nazi regime pursued a policy informed by the theory of eugenics, the belief that the development of the human race can be controlled by selective breeding. Their goals were to prevent illnesses from being passed on to future generations and to create a more economically robust workforce. The Nazi regime pursued a more aggressive version of this policy by mandating sterilization. The Weimar Republic, which had preceded them, sterilized people on a voluntary basis only.

An axiomatic system consists of some indistinct terms (primitive terms) and a listing of statements, called axioms or postulates, concerning the indistinct terms. One receives a mathematical theory by establishing new observations, called theorems, using only the axioms (postulates), logic system, and previous theorems.

Protecting the Earth's resources is crucial for maintaining the delicate balance of our planet's ecosystems, ensuring the survival of all species, and securing a sustainable future for humanity.

i took da test

Answer:

D. It provides nutrients to crops.

Explanation:

Water depth from sonar sounding with 5-second travel time: 7535 meters (24,721 feet).

To find the water depth using the total travel time of a sonar sounding, we'll use the formula:

[tex]\[ \text{Distance} = \text{speed} \times \text{time} \][/tex]

Given:

- Speed of sound in water: 1507 meters/second

- Total travel time of sonar sounding: 5 seconds

We can plug in these values into the formula to find the water depth:

[tex]\[ \text{Distance} = 1507 \times 5 \][/tex]

[tex]\[ \text{Distance} = 7535 \text{ meters} \][/tex]

So, the water depth is 7535 meters.

Therefore, the correct answer is: [tex]\[ 7535 \text{ meters (24,721 feet)} \][/tex]

The Olympic Games originated with the ancient Greeks, starting in 776 BCE at Olympia. The games were a significant cultural event for the Greeks, lasting over 1,000 years and enjoying participation from all Greek settlements. They ended in 393 CE when they were halted by the Roman emperor Theodosius.

The Olympic Games began with the ancient Greeks. The beginning of the Olympic Games dates back to 776 BCE, and these games took place at Olympia in southern Greece every four years, marking a significant event not only in sports history but also in the cultural identity of the Greek civilization. These games stood out due to their extraordinary longevity, lasting for over a millennium, and the broad participation of Greeks from various regions, including Sicily and the Black Sea.

As competitors came from all parts of the Greek world, the Olympics served as a unifying event that transcended city-states and regional identities. Despite the fierce competition where there were no second prizes, the Olympic Games were a time when wars were temporarily suspended, ensuring safe passage for athletes to participate in events dedicated to Zeus, the chief Greek god.

It is also worth noting that unlike the inclusive nature of the modern Olympic Games, ancient Olympic events were forbidden to women, and attendance was free only for men. The games continued until they were halted by the Roman emperor Theodosius in 393 CE due to the rise of Christianity.

In California, the elevations between the fog line and the snow line range from 2,000 to 10,000 feet. Temperatures decrease approximately 3.6°F for every 1,000 feet gained in elevation, contributing to significant temperature differences.

In California, the fog line is typically found at elevations below 2,000 feet and the snow line starts around 10,000 feet.. This is the area where moist air creates dense fog conditions, particularly along coastal regions. Moving higher in elevation, the snow line often starts around 10,000 feet in elevation, which varies depending on the specific mountain range and seasonal conditions.

It is within this range that you will experience significant temperature changes due to the environmental lapse rate, which is about 3.6°F decrease for every 1,000 feet gained in elevation.

For example, if you start at 3,500 feet with a temperature of 67°F, by the time you reach 14,000 feet, it would be approximately 29°F. This dramatic change helps maintain snowcaps on high mountains such as those in the Sierra Nevada range.

Here's a brief overview:

Fog Line: Up to 2,000 feet

Zone between Fog Line and Snow Line: 2,000 to 10,000 feet

Snow Line: Above 10,000 feet

Answer:

Coal : fossil fuel

Hydroelectricity : uses dams

Nuclear : creates toxic waste

Ethanol : made from recently grown plant matter

Explanation: APEX

Final answer:

Coal matches with fossil fuel as it is a type of fossil fuel. Hydroelectricity is characterized by the use of dams. Nuclear energy is associated with the creation of toxic waste due to spent fuel storage, and Ethanol is made from recently grown plant matter.

Explanation:

The question requires matching an energy source with its characteristic. The matchings are:

Coal is indeed a fossil fuel, derived from ancient organic material. Hydroelectricity is harnessed using dams that capture the energy from flowing water.

Nuclear energy relies on the process of nuclear fission, and though it does not produce carbon emissions, it does create toxic waste that must be carefully stored for long periods. Ethanol is a biofuel, often made from corn or sugarcane, which is plant matter that has been recently grown.
