What is living matter made up of?

Living organisms on Earth are made of a mixture of carbon, hydrogen, oxygen, nitrogen, sulfur, and phosphorous. This includes water, which has the chemical name H2O and contains two hydrogen and one oxygen atoms.

What elements make up Earth living matter oceans and atmosphere?

A limited number of elements, including, silicon, aluminum, iron, sodium, calcium, potassium, magnesium, hydrogen, oxygen, nitrogen, and carbon form the largest portion of the Earth’s crust, living matter, the oceans, and the atmosphere.

What are the 6 elements that make up living things?

Nonetheless, all organisms are built from the same six essential elemental ingredients: carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur (CHNOPS).

What are the 2 most common elements found in earth’s living matter?

Carbon, hydrogen, oxygen, and nitrogen are the most important elements. Small quantities of other elements are necessary for life. Carbon is the most abundant element in living matter. Nitrogen is continually re-circulated.

Will eating uranium kill you?

Because uranium decays by alpha particles, external exposure to uranium is not as dangerous as exposure to other radioactive elements because the skin will block the alpha particles. Ingestion of high concentrations of uranium, however, can cause severe health effects, such as cancer of the bone or liver.

How much plutonium is deadly?

Animal studies indicate that a few milligrams of plutonium per kilogram of tissue is a lethal dose. (30) by intravenous injection for an average human of 70 kilograms would be about 22 milligrams. By inhalation, the uptake would have to be about 4 times higher.

Can you survive polonium poisoning?

While radioactive, it emits a high-energy form of radiation, but the particles do not travel far and it decays relatively quickly. If polonium-210 enters the body, through inhalation, swallowing, broken skin, the results can be fatal.

Why do they use plutonium in bombs?

The isotopes uranium-235 and plutonium-239 were selected by the atomic scientists because they readily undergo fission. Fission occurs when a neutron strikes the nucleus of either isotope, splitting the nucleus into fragments and releasing a tremendous amount of energy.

What does a neutron bomb do to humans?

Upon detonation, a near-ground airburst of a 1 kiloton neutron bomb would produce a large blast wave and a powerful pulse of both thermal radiation and ionizing radiation in the form of fast (14.1 MeV) neutrons. The thermal pulse would cause third degree burns to unprotected skin out to approximately 500 meters.

Was nuking Japan a war crime?

Peter Kuznick, director of the Nuclear Studies Institute at American University, wrote of President Truman: “He knew he was beginning the process of annihilation of the species.” Kuznick said the atomic bombing of Japan “was not just a war crime; it was a crime against humanity.”

Was Pearl Harbor a war crime?

Japan and the United States were not then at war, although their conflicting interests were threatening to turn violent. The attack turned a dispute into a war; –Pearl Harbor was a crime because the Japanese struck first.
