Answer:
chemical property
Explanation:
Wood is a flammable substance. Depending how dry it is will determine its flammability or what temperature it will burst into flame. Burning wood undergoes chemical property changes: the brown hard wood becomes a black pile of ashes.
C. Viral Hemorrhagic Fever is a form of marburg virus
A water molecule consists of two atoms of hydrogen linked by covalent bonds to the same atom of oxygen. Atoms of oxygen are electronegative and attract the shared electrons in their covalent bonds.
The decay of uranium isotopes is used to provide information about the age of Earth.
<h3>
Explanation:</h3>
Isotopes of Uranium U-232, U-233 , U-234 , U-235 , U-236 , U-238 are used as fuel in nuclear reactors or as explosives for nuclear weapons. Uranium 238 is not very radioactive and it constitutes for nearly 99.3% of natural uranium on Earth and has the longest lifetime: its period is 4.5 billion years, about the age of Earth.
Use of radiometric dating techniques help in defining the age of substances (natural or man-made) using the known decay rates of radioactive elements. Each element has an individual decay rate and half life time.
Two Uranium isotopes (U-238 and U-235) are used for radiometric dating. Both the isotopes have different decay rates and half life period. Both are unstable and radioactive. Since two different isotopes produce two different decay clocks (one as a reference to other), it is beneficial in accurately determining the age of samples. The age of earth (rocks or other natural elements) can be easily determined using Uranium isotopes.
The Mungo Man was discovered by ANU archaeologist Dr. Jim Bowler on ... This made Mungo Lady the oldest cremated human remains yet discovered.Thorne claims that the findings support his theoretical point of view.Evidence - Mungo Man's skull.Two years ago Thorne made world headlines with a study of Mungo Man's DNA that he had found.
