All of the above!
By analyzing the remains of fossilized organisms (such as old animal bones or plants), scientists can approximate what the organism might have looked like and the climate/environment it lived in -- and based on that, they can try to figure out how the Earth's surface has changed over time. Also, they can use the fossil to compare it to creatures that live now to see what has changed in that species over time.
Carbon-Oxygen
We breathe in oxygen, we breathe out carbon dioxide.
<h2>Answer:</h2>
D) The geosphere, hydrosphere, and atmosphere
<h2>Explanation:</h2>
During the carbon cycle, various processes move carbon from the geosphere to the atmosphere such as volcanic eruptions release carbon dioxide from molten rock beneath the earth's surface to the atmosphere. Carbon can leave the soil through soil respiration which releases CO2, or by erosion which can carry it into rivers or the ocean, where it then enters the hydrosphere. Carbon is found in the hydrosphere dissolved in ocean water and lakes and hence the cycle continues.
The moles of Al that are needed to react completely with 17 .5 moles of FeO is 11.67 moles
<u><em>calculation</em></u>
2Al +3 FeO → 3 Fe + Al₂O₃
The moles of Al is calculate using the mole ratio
That is; From equation above the mole ratio of Al :FeO is 2:3 therefore the moles of Al
= 17.5 moles x 2/3 = 11.67 moles
B
While nuclear energy does not pollute the environment, it poses the risk of radiation which is harmful to organisms because it causes lethal mutations.
Explanation:
Nuclear fission, for example, releases neutrons and other particles (at very high speeds) that can ionize materials including DNA. This will induce mutations of DNA most of which are usually lethal to organisms. Gamma and X- rays are also produced by fusion reactions and if exposed to organisms also cause mutations on DNA through double stranded breaks. Therefore, the risk of an accident of a nuclear reactor can have immense ramifications on the ecosystems.
