Your paper should answer questions such as these: What was the scientist's early life like? What was the scientist's personality like? Did any world events affect the scientist? If yes, what were those events? Did the scientist have to overcome any obstacles to become a scientist? If yes, what were those obstacles? In what way did the scientist investigate the atom? Did the scientist use an observational study, a controlled experiment, or a mathematical model? What new understanding did the scientist achieve that resulted in an update to the atomic model? Which scientist will you write about? Explain why you made that choice.

enhanced global partnerships and exploration capabilities may advance international preparedness for protecting the earth from catastrophic events such as some asteroid strikes, advancing collaborative research on space weather and protecting spacecraft by developing new means for space debris removal.

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.
