During cellular respiration, our bodies take glucose molecules and breaks the bonds holding the molecules together. When these bonds are broken, the chemical energy stored in these bonds are released and used to make ATP molecules, a form of useable energy for us.
Answer:
Carbon dioxide is added to atmosphere naturally when organisms respire or decompose
Or through human activities, such as the burning of fossil fuels and forests and the production of cement.
A couple of things, if the shuttle burned all of it's fuel before entering Earth's atmosphere then that means that the shuttle was accelerating towards Earth until it ran out of fuel. At that point, there is little to no air resistance (friction) by the lack of an atmosphere so it keeps accelerating due to Earth's gravitational force. The closer the shuttle gets to Earth the stronger the gravitational pull the shuttle experiences. Note that, once the shuttle reaches Earth's atmosphere it will cause significant amount of friction and thus will cause the shuttle to slow down.
If the element's atomic mass is accurate enough you should be able to tell from that , however if it isn't you would most likely want the number of neutrons or electrons contained by the atom.
Hello There!
Well, technically no. It has to be one or the other, it can't be both.
Hope This Helps You!
Good Luck :)
