People do release carbon dioxide during respiration and gas exchange. But this does not make a great amount of that plus, the plants requires them for photosynthesis.
However, nowadays people release a large amount of carbon dioxide into the atmosphere due to the operation of factories, and driving cars. The burning of fossil fuels, which generates electricity, is the main reason of the increasing carbon dioxide in atmosphere.
This can lead to greenhouse effect, since carbon dioxide can trap heat inside and still absorb more heat at the same time. And then, global warming occurs and it affects living organisms.
A closed loop system is one where the ouput of the system is at least part of the input. In a refrigerator, the output of the cooling system (the cold air inside the refrigerator) is measured, and is fed back into the system to determine whether the system needs to continue cooling.
<span>An example of a fridge that was an open loop system would be one that turns on and cools for 1 hour every 6 hours, regardless of internal temperature.</span>
Explanation:
The planet Mars has two moons. Phobos and Delmos (i) phobos has period `7` hours, `39` minutes and an orbital radius of `9.4 xx 10^(3) km`. Calculate the mass of Mars. (ii) Assume that Earth and mars move in a circular orbit around the sun, with the martian orbit being `1.52` times the orbital radius of the Earth. What is the length of the martian year in days? `(G = 6.67 xx 10^(-11) Nm^(2) kg^(-2))`
I don't quite understand the question but if it's a "complete the sentence" then the atomic number is the number of protons or electrons present in an atom.
