Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
As humans travel in space, which gas is provided in the atmosphere of the spacecraft and which gas is removed from the atmosphere of the spacecraft?
A
Oxygen is provided. Carbon dioxide is removed.
B
Carbon dioxide is provided. Oxygen is removed.
C
Carbon dioxide is provided. Nitrogen is removed.
D
Oxygen is provided. Nitrogen is removed.
Explanation: 

Detailed explanation-1: -A majority of the breathing air for astronauts is recycled within the spacecraft or habitat, and a key part of this process is the removal of exhaled carbon dioxide.

Detailed explanation-2: -When astronauts aboard the International Space Station (ISS) exhale carbon dioxide (CO2), it’s removed from the air and pumped into space.

Detailed explanation-3: -The ISS has both tanked air stores and separate supplies of oxygen and nitrogen, while the Shuttle uses cryogenically stored oxygen and nitrogen. The gases are added to the atmosphere to replace leaks (no spacecraft is entirely free from leaks) or consumed oxygen.

Detailed explanation-4: -Oxygen is provided. Carbon dioxide is removed.

Detailed explanation-5: -The oxygen and nitrogen are mixed into the capsule for the astronauts to breathe.

Detailed explanation-6: -Most of the station’s oxygen will come from a process called “electrolysis, ‘’ which uses electricity from the ISS solar panels to split water into hydrogen gas and oxygen gas.

Detailed explanation-7: -It does not run out of oxygen. Its artificial atmosphere is a simulation of Earths which isnt pure oxygen, to stop anything as measly as a spark completely incinerating the whole station in flames. Anyway, there are constant resupply missions every now and then, coming up with food, water, and most importantly, air.
