Coldest planet is Uranus 👍🏻 Not Mercury. Thanks

[@MasterChallenge_7]

Thank you for mentioning that! It's a mistake. Actually, Neptune is considered the coldest planet in the solar system, not Uranus or Mercury. Uranus is also quite cold, but Neptune's distance from the Sun makes it slightly colder overall. I appreciate your input though!

Q3, We inhale ALL gasses during inhalation, not just Oxygen. Very misleading.

[@MasterChallenge_7]

Thank you for pointing that out! You're absolutely right but oxygen is the correct answer, as it is the essential gas used by our body in the process of respiration. While we inhale a mixture of gases, oxygen is the one utilized in cellular respiration.
