The important role of the atmosphere is to supply oxygen, water, carbon dioxide and nutrients. It also protects all living things from extreme temperatures and radiation (protects us from harmful solar rays).
AIDS attacks white blood cells, damaging the immune system and making the infected individual more susceptible to illness. White blood cells are the ones that fight off harmful bacteria, so without them you could even end up in the hospital or die from a common cold.
Answer:
the growth rate of each of the plants/ the relative humidity inside each terrarium
Hello!

The big bang is a bit complicated.
Now, Kurzgesagt does an amazing video on this (and yes, I know mods dont like links very much) : https://www.youtube.com/watch?v=wNDGgL73ihY
I will explain as best I can. So, lets assume that the big bang theory actually happened for right now before any debates arise. First of all, we have no clue what even started it. There are so many theories as to why it started and was their a universe before the big bang.
Now, this is the interesting part. Every universe has its own laws. We have four laws or forces in ours that we know of (and then we have quantum physics which completely messes with physics but we wont get into that).
The Force of Gravity
The Strong Force
The Weak Force
The <span>Electromagnetic Force

We have no clue if there are any other universes and if they are, do they have different properties. If so, chemical bonding could be completely different.
So much could be different.
Now, we know there are also some laws like conservation of energy and law of balance. Balance is what made the universe. Atoms had to find their "mate" lets just say and create chemicals. These chemicals would then go on to bind more and more and create other things over time as the universe was also expanding.
The universe is still expanding (and even accelerating its expansion).
Things must be chemically stable and thats how bonds are formed.
Now, this also kinda opens up "why" and science does not always answer "why". Thats more for religion or philosophy.
Its very interesting and I suggest you look into the video I linked.
Hope this helps
