One reasonable plan would be to wear a face mask or surgical
mask. Take note that your surgical mask contains two sides – the white side and the
blue side. Since the main purpose of your mask usage is to prevent yourself
from inhaling too much bad air, the blue side of the mask should be the one
touching your skin. This is because the white side of your mask helps you
prevent from coming in contact with toxins that may come from the smog.

I had this question when I took a biology class cuz I chose to study a lot on paleontology :)
It’s that there’s fossils of animals in geological strata that are older than the Cambrian explosion.
Some fossils from the ediacaran period have been discovered in layers aged to the Cambrian
The particles that make up matter are the atoms.
Atoms do not change during a chemical change. They do not either during a physical change.
During a chemical change molecules change but not the atoms. The atoms separate from the original molecules and form new molecules. Then moleculas change but atoms remain being the same before and after the chemical change.
For example, atoms of oxygen in molecules of O2 combine with atoms of hydrogen in molecules of H2 and they form the molecules of water H2O.
The atoms of O in O2 are the same atoms of O in H2O and the atoms of H in H2 are the same atoms of H in H2O. The molecules changed, from H2 and O2 to H2O, but the atoms are the same.
