What Are Four Rules of Nature?

Question

Please, No religion.

Answer 1

What do you mean by rules of nature? Perhaps you could be more specific.

Answer 2

"Nature abhors a vacuum:"  living things fill everywhere on earth.

Life comes from pre-existing life:  life does not arise through spontaneous generation (the latter has never been observed).

Creatures give rise to their own kind.  There may be minor variations, but when creatures reproduce they make offspring of the same kind of creature as their parents.  

All living things eventually die.

Organisms are made of cells (either single-celled or multicelled).
