I believe that the answer to this question is, that laws can be made to prevent certain things/ amounts of things to be used up.
There are 11 organelles in total,
vacuoles: they store water
Chloroplasts: trap energy from the sun to produce food for plant cell
Cell wall: provides support and protection to the cell membrane,
Cell membrane: thin flexible barrier around a cell, controls what enters/ leaves the cell
Nucleus: 'The control center', carries the DNA of the cell
Ribosomes: Found in all cells, their jobs are to make protein
Endoplasmic Reticulum: The internal delivery system of the cell
Golgi complex: Transports materials throughout the cell
Lysosomes: Break down food into particles the cell can use. another function is they destroy old or dying cells
Mitochondria: Breaks down food to make ATP
and last but not least cytoplasm a jelly like fluid in the cell that keeps the organelles suspended
If I recall correctly, I was taught:
The particles in the air (dust, smoke, etc.) increase in density the farther you look. Causing a "fog" effect as you look across large distances. Including shore to shore of an ocean.
Athletics would be the easiest choice here
Sports are an active that takes up a lot of different organ systems. When running I use my muscular system and cardiovascular system the most. The cardiovascular system directly controls running because it helps prevent me from getting tired and worn out faster.
Hope this helps :)
