Breaks down over time and becomes dirt
For evolution to occur:
There must be genetic variation in a population. This provides variation on which natural selection can act. Then natural selection can act by selecting those species which are better adapted to the environmental conditions. Over time those animals that are best suited to the environment only will survive and reproduce. Those organisms successful genes will be preserved and eventually the gene frequency in the population will change, changing the overall characteristics of a population. This is how evolution occurs.
The main term of reference in the index is Aneurysm
Extra cranial carotid artery aneurysms ruptures when the blood clots are formed in them. The term aneurysms is a disease that is happening due to the weakness in the wall of artery. The weakened arteries widens out or swells.
The sum of all the genes in a population is referred to as the gene pool.
A scientific model is a claim or a theory that helps explain how a phenomenon works or how it undergoes process. This models provides scientists an understanding of the object or a situation undergoes change and generate certain outcomes or effects.
