Darwin's evolution theory explains organisms change accordingly.
Explanation:
Darwin traveled the world sitting on a five year voyage , during his journey he collected various species of plants as well as animals. He also came across three different types of diversity that are globally, locally, species overtime. Darwin said as earth is an oldest planet various changes have occurred from and still going on in present. Darwin said Farmers choose organisms based on traits and humans choose base on their needs. Four things essential for natural selection are competition, adaptation, variation, fitness.
Microtubules are one of the cytoskeletal filament systems in eukaryotic cells. The microtubule cytoskeleton is involved in the transport of material within cells, carried out by motor proteins that move on the surface of the microtubule.

Mass does<span> not </span>affect<span> the </span>acceleration<span> due to gravity in any measurable way. The two quantities are independent of one another. Light </span>objects<span> accelerate more slowly than heavy </span>objects<span> only when forces other than gravity are also at work. When this happens, an </span>object<span> may be falling, but it is not in free fall.
Mass does matter when pointed in a downward angle, like if you have a metal toy car racing down a large peice of wood at a downward angle. If you had a plasitic car aong side it to measure which would go faster the metal car will reach the bottom quicker, gravity weighs down things :)</span>
