2. This is because magnets attract materials that have unpaired electrons that spin in the same direction.

3. If you break a magnet length wise, they will not fit back together because the like poles repel.

4. Place light pressure on the magnet and rub the metal in one direction only. Magnetization will take some time to accomplish so continue rubbing until the iron or steel attracts other pieces of metal. Repeat the magnetization process, as necessary.

Charles Darwin’s theory of evolution as written in his book On the Origin of Species determined that In it, he proposed that species evolve and that all living things can trace their descent to a common ancestor.

Who was Charles Darwin?

"Charles Darwin, his full name was Charles Robert Darwin12 February 1809 – 19 April 1882) was an English naturalist, geologist and biologist, best known for his contributions to evolutionary biology. His proposition that all species of life have descended from a common ancestor is now widely accepted and considered a fundamental concept in science. In a joint publication with Alfred Russel Wallace, he introduced his scientific theory that this branching pattern of evolution resulted from a process that he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding."

What is species?

species means by itself is vague because it refers to the species concept, the species category and the species taxon, all of which are distinct although related to one another. The species concept is not primarily a part of systematics, but has always been an integral part of basic biological theory, It is based on evolutionary theory and applies only to s-exually reproducing organisms

You know I dislike slavery; and you fully admit the abstract wrong of it. So far there is no cause of difference. But you say that sooner than yield your legal right to the slave— especially at the bidding of those who are not themselves interested, you would see the Union dissolved. I am not aware that any one is bidding you to yield that right; very certainly I am not. I leave that matter entirely to yourself. I also acknowledge your rights and my obligations, under the constitution, in regard to your slaves. I confess I hate to see the poor creatures hunted down, and caught, and carried back to their stripes, and unrewarded toils; but I bite my lip and keep quiet. In 1841 you and I had together a tedious low-water trip, on a Steam Boat from Louisville to St. Louis. You may remember, as I well do, that from Louisville to the mouth of the Ohio there were, on board, ten or a dozen slaves, shackled together with irons. That sight was a continual torment to me; and I see something like it every time I touch the Ohio, or any other slaveborder. It is hardly fair to you to assume, that I have no interest in a thing which has, and continually exercises, the power of making me miserable. You ought rather to appreciate how much the great body of the Northern people do crucify their feelings, in order to maintain their loyalty to the constitution and the Union
