Introduction Magnets have existed for hundreds of thousands of years and have been used by many different cultures throughout this time. Magnets have been useful throughout the years because they can hold two things together just through the force of the metal in the magnet. With the world’s constantly changing technology, electromagnets have been evolved from magnets and are more useful than a regular magnet but in order for an electromagnet to work, an electric current needs to be present

Whether a material is magnetic depends on the material’s atoms”. A material’s atoms can effect what different materials that the magnet can pick up. Everything in the universe is made up of atoms and electrons. The electron moves around the atom and as it does this, it creates a magnetic field. In materials such as aluminum and copper, the magnetic fields of those certain atoms delete each other making the materials not magnetic. “In materials such as iron, nickel, and cobalt, groups of atoms are in tiny areas called domains. The north and south poles of the atoms in a domain line up and make a strong magnetic field. The arrangement of domains in an object determines whether the object is magnetic or not”. Because magnetic materials contain domains, this makes the material magnetic and attract other magnetic objects. What are the different kinds of magnets? Magnets are made up of many different materials such as “iron, nickel, cobalt, or a mixture of these metals”. Ferromagnets are created with those metals and produce strong magnetic properties. “A mineral magnetite is an example of a naturally occurring ferromagnet” from the combination of stronger metals. Another kind of magnet is the electromagnet. This kind of magnet is made from an electric current and an electromagnet consists of an iron core. Magnets can also be classified as

How do stabilizing and disruptive selection differ? see section 23.3 (page 463) . view available hint(s) how do stabilizing and
Contact [7]
The correct answer is stabilizing selection reduces the amount of variation in a trait. disruptive selection increases the amount of variation in a trait.

Stabilizing selection is a type of natural selection in which genetic diversity decreases because natural selection favours an average phenotype and selects against extreme variations.
<span>
Disruptive selection is a type of natural selection in which extreme values for a trait are favoured over intermediate values, thus it increases genetic variance.</span>
