Answer:
Change in food source.
Explanation:
If there is a change in food source, then the organism will have to adapt to that change. For example, with Darwin's Theory on the finches on the Galapagos Islands. There were many different varieties from different size to different beaks. This was because of changes on food sources and they adapted to obtain them more.
Properties of minerals range from hardness to cleavage to color.
Quartz can be identified in that it has no cleavage, only fractures.
Calcite can be identified with a hardness of 3.
Topaz can be identified with a hardness of 8.
Fluorite can be identified as one of the only common minerals with 4 directions of perfect cleavage.
In a normal human karyotype, depending on the part of mitosis the cell is in, there are either 23 or 46.
<span>Kidneys
When you digest a protein, the body breaks down the protein into amino acids which the body then uses to build new proteins. But if there is an excess of amino acids, the body isn't capable of storing those excess amino acids for future use. So the body breaks down the amino acids into glucose, ketones, hydrocarbons and nitrogenous waste. The nitrogenous wastes are then converted to urea by the liver and the urea is extracted from the blood stream by the kidneys and expelled from the body.</span>
