1. Maintaining a specific internal pH is a form of homeostasis, or
keeping the body's systems in balance. Homeostasis is a dynamic rather than
static process in that it is "continuously adjusted in response to changes
in the internal or external environment" ("Maintaining an Internal
Balance"). These changes in the environment can include extreme
temperatures, exercise, fatigue or infection.
Biological organisms must maintain a specific balance between acids and bases/alkalines in order to survive. For humans, the ideal blood pH leans toward the alkaline side at 7.3 to 7.4. All of the body's metabolic reactions depend on the pH; these processes only operate successfully within a narrow range of pH, between 7.36 and 7.44. Only in this pH range does the blood have an ideal supply of oxygen. If the blood pH goes over 7.44, then the risk of developing degenerative conditions increases. A lot of factors can affect the pH level of our blood: stress, our diet, pollution are three factors. If the body can't maintain the ideal Ph pollution are three factors. If the body can't maintain the ideal pH balance, it will start to break down and die - thus, the body is constantly trying to maintain this ideal balance ("pH Balance").

this question: What does the body use cholesterol
for? Testosterone? What are some other types of natural steroids?
3.Carbon is a very useful atom in
creating organic compounds because its four valence electrons like to form
bonds with other elements in a multitude of ways. Carbon atoms have the ability
to form covalent bonds with many different atoms, "...carbon atoms combine with one another indefinitely to
give compounds of extremely high molecular weight, but the molecules formed can
exist in an infinite variety of three-dimensional structures. The possibilities
for diversity are increased by the presence of atoms other than carbon in
organic compounds, especially hydrogen (H), oxygen (O), nitrogen (N), halogens (fluorine [F], chlorine [Cl],bromine [Br],
and iodine ),
and sulfur (S)."

Allotropes - different forms - of carbon are common, the most common of which is graphite ("Web Elements ", 2012). The most common form of graphite is alpha graphite, its structure is composed of one carbon atom bonded to three other carbon atoms in a layer structure with shorter than normal (carbon to non carbon) bonds ("Web Elements ", 2012). Graphite, along with diamond, which we will discuss below, are examples of infinite latices meaning the layers go on forever, whereas a new form of carbon allotrope, called fullerenes are finite structures bonded in a spherical shape. ("Web Elements ", 2012)
We all know the carbon allotrope diamond, it is less common than graphite. Although graphite can be transformed into diamond with great amounts of heat and pressure ("Web Elements ", 2012). We usually see clear diamonds, but more rare are the pink, blue and yellow forms. According to Jeffrey Post curator of the National Gem and Mineral Collection, colored diamonds arise from impurities in the structure of the diamond. When we see a blue diamond - the most rare - a bit of boron takes the place of carbon in some bonds, yellow is caused by nitrogen being trapped in the structure, green is thought to be caused by radiation from the surrounding rock causing imperfections in the carbon structure, reddish and pink diamonds are thought to be caused by electrons blasting the structure on their tumultuous journey through tectonic forces to the surface, causing light to be refracted differently (Lineberry, 2007). My favorite diamond color is probably a bright yellow, they are beautiful and very expensive.
It is difficult to choose a favorite carbon compound, there are so many good ones, but if I had to choose I would probably choose an organic compound of some sort due to their amazing capabilities inside our bodies.
