The Chemistry Of Biology
Chemistry in biology? Yikes! Can I do that?
In a simple answer? Yes.
What are the types of Bonds?
Macromolecules, Carbohydrates, Proteins and Fats. These are all part of the chemistry. Look to see more!

Let's start with the basics - What is an element?
What is an element? How many elements are there?
An element is a substance that is made entirely from one type of atom. For example, the element hydrogen is made from atoms containing a single proton and a single electron. If you change the number of protons an atom has, you change the type of element it is.
If you had very, very good eyes and could look at the atoms in a sample of hydrogen, you would notice that most of the hydrogen atoms would have no neutrons, some of them would have one neutron and a few of them would have two neutrons. These different versions of hydrogen are called isotopes. All isotopes of a particular element have the same number of protons, but have a different number of neutrons. If you change the number of neutrons an atom has, you make an isotope of that element.

What are the types of bonds?
Now that you know what an element is, you can understand that the elements form bonds to stay together or to form other compounds. There are multiple types! Click below to see what they are.
So why does ice float? Easy! DENSITY...

Ice has a very specific quality about it - it floats!
But why? In a word? Density. Density is the amount of mass in an object. I like to think of it as how tightly packed together something is. Density is all around us everyday and we hardly even realize it.
Think of the hallways during class - not that dense with students right? But as soon as the bell rings the hallways become dense with students!
Another example would be comparing notebook paper to construction paper. The construction paper is more dense than the notebook paper.
The examples go on and on... Think of the population on the South Pole compared to New York City -
Oil and vinegar salad dressing - Lead compared to cork -
Density mathematically speaking is mass divided by volume. That gives us the numeric calculation.
In science there are a few ways to look at it.
1. If water in the winter when it is cold enough to freeze sank instead of floated what would happen to the wildlife? Think about this for pond life, the ocean, even a puddle!
2. If the population is high (dense) of a specific parasite you can end up really sick! (one or two ecoli bacteria your body can kill but one or two THOUSAND is a whole bigger issue...
