I'm dying (18 points) sorry if it's difficult to read, also i'll give !

I believe the diagram does not show the springs that are "in the ocean." Also, a "submarine spring" is included in the diagram, but the text does not mention it. 

It's a bit hard to make out the text in the diagram, but hat was all I was able to come up with. 

Okay, biology isn't exactly my strongest subject (it never has been), but i'm pretty sure the answer is nucleotides. dna is made up of nucleotides. each nucleotide contains a phosphate group, a sugar group, and a nitrogen base. there are four different nitrogen bases: adenine (a), thymine (t), guanine (g), and cytosine (c). a always pairs with t, and g always pairs with c.
