G pairs with C
A pairs with T

45 cytosines, 45 guanines
55 adenines, 55 thymines 
Cytosine pairs with Guanine, and Adenine pairs with Thymine.
This means, that if there are 45 cytosines, there must be 45 guanines.
So that's 90 base pairs down.
That means that there are 10 left between adenine and thymine- so that means there are 5 adenines.

Decreasing the saturation of the fatty acid chains on a particular type of phospholipid would result in the formation of _____.
Helga [31]

More fluid bilayers will be formed when the saturation of the fatty acids chains on a phospholipid is decreased.

Fatty acids are present in animals, plants and other microorganisms. They are composed of the carbon chain with carboxyl group at the end of the chain. The fatty acids are the vital components of the lipids, which are the essential fat soluble components. When the saturation level of these acids is decreased, it leads to the formation of more lipid bilayers.

Hence, the correct answer is 'more fluid bilayers'.
