There are 15 base pairs in the strand.

Explanation:

A DNA is a double stranded helical molecule containing four different nitrogenous bases. The nitrogenous bases found in DNA are Adenine, Thymine, Cytosine and Guanine.

In the double stranded sequence above, a base in the first strand pairs with a base directly under it in the second strand. Thus, A pairs with T while G pairs with C. Each of the strands have 15 bases which represents 15 base pairs.

stratosphere: as the altitude increases, the air temperature increases. the stratosphere has a layer of ozone, called the ozone layer. this layer absorbs most of the ultraviolet radiation from sunlight. this results in the stratosphere being warmer.
