Answer:
Stereo microscopes, also called low-power microscopes, dissection microscopes, or inspection microscopes, are designed for viewing "large" objects that are visible to the naked eye at low magnifications (under 50x).

Explanation:
Answer:
First case:
C -> 30% and T -> 20%
Second case:
C -> 15% and T -> 35%
Explanation:
First of all you should know that if it is DNA, it's formed by two strands. Also, in DNA, the amount of A is the same as the amount of T. And the amount of C is the same amount of G.
So, if you have 20% of A, you will also have 20% of T.
And if you have 30% of G you will have 30% of C
I hope it's useful and that you understand it!
