25 degrees Celsius, as this is the highest point on the graph which means that the oxygen flow is optimal at this temp. Since oxygen is a product of photosynthesis, if more is flowing at 25 degree, more photosynthesis is happening.
The answer is A as Adenine (A) pairs with Thymine (T) and Guanine (G) pairs with Cytosine (C)
What? the two terms are??
This is called an isotope.
