Every DNA strand has an EQUAL number of adenine and thymine nucleotides in a molecule. Explain why.
Answer:
Explanation: In other words, adenine and thymine are complementary base pairs, and cytosine and guanine are also complementary base pairs. This is the basis for Chargaff's rule; because of their complementarity, there is as much adenine as thymine in a DNA molecule and as much guanine as cytosine.

Africa and South America are 4,000 km apart. If the plates move away from each other at a rate of 30 km per 1 million years, how long would it take for them to travel 4,000 km?
Rate = Distance ÷ Time Distance = Rate ÷ Time Time = Distance ÷ Rate
The subject is science I just cant find it-
Answer:
The majority of the research shows that the plates move at the average rate of between approximately 0.60 cm/yr to 10 cm/yr. Some sources state that in the North Atlantic, the rate of movement is only about 1 cm (about 0.4 in) per year, while in the Pacific it amounts to more than 4 cm (almost 2 in) annually, while others say that plates, in general, travel from 5 to 10 cm/yr.

The Eurasian Plate is moving away from the North American Plate at a rate the is about 3cm per year. That is about the same rate at which your fingernails will grow.
