Given what we know, we can confirm that statement 1 is false, while statement 2 is in fact true. Option D is correct.
<h3>Why is statement 1 false and 2 is true?</h3>
Statement 1 states that the melting point of DNA is determined by the denaturalization of 50% of the double helices in the sample. This is not the case, since the DNA melting point is when 50% of the sample becomes single-standard DNA. Statement 2 is true in that a higher concentration of GC base pairs leads to a higher melting point for DNA.
Therefore, we can confirm that statement 1 is false, while statement 2 is in fact true. Option D is correct.

Answer: A correlation is a measure or degree of relationship between two variables. A set of data can be positively correlated, negatively correlated or not correlated at all. As one set of values increases the other set tends to increase then it is called a positive correlation.

The hypothesis is
<span>If more dry cells are connected end to end, a light bulb will work longer because there is more energy available.
The variables are
the number of dry cells connected end to end
the duration of the light bulb working</span><span />
