Explanation: DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C).
Answer;
-5.83 AU
Explanation;
A year is defined as the time it takes a planet to complete one revolution of the Sun, for Earth this is just over 365 days. This is also known as the orbital period. Unsurprisingly the the length of each planet’s year correlates with its distance from the Sun.
Using the equation;
t² = a³
t = 3.24 years, the time it takes the planet to orbit .
a (astronomical units) = 3.24 ^3/2
= 5.83 anatomical units (AU).
point B this is a topographic map the lines indicate the elevation of the area and B is at the lowest elevation which would be where the water would gather
