The correct answer is the type and sequence of molecules along each strand.
The DNA is formed of molecules known as nucleotides. Each nucleotide comprises a sugar group, a phosphate group, and a nitrogenous base. The four kinds of nitrogen bases are thymine (T), adenine (A), cytosine (C), and uracil (U). The order of these bases is what that determines the genetic code or the DNA instructions.

Answer: Option C.
Population density is the total number of organisms within a fixed area.

Answer:
all of them apply
Explanation:
In my opinion all of them apply (except the 4th one). Ecosystems can be small, big, have living and non-living parts and they are made of biomes. Not only can ecosystems vary in size, but they can also differ in just about every imaginable biotic or abiotic feature.
