1)Chargaff's rules state that DNA from any cell of any organisms should have a 1:1 ratio of pyrimidine and purine bases and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine. This pattern is found in both strands of the DNA.
2)DNA structure
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). The order of these bases is what determines DNA's instructions, or genetic code.
3)A nucleotide consists of three things: A nitrogenous base, which can be either adenine, guanine, cytosine, or thymine (in the case of RNA, thymine is replaced by uracil). A five-carbon sugar, called deoxyribose because it is lacking an oxygen group on one of its carbons. One or more phosphate groups.
4)DNA replication is said to be semi-conservative because of this process of replication, where the resulting double helix is composed of both an old strand and a new strand. ... Semiconservative replication would produce two copies that each contained one of the original strands and one new strand.
5)The diagram has show in above.
6)complementary base pairing is necessary because the double helix shape would not be the same if not. Doubles would only pair with doubles and the singles to singles.

Answer:
It should be change in behavior because they moved underground
Biological diversity. It studies all living organisms and how they interact with each other and their environment.
The Nucleus is separated from the cell’s cytoplasm by a
membrane. The nucleus contains hereditary materials made of plenty proteins and
DNA. The nucleus directs all cell activities. Nucleus is commonly found in
Eukaryotic cells. The genetic materials found in the Nucleus is organized as
DNA molecules, together with a wide array of proteins, which causes to form
chromosomes.
The correct answer for this question would be the third option. The statement that correctly compares the benefits of two forms of renewable energy is this: <span>Solar power and wind power are both clean energy sources. They are considered as clean and renewable energy because both are natural energy and are always available. Hope this answer helps</span>
