Answer:

Painted turtle often sits on log and basks in the sun in order to regulate its body temperature.

Explanation:

Painted turtles can be found in most part of North America. Painted turtles are cold blooded which means that unlike humans who are warm blooded beings and who can regulate their own body temperature, painted turtles are dependent on the outside surroundings to regulate their body temperature.

In order to get warmth and to balance their body temperature, painted turtles are often found sitting in the sun enjoying the heat mostly near the log or ponds. Compared to other turtle, painted turtles can stand the cold real well.

1. What are Chargaff's rules?

kotegsom [21]

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.
