Which factors affect a rivers load

2 answers:

4 0

To answer the question that is: "which factors affect a river's load", we have to understand that all the things mentioned are important. All these options (river's slope, streambed shape and volume of flow) affect the amount of energy that the river has to spend and the way the river spend that energy, so, it is right to mark the alternative d) all of the above.

DNA replication is Group of answer choices conservative. a one-step process. semi-conservative. not carried out by enzymes. not

Alex787 [66]

Answer:

The correct answer is: semi-conservative.

Explanation:

DNA replication is an important process in which the DNA is duplicated before cell division so each daughter cell can have a copy of genetic material.

DNA replication is semi-conservative because one strand of DNA is new and the other one is the old strand. To replicate itself, the DNA double helix is opened, and then each strand serves as a model for the new strands.

DNA replication is not a one-step process, as it takes several complicated steps in which lots on enzymes participate (like DNA polymerase and DNA helicase).

DNA replication is also carried by prokaryotic cells, though it's a much simpler process.

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.

Now that you have come up with an equation that describes the relationship between amounts of different nucleotide bases in DNA,

Colt1911 [192]

Answer:

G=21 %

T= 29 %

A= 29 %

Explanation:

Since C only binds to G, you have the same amount of C and G, so G is 21 %.

100 % minus 42 % ( 21 % C plus 21 % G=) equals 58 %.

So the other 58 % is made of T and A. Since T only binds to A , the half of the extra 58 % is T and the other half is A. Therefore 29 % is T and 29 % is A
