The first gap is phosphate sugar skeleton

The second gap is  nitrogenous bases .

The third gap is  nitrogenous base too, found only in RNA.


The skeleton of DNA is the phosphate-sugar succession of which each sugar bears a nitrogenous base.

Nitrogen bases are nitrogenous organic compounds present in nucleic acids in the form of nucleotides in which they are linked to a sugar.

The five main bases are adenine, cytosine, guanine, thymine and uracil.

A sugar-phosphate backbone (alternating grey-dark grey) joins together nucleotides in a DNA sequence. The sugar-phosphate backbone forms the structural framework of nucleic acids, including DNA and RNA. This backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.The two strands run in opposite directions, one going in a 3' to 5' direction and the other going in a 5' to 3' direction. The nitrogenous bases are positioned inside the helix structure like "rungs on a ladder," due to the hydrophobic effect, and stabilized by hydrogen bonding. Uracil is one of the four nucleobases in the nucleic acid of RNA that are represented by the letters A, G, C and U. The others are adenine, cytosine, and guanine. In RNA, uracil binds to adenine via two hydrogen bonds. In DNA, the uracil nucleobase is replaced by thymine. Uracil is a demethylated form of thymine.

hope this helps

1. What is the scientific method? Is there just one universal scientific method? Why or why
natulia [17]

Answer:

Follows are the solution to this question:

Explanation:

1)

Its scientific process explains how researchers obtain worldwide knowledge. 6 key elements define this method: queries, assumptions, experiments, observations, evaluation, and results. It is interconnected measures, however, that they should not operate in the same sequence often.

2)

It is about learning and describing as just a collective body, Science aims to give an ever more rigorous explanation of the workings of a natural environment, its elements as well as how the country now should be.

3)

Science will help to create the latest knowledge in solving practical problems and determine personally and mutually responsible choices.

4)

Science will allow the intellect to develop new information and also to overcome the excitement on how today's world is developing and functioning. Science was important because it helped to shape the world wherein we live today.

5)

It can write credibility through the use of reliable information to back up your argument in your research. High-quality resources that support your arguments will more frequently lead to better outcomes for the tasks. Its use of reliable sources can help as a topic.

6)

The peer-review will also include subjecting of its author's empirical research and research into another relevance and suitabilities to review by other experts in the same field. Its author should decide if a work is acceptable via a peer review.

7)

Knowledge in which observations are only based on what can be observed directly may help students to learn how science can infer. It can help students to understand why scientists utilize facts in responding to questions by distinguishing among observations and assumptions.

8)

Other components are kept similar by constant. Control systems have such preferential privileges for a single group, whereas the group doesn't seem to.  

9)

In seeing what occurs if you adjust the factor to also be tested you can equate the results of the experimental groups with those of the human rights group. The treatment group is also an integral part of a study because it allows everyone to be removed and separated.

The relationship between the bacterium Xenorhabdus nematophila and its nematode host, Steinernema carpocapsae, is classified as
Cloud [144]

Answer:

The correct answer will be-cooperate

Explanation:

Nematodes or ringworms interact with the bacteria in one of three ways: mutualism, parasitism and symbiosis.

The interaction between nematode <em>Steinernema carpocapsae</em> and bacteria  <em>Xenorhabdus nematophila</em> prove to be a symbiotic relationship as both the organisms benefit each other.

The interaction between these two organisms is also known as cooperation because both the species can live without each other also. It is during the infective juvenile stage, the bacteria start living in the intestine of the nematode and benefiting the nematode. Both bacteria and nematode help each other killing the host and then utilizing the cadaver of the host.

Thus, cooperate is the correct answer.
