<h2>Answer with Explanation </h2>

A scientific argument is known as people fail to agree about scientific claims using experimental data to prove their arguments. It is used by scientist to complete their research activities. Before developing an argument scientist need to look at the authenticity of the data, declarations, supposition or proposed explanation made on the basis of limited evidence and observations. These arguments are based on the proofs that are present. Therefore, they make sure that they are verified.

Analyze the data about nitrogenous base content of DNA from various species. Percentages of Bases in Five Organisms Source of DN

Troyanec [42]

Answer:

When analyzing data on the nitrogenous base content of the DNA of various species, the claims are supported by the data:

<em>In any one species, the amount of adenine closely approximates that of thymine. </em>
<em>In any one species, the amount of guanine closely approximates that of cytosine. </em>
<em>The amounts of A, T, G, and C in DNA varies from species to species. </em>

<em>(options A, B and D)</em>

Explanation:

Organizing the data has to:

<u>Source of DNA A T G C </u>

Streptococcus 29.8 31.6 20.5 18.0

Yeast 31.3 32.9 18.7 17.1

Herring 27.8 27.5 22.2 22.6

Human 30.9 29.4 19.9 19.8

E. Coli 24.7 23.6 26.0 25.7

DNA is the molecule that contains the genetic information of each species, formed by sequences of nitrogenous bases Adenine, Thymine, Cytosine and Guanine.

Since Adenine and Thymine -as well as Cytosine and Guanina- are complementary, the percentage of them will be very similar in each DNA molecule.

The genetic information -which determines the physical and functional characteristics of each organism- is encoded in the DNA and is different for each species, so the percentages of nitrogenous bases vary from species to species.

A complex assemblage of animals, plants, and their environment through which materials and energy move is known as?

kobusy [5.1K]

A complex assemblage of animals, plants, and their environment through which materials and energy move is known as ecosystem.

<h3>What is a ecosystem?</h3>

All the organisms that live in an ecosystem are present, along with their physical surroundings. Through energy flows and nutrient cycles, these biotic and abiotic components are interconnected. Plant tissue absorbs energy from the system through photosynthesis. Animals contribute significantly to the flow of matter and energy through the system by eating plants and one another as well as.

Additionally, they affect the biomass levels of the microbial and plant communities. Decomposers help to promote nutrient cycling by transforming nutrients stored in dead biomass back into a form that can be easily utilized by plants and microbes. They do this by consuming dead organic matter and releasing carbon back into the atmosphere.
