These are nucleotides that have a single ring structure. Example: Cytosine, Thymine, and Uracil
IgorLugansk [536]

Answer:

The question is incomplete.

However, I notice that your question is mainly dealing with

"Nucleotides with a single ring structure"

I tackled that part, also providing explanation to the point you focused on.

Explanation:

Nucleotides are compounds in which nitrogenous bases (purines and pyrimidines) are conjugated to the pentose sugars (ribose or deoxyribose) and at least one phosphate group. Thus a nucleotide consists of a nitrogenous base, pentose sugar and at least one phosphate group.

Examples of the nitrogenous bases are Adenine, Guanine, Thymine, Uracil and Cytosine. Of all, Thymine, Uracil and Cytosine are with single ring, while Adenine and Guanine are double ring structure.

Simone is creating a model to track the movement of carbon atoms in an ecosystem. Which statement best explains the role of plan
Mademuasel [1]

Although I cannot see the model for Simone's experiment, I can offer the insight that the most likely role of plants in the model is that they consume the carbon atoms and produce oxygen.

<h3>How do plants affect the carbon in the atmosphere?</h3>
  • Plants are known to have a<u> great effect</u> on the carbon levels of the atmosphere.
  • The correlation is that the more plants are present, the less carbon is free in the air.
  • The reason for this is that plants use carbon dioxide as a substrate to manage the process of photosynthesis.
  • As a by-product, after consuming carbon dioxide and completing photosynthesis, plants release oxygen into the atmosphere.

Therefore, we can confirm that the most likely role of plants in the model created by Simone, is that they will consume carbon atoms in the form of carbon dioxide in order to sustain photosynthesis, which releases oxygen.

Scientists cannot define life, but they can list characteristics that are true of all life
pychu [463]
What are you asking for here? we need a solid question not a statement.

i'd say that the statement is true. we cant define life because we do not know what life, in essence, is. we can define, however, the characteristice of all living things:
Movement
Respiration
Sensitivity

Nutrition
Excretion
Reproduction
Growth

Which of the following is an enzyme required by the process of rephosphory,to create ATP? A) AD Pase B)AT Pase C)Polymerase D)AT
iren [92.7K]

ATPase is the enzyme which is required to create ATP and is denoted as option B.

<h3>What is ATPase?</h3>

This type of enzyme is found in the mitochondrion and catalyzes the formation of ATP which provides energy to cells.

The ATP which is referred to as adenosine triphosphate is formed from the molecules known as ADP and inorganic phosphate which are present in the body cells. This ensures that the daily energy needs of the body are met.

Intermediate photographs should show the relation of evidence to other parts of the crime scene. A. True B. False​
hichkok12 [17]

Answer:

True.

Explanation:

<em>"adjective </em>

<em>adjective: intermediate </em>

<em>coming between two things in time, place, order, character, etc."</em>

Pictures correlating to the crime scene are like puzzles to find out the other meanings or cause of another picture.

For example:

A opened jug of milk sits on a table.

There's a blurred figure of a hand hitting the jug.

The jug is now laying on the table, dripping everywhere.

-

If we take out the middle picture "There's a blurred figure of a hand hitting the jug.", then we would not know what hit it over. Did someone bump into the table? Did a cat climb onto the table and release its almighty strength onto it? All we would know that it was once standing upright.

TLDR; Without intermediate pictures, it would be hard to grasp what happened on the scene. Intermediate pictures all have something in common with each other to help interpret what occurred to the viewer.
