The structure of cordycepin reveals that it lacks the ___________. This functional group is critical for addition of _______________ to the growing RNA chain, so after cordycepin is incorporated as a ribonucleoside ___________into the RNA chain, it prevents the further addition of ________.
The structure of cordycepin reveals that it lacks the 3' OH. This functional group is critical for addition of [ribonucleotides] to the growing RNA chain, so after cordycepin is incorporated as a ribonucleoside [monophosphate] into the RNA chain, it prevents the further addition of [ribonucleotides].
What is the role of ribonucleotides in transcription?Ribonucleotide-based mutagenesis requires two Top1 cleavage events on the same DNA strand and, in the context of transcription, modifications arise mainly when the enzyme cleaves the not-transcribed strand of the reporter.
Thus, 3' OHribonucleotides, monophosphate are the answer.

Every balanced chemical equation follows law of conservation of mass. This law states that mass can neither be created nor be destroyed but it ca only be transformed from one form to another form.
In a chemical reaction, total number of individual atoms on the reactant side must be equal to the total number of individual atoms on the product side.
During a chemical reaction, the atoms on the reactant side must also be present on the product side.
For the given reactants, the chemical equation will follows:
As, the reactant side contained carbon, hydrogen and oxygen atoms only. So, the product will also contain the same atoms.
the correct answer is Option B.

Deforestation is the clearing of Earth's forests on a massive scale, often resulting in damage to the quality of the land. Forests still cover about 30 percent of the world's land area, but swaths the size of Panama are lost each and every year. Deforestation on such a large scale has a dramatic effect on the carbon cycle. Which of the following describes the effect large scale forest clearing will have on the carbon cycle.
Answer: B
Explanation:
the less trees the more carbon
Large-scale forest clearing, such as deforestation, has a significant impact on the carbon cycle. The carbon cycle is the process by which carbon moves between the atmosphere, land, and oceans and is an important part of regulating the Earth's climate.
What is deforestation?Forests are important for the carbon cycle because they absorb carbon dioxide from the atmosphere during photosynthesis and store it in their biomass and in the soil. When forests are cleared or burned, the carbon stored in the trees and soil is released into the atmosphere as carbon dioxide, contributing to greenhouse gas emissions and climate change. In addition, deforestation can disrupt the water cycle, leading to changes in rainfall patterns and soil moisture
Hence, large-scale forest clearing, such as deforestation, has a significant impact on the carbon cycle. The carbon cycle is the process by which carbon moves between the atmosphere, land, and oceans and is an important part of regulating the Earth's climate.

Which cell helps to move dust particles out of an organism? A ciliated cell B guard cell c muscle cell D red blood cell
Answer:
A) A ciliated cell
The cells that help to move dust particles out of an organism are known as red blood cells. Thus, the correct option for this question is D.
What is the function of Red-blood cells?The function of Red blood cells is determined by the fact that they carry oxygen from our lungs to the rest of our bodies. Then they make the return trip, taking carbon dioxide back to our lungs to be exhaled.
The amount of carbon dioxide that is accumulated in the body of an individual may be said to be a waste product because it is usually formed as the byproduct of several metabolic processes. Apart from carbon dioxide other waste products may also form in the body which is moved out of organisms with the help of red blood cells.
