They are the same equation just reversed
Answer;
-Nucleotides
Explanation;
-Nucleic acids are polynucleotides, that is, long chainlike molecules composed of a series of nearly identical building blocks called nucleotides. Each nucleotide consists of a nitrogen-containing aromatic base attached to a pentose (five-carbon) sugar, which is in turn attached to a phosphate group.
-A sugar-phosphate backbone 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.
Answer:
Fossils plays an important role in the field of biological study. It is because it acts as key evidence for the evolution that has been occurring on earth since the time of origin of earth.
These fossils are valuable as they are found to be embedded in the sedimentary rocks of about millions and billions of years old. The study of these fossils enabled scientists to understand how life evolved from single-celled organisms to the present day complex organisms. The initially occurring organism was comparatively small and soft-bodied, and so are rarely found. But in today's world, the organisms existing are much different and structured in a well-defined pattern, and this helped in the understanding of the evolutionary pattern of life on earth and also explains the key factors that are responsible for the occurrence of evolution.
Thus, these fossils are considered to be very much essential for studying biological evolution.
Answer: Independent variable is the Vitamin C and the ashy skin is the dependent variable.
Explanation:
We can change or manipulate the independent variable of the reaction and such change can be observed on the dependent variable. The dependent variable yields the results of the experiment and changes in the dependent variable must be observed attentively to frame the results.
Here, vitamin C is the independent variable whose affect has to be observed on the ashy skin which is the dependent variable of the experiment. Steps of the experiment:
1. We can apply Vitamin C in a form of solution on the ashy skin.
2. Observe the changes on the skin directly and apply for 2-3 times in a day.
3. Observe the changes on the skin after a week.
