There are so many examples for that in different areas, like biology experiment carried out in our lab recently.

Answer:
Your carbon atom enters the leaf as CO2 (carbon dioxide) from the atmosphere. In the leaf, chlorophyll uses the energy from the sun to convert CO2 and H2O to the sugar glucose, C6H12O6. Your carbon atom is part of this molecule; it is now one of the carbons in the glucose.
Next, the glucose carrying your carbon atom is sent down the phloem tissue of the carrot plant to the root, which is the carrot itself. Enzymes in the carrot root connect the glucose molecule with your carbon atom into a chain with other glucose molecules, forming cellulose, or plant starch, and there you go. Your carbon atom went from being part of an atmospheric gas to a starch via photosynthesis and starch formation in the root.
Explanation:
A membrane's permeability has an impact on the diffusion rate. As membrane permeability increases, the diffusion rate rises.
- The dispersion of materials is also impacted by changes in temperature and pressure values.
- The passive diffusion rate of penetrated molecules through the biomembrane can be used to quantify a membrane's permeability.
- It is well acknowledged that the permeability of any particular molecule depends mostly on its size, polarity, charge number, and molar mass.
- The capacity for materials to flow into and out of a membrane is known as permeability. The ease with which a chemical can diffuse across a cell membrane determines its permeability.
- Only chemicals that can dissolve in fat can typically pass through a cell membrane.
- The electrical potential gradient across the cell membrane and the concentration gradient of the permeant ion across the membrane together make up the net electrochemical driving force.

Pre-mRNA is the polymer is synthesized during transcription, it is different from polymer being copied in having U instead of A.
A DNA fragment is copied into RNA during transcription. Messenger RNA is the term for DNA segments that are translated into RNA molecules that can encode proteins. Non-coding RNAs are RNA molecules that contain copies of additional DNA segments. Only 1% to 3% of all RNA samples are mRNA.
