Red platelets are too vast to leave any capillaries. As capillaries are just a single cell thick and have thin porous dividers this implies substances can diffuse out of them effortlessly. Helpful substances, for example, oxygen and sustenance diffuse out of the blood in the vessels into the tissue liquid where it is then taken to the cells.
Feedback occurs when outputs of a system are routed back as inputs as part of a chain of cause-and-effect that forms a circuit or loop. The system can then be said to feed back into itself

Explanation:
A DNA molecule is a double-stranded molecule made up of nucleotide units. According to this question, radiation can damage the nucleotides in the DNA molecule. However, the cell can repair this DNA molecule by removing the single damaged nucleotide and replacing it with an undamaged one.
In this case, the cytosine nucleotide is the damaged nucleotide. To repair this DNA in the image, the covalent bond holding the one nucleotide to another in one of the DNA strands must be broken.
The sugar-phosphate bonds as represented by letters Y and Z are the bonds that could be broken to replace the cytosine nucleotide by an undamaged one, without affecting the biological information coded to the DNA molecule. The bonds holding the neighboring nucleotides are also broken during the repair process. Note that, this form of repair is called BASE EXCISION REPAIR
