Answer:
If damage is done to the human skeletal structure it cannot be healed or reversed: INCORRECT.
Step-by-step explanation:
- Human DNA is capable of repairing itself: CORRECT. It has several ways to do it, repairing bases through excision, by photoreactivation, repairing mismatches, by repairing double-strand breaks and activating SOS responses.
- If damage is done to the human skeletal structure it cannot be healed or reversed: INCORRECT. The human body has a bone healing process that allows the creation of a cartilaginous scaffold than then becomes a bone matrix transforming the outer laminar bone into compact bone.
- The human skin is capable of self-heal due to the human cells: CORRECT. A wound in human skin is healed in a process that includes hemostasis, the creation of a blood clot, followed by an inflammatory phase and de successive creation of new epidermis. Many human cells are involucrated, such as fibroblasts and macrophages.
- When synthetic material gets damaged it's irreversible: CORRECT. These kinds of materials do not have a system to self-heal by itself.
- Biological material has the capability of healing due to vascularity and its cells: CORRECT. Vascularization is the growth of blood vessels, it is fundamental to have effective transport of oxygen, nutrients, and removal of cell-secreted waste for the survival of cells, this allows the biological material to heal.
