Answer:
1. B
2. C
Explanation:
1. Stem cells have a higher potency than differentiated cells. They are pluripotent and multipotent cells that can differentiate into most types of cells. Therefore they can be used to repair injuries that take long to heal naturally. An example is applying stem cells on joints of people with arthritis to enable cartilage of knee caps regenerate.
2. Bionics is a form of engineering that mimics human physiology but is not made of tissues but rather mechanicals made of a material like titanium. An amputee, for example, will have a mechanical arm or leg on the amputated limb that functions like a real limb. Usually, in the best form of bionics, the subject is able to control the artificial limb with their mind.
