Further explanation:

Chemistry:

Chemistry is the discipline of science which deals with the study of matter, its composition, structure and its properties. There are many branches of chemistry such as organic chemistry, inorganic chemistry, analytical chemistry and environmental chemistry.  

Bioplastic:

Bioplastic is an alternative of the traditional plastic. It is generated from the sustainable sources, for example vegetable oil. It is a biotechnology product. It is degradable up to hundred percent.

Bioplastic advantages:  

  1. It saves energy during its production.  
  2. It consumes only renewable resources and does not consume non renewable resources.  
  3. Reduction of the environment polluting non-biodegradable wastes.  
  4. It contains no heath damaging additive.
  5. It does not change the taste and the smell of the food that is stored in it.  

A mechanical implant that delivers:

Implant:  

Implant means surgically implanting of anything in the body. It is different from transplant.  

A mechanical implant that delivers is a device that is manufactured by human beings, which performs the function of a missing biological structure. It delivers the medicine inside the human body. So, it is considered as the example of biotechnology.
