Answer:
In medicine, genetic engineering has been used to mass-produce insulin, human growth hormones, follistim (for treating infertility), human albumin, monoclonal antibodies, antihemophilic factors, vaccines, and many other drugs. In research, organisms are genetically engineered to discover the functions of certain genes.

Explanation:
Trace minerals: Trace minerals are defined as the inorganic molecules which are necessary for the human body for the different functions.
Zinc function in human metabolism is defined as a cofactor for numerous enzymes. Zinc play a role as a catalyst in a broad range of reactions. It is involved in the metabolic pathway directly or indirectly with lipids, carbohydrates, proteins, energy metabolism, and they are also important for the cell division process.
They also need for tissue and growth repair, and for reproductive development also. It's also played a vital role in immune system such as wound healing or required for the function and structure of the skin.
Answer:
The theory of plate tectonics states that the Earth's solid outer crust, the lithosphere, is separated into plates that move over the asthenosphere, the molten upper portion of the mantle. Oceanic and continental plates come together, spread apart, and interact at boundaries all over the planet.
