Which is an example of genetic engineering?
a. humans’ ability to digest cow milk
b. some bacteria’s resistance to antibiotics
c. golden rice enriched with vitamin a
d. lizards with longer legs for surviving floods

The correct answer would be C. golden rice enriched with vitamin A.

Genetic engineering refers to the set of techniques involved in the manipulation of genetic material of an organism.

It includes isolation, modification, and the introduction of the gene of interest in an organism.

It usually aims to modify or introduce characters of interest in an organism.

For example, pest resistant varieties of fruits and vegetables (Bt cotton), increased nutrient contents of a particular food (golden rice), insulin production through bacteria et cetera.

Golden rice is a genetically engineered variety which is produced by introducing three foreign genes required for synthesis and storage of beta-carotene into the plant.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
