Answer:
Option (A)
Explanation:
In the process of producing electric energy, always a turbine rotates.
The rotation of turbine is due to the falling water in case of hydroelectric power station, due to the heat energy in thermal power station.
As the turbine rotates, the energy of one form is converted into mechanical energy of turbine. Now the generator converts the mechanical energy into electrical energy. It is done by the electromagnetic induction.
When a magnetic flux linked with a coil changes, the induced emf is developed in the coil, this phenomenon is called electromagnetic induction.
Homogeneous - the mixture is even throughout the solution cannot tell one part from another
heterogenous - the mixture is not mixed even and you can tell one compound from another.
NaCl is a homogeneous solution since you cannot visibly separate the NaCl from the water it is dissolved in.

A parasitic relationship is one in which one organism, the parasite, lives off of another organism, the host, harming it and possibly causing death. The parasite lives on or in the body of the host. A few examples of parasites are tapeworms, fleas, andbarnacles.
