Which best describes a similarity between power plants that use water as an energy source and those that use wind as an energy source?

a. both use heat from within earth to produce electricity.
b. both use kinetic energy to produce electricity.
c. both use resources that are not abundant.
d. both use resources that produce a lot of air pollution.

The correct answer to the question is : B) Both use kinetic energy to produce electricity.

EXPLANATION:

Hydroelectricity is produced when the kinetic energy of the falling water rotates the turbine. The generator associated with the turbine is rotated, and electric energy is produced due to electric magnetic induction.

In case of power plants in which wind is used as energy source, the same process happens. The kinetic energy of wind rotates the propellers of wind turbine which in turn produces electric energy.

Hence, the correct similarity between them is statement B.

answer: the correct answer for the fill in the blank is rods.

rods are the specialized photoreceptor cells that are present in the retina of human eye. they are responsible for vision in the night time ( also called scotopic vision). they have very low visual acuity and color distinguishing ability.

as they are responsible for vision in night time, therefore they are found predominantly in the nocturnal animals.
