Item 5 What is the role of a generator in producing electricity? The generator stores electrical energy for later use in homes and businesses. The generator spins the turbine to create mechanical energy. The generator transforms the mechanical energy of the turbine into electrical energy. The generator reverses the turbine to create electrical energy.
Answer:
The generator transforms the mechanical energy of the turbine into electrical energy
Explanation:
Electricity generator is a device that is used in generating power supply which can be used in industries, homes and for commercial and private purposes.
It operates by converting mechanical energy into electrical energy for the use in an external circuit. mechanical energy can be obtained from steam turbines, internal combusting energy, gas and water turbines and it can be obtained through the rotating shaft.
The capacity of each generator determines the amount of energy it can supply to a given place.

of stamens would be able to produce
Explanation:
No C is the answer
Reproductive structures are structures that make up the reproductive organs of a particular organism. These structures could include either female or the male reproductive organs.
Flowers with reproductive structures that comprise of only stamen would produce only pollen (option c).
Stamens are reproductive organs found in plants and they are male reproductive organs. For fruits with seeds to be formed the male and female reproductive organs must come together to produce a fruit.
Flowers with only the stamen will produce only pollen which is a male gamete that needs to be joined to the female gamete, ovary produced from the female reproductive structure (pistil) in a plant to produce a fruit.
