Answer:
The prime advantage of using electromagnets in a device is that it can be easily turned on and off.
Explanation:
The formation of electromagnets is done by winding a wire via a magnetic substance and then passing an electric current through it. The durability of the electromagnet relies upon the size of the electric current via the coil and the number of coils.
On the other hand, the regular magnets do not need power, however, it is reliant upon the kind of material that is, used to produce it. Thus, it is advantageous to utilize electromagnets in comparison to permanent magnets as the strength of the electromagnet can be amended easily by monitoring the concentration of current flowing through it. Thus, it is easy to turn off and on any device containing an electromagnet.
Electromagnets can be switched on and off. This is good in a scrap yard because they need to pick heavy pieces of metal and then drop it.
A conductor allows heat to flow easily, while an insulator resists heat flow. In general, metals are good conductors of heat and electricity.
A substance or material that permits the flow of electricity is known as an electrical conductor. When voltage is provided, electrical charge carriers, often electrons or ions, travel effortlessly from atom to atom in a conductor.
There are four different kinds of conductors: semiconductors, resistors, excellent conductors, and non-conductors.
Aluminum, gold, copper, brass, steel, and steel are all effective conductors of electricity. In the form of wires, we employ them in electrical circuits and systems. A great liquid conductor is a mercury. As a result, this material is used in numerous instruments. Thus, metals are good conductors.

Answer:
Copper Lead and Glass
Correct answer: Photosynthetic autotrophs are organisms that use light energy and carbon dioxide to make sugar and oxygen
Plants are known to be the photosynthetic autotrophs that are capable of making their own food by the process of photosynthesis in the presence of sunlight. It occurs mainly in the green pigment found in the leaves of the plant called chlorophyll.
Example: Green algae, green plants, and photosynthetic bacteria.
b. to lay their eggs
c. to have water for drinking only
d. to be close to flora for protection
