Electric Current Is The Flow Of ________ Through A Substance.

Answers

Answer 1

Answer:

Electrons

Explanation:

Answer 2

Answer:

A current is a flow of electrons for this to happen there must be a closed circuit.

- The electricity is nothing but a flow of free electrons present in the external surface of the electricity conducting substance.

The flow direction of this electron flow is also the direction of electricity flow.

- There is a type of electrical circuit which is known as the closed circuit. This circuit is completely connected with the two terminals of the battery and there are no hindrances in the path of electricity flow in these circuits. That's why current can only flow through these complete circuits.

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.

Answers

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.

A mammal's red blood cells produce the protein hemoglobin, which carries oxygen through the bloodstream. Its hair follicle cells do not produce hemoglobin. Which statement is true about these differences? A) The red blood cells contain different genes than the hair follicle cells, causing the cells to differentiate B) The red blood cells contain DNA, but the hair follicle cells do not C) A red blood cell and hair follicle cell have the same genes, but they are expressed differently D) The hemoglobin is produced from recombinant DNA, which is only found in red blood cells

Answers

Answer:

C) A red blood cell and hair follicle cell have the same genes, but they are expressed differently

Explanation:

All cells of a living organism contain the same genetic sequence i.e. they contain the same set of genes, however, differences in the expression of these genes may occur. This is responsible for the different specific roles or functions played by organs of the body system.

The expression of a gene refers to the process by which a gene is transcribed and translated into a protein molecule, which is responsible for traits in the body. Genes are expressed differently in order for certain cells to function differently and specifically. For example, difference in expression of genes is responsible for the ability of red blood cells to produce hemoglobin and the inability of hair follicle cells to, even if they contain same genes.
