Explain Why A Complete Circuit Is Necessary For A Nonzero Current To Exist

Explain why a complete circuit is necessary for a nonzero current to exist   First let us define what current is. CURRENT is the rate of flow of charge. It is, on a more specific definition, the CHARGE PER UNIT TIME or Current = charge / time I = Q / t which is expressed in the unit of Ampere (A) named after the French Physicist and Mathematician André-Marie Ampère. Where can we typically find an electric current? In on our homes, we can find it on a COMPLETE CIRCUIT which consists of a source, a load, and a wire (sometimes also include a switch for more specific one). When all the parts of a complete circuit are connected among each other, the current flows from the source, through the wires, and then to the load which consumes the energy and then back to the source. If one among the parts are lost or are removed, then the circuit is not complete or simply not closed. If the circuit is not complete, then the current cannot flow anywhere. Why is this so? That is, current can only

How Do Organisms Differ From One Another

How do organisms differ from one another   Organisms differ from one another because of the differences in their DNA. The DNA is so called the "blueprint of life" because its function is to code for all the information that is needed by your body to create you. The differences in the DNA among organisms is called genetic diversity . For organisms of the same species, recall that in meiosis, the homologous chromosomes of living cells have an event called synapsis or crossing over . This crossing over of genetic material in homologous chromosomes ensures that each daughter cell that will be produced by meiosis will have no identical pair. This is important to increase the survival of the future generation and to reduce chances of acquiring genetic diseases. This is also the reason why no two organisms are the same, even if they came from the same parents, even identical twins have a very small difference in their DNA. Evolution takes place for organisms of different spe
