What is earth wire ..? How it works in our domestic circuit |
|
Answer» The earth wire gives a safe route for the current if the live wire touches the outer casing. Livewire is A wire carrying electric current. The metallic body is connected to the earth wire, which provides a low resistance-conducting path for the current. It ensures that any leakage of current of the metallic body the appliance will flow to the earth only and the user may not get a severe shock. we connect the\xa0earth wire\xa0to metal casing of electrical appliances by using three pin plug. If by chance, live\xa0wiretouches any metal case parts of appliances then current passes directly to\xa0earth. hence\xa0earthing\xa0is used as safety measure to prevent shock from metal objects. |

Veins are thin walled and have valves. Justify |
|
Answer» Veins are thin walledbecause the veins collect blood from different body organs to the heart and they have valves to ensure that blood flows only in one direction Veins collect the blood from different organs and bring it back to the heart. The blood is no longer under pressure so, the walls are thin with valves to ensure that blood flows only in one direction. Veins are thin-walled and have valves that prevent the blood from flowing back in the wrong direction.Veins carry blood heading towards the heart.Blood comming from the tissue has delivered O2 and picked up CO2 from the cell.

Brief explanation about respiration |
| Answer» Respiration is the oxidation of respiratory substrates (mainly glucose) in the cells resulting in the release of carbon dioxide and energy. It involves release of energy in the form of ATP. The initial steps of glucose break down occurs in the cytoplasm and results in production of pyruvic acid. This process is called glycolysis or E. M. P. Pathway. One molecule of glucose breaks down to produce two molecules of pyruvic acid. Each pyruvic acid molecule has three carbon atoms. This pathway doesn\'t require oxygen.Aerobic respiration occurs in the presence of O2 where O2 is utilised. Glucose is completely broken down to release end products in the form of CO2 and water. It takes place in cytoplasm and mitochondria.Anaerobic respiration occurs in the cytoplasm in the absence of O2. Glucose is incompletely oxidised to release the end products in the form of ethyl alcohol and water (in plant cells and yeast) and lactic acid (in animal cells). | |

Why does an acques solution of acid able to conduct electricity? |
|
Answer» Due to present of charged particle is called ions Because it contains ions . The aqueous solution of acid contain H+ ions and free ions/electrons are responsible for conducting electricity.And in aqueous state ions can moves freely to conduct electricity Acids\xa0undergo dissociation in\xa0aqueous solution\xa0to form H+ ions. When\xa0electricity is\xa0passed through an\xa0aqueous solution\xa0of an\xa0acid, the H+ ions reach the cathode and each H+ ion picks up one electron from the cathode to form H2 gas. Because of this reaction, an\xa0aqueous solution of acid conducts electricity. The aqueous solution of acid conduct electricity because the acid solution have H+ ions and the movement of these ions helps for the flow of electrical current through the solution. |
