What are various life processes. Give extremely |
| Answer» Life processes are the vital processes carried out by living organisms in order to maintain and sustain life. Molecular movements are essential to carry out the various life processes. Thus the processes which together perform the maintenance job are called life processes. Energy required to carry out the different life processes, is obtained through the process of nutrition. A series of chemical reactions in the body are necessary to obtain energy. Oxidising-reducing reactions are some of the most common chemical means to break-down molecules. The process of acquiring oxygen from outside the body, and to use it in the process of break-down of food sources for cellular needs, is called respiration. In the case of a single-celled organism, no specific organs for taking in food, exchange of gases or removal of wastes may be needed because the entire surface of the organism is in contact with the environment. In multi-cellular organisms, various body parts have specialised in the functions they perform.The basic functions performed by living organisms to maintain their life on this earth are called life processes. The basic life processes common to all living organisms are – Nutrition and Respiration; Transport and Excretion; Control and Coordination; Growth; Movement and Reproduction.\xa0 | |

What are the different ways in which glucose is oxidised |
|
Answer» Yes Breaking down of glucose involves two processes. In the first step, it is broken into three carbon molecules called pyruvate. The pyruvate is further broken down into energy in following different ways in various organisms.1) Aerobic respiration : In this case pyruvate is broken down into water and carbon dioxide along with release of energy. It commonly occurs in mitochondria of cells.2) Anaerobic respiration in yeast : In yeast cells during fermentation pyruvate is converted into ethanol and C02 in the absence of 02.3) Anaeorbic respiration in muscles: Due to lack of oxygen, eg. during vigorous running or exercise, in human muscles, pyruvate is converted to lactic acid. |

Give table shows that the various endocrine Grand write their hormone name and function |
| Answer» \tPituitary gland: Enclosed deep within the skull, the pituitary gland is the size of a pea. It hangs on a stalk at the base of the brain. It consists of an anterior portion that produces hormones and a posterior portion that has many neural links. This gland is regarded as the master gland as it controls the functions of all the other glands (such as the adrenal, thyroid glands) in the endocrine system. The pituitary gland stimulates the adrenal gland to secrete cortisol, a steroid hormone controls a range of activities from controlling the body’s metabolism to stimulating blood pressure. The pituitary gland also secretes prolactin, which stimulates the production of milk.\tThyroid gland:The thyroid glands can be found at the front of the neck. It sits low in the throat, between the windpipe. Brownish red, it has blood vessels coursing through it. It secretes hormones that are collectively called thyroid hormones. The most prominent are T3 and T4, which influence the body’s rate of metabolism.\tParathyroid glands: The parathyroid glands consist of four small glands that are located behind the thyroids in the neck. They influence the calcium levels in the body by producing a hormone called Parathyroid Hormone. Sometimes, when the gland produces excess parathyroid hormones, it can have negative effects such as brittle bones and kidney stones.\tAdrenal glands: The adrenal glands sit atop the kidneys and are no larger than a walnut. These glands produce over 150 hormones that regulate different functions in the body. The most well known is Adrenaline, which triggers the flight or fight response. In other words, this is a stress hormone that helps the organism to either face a dangerous situation or to avoid it altogether. | |

Why does light not bend when it enters from one medium to second medium perpendicularly? |
|
Answer» because in plane wave vector is 0 . The phenomenon of change in the path of a beam of light as it passes from one medium to another is called refraction of light.The cause of refraction is the change in the speed of light as it goes from one medium to another.A ray of light travelling in air emerges into water, it will bend towards the normal after entering in to water because as ray of light travels from lighter denser medium to higher denser medium, rays get bend towards the normal due to refraction. |

What is corrosion. How to prevent it |
|
Answer» It is defined as the natural process that causes the transformation of pure metals to undesirable substances when they react with substances like water or air. This reaction causes damage and disintegration of the metal starting from the portion of the metal exposed to the environment and spreading to the entire bulk of the metal.There are various methods to prevent corrosion. These include,1. ElectroplatingIt is the process by which a metal (I) is coated with a thin layer of another metal (II) using electrolysis. In this way, the new metal coating protects the metal (I) from corrosion.2. Cathodic ProtectionIn this process, the base metal is connected to a sacrificial metal that corrodes instead of the base metal. By doing so this sacrificial metal (which is more reactive than the base metal) will give out electrons and get oxidised. The ions thus formed takes part in the corrosion reactions thereby saving the base metal.3. GalvanizationThis process involves coating iron with a thin layer of zinc. It is generally done by dipping iron in molten zinc. The zinc layer coating thus protect the iron inside from corrosion4. Painting and GreasingProviding a layer of paint or grease on the metal can prevent the exposure of the metal with the external environment thereby preventing corrosion.5. Choosing the right material can also help prevent corrosion. Eg: Aluminium and stainless steel are highly corrosion resistant6. Using corrosion Inhibitor Corrosion inhibitors are chemicals which when added to the corrosion environment has the ability to cut down the rate of corrosion. Are u satisfied When any element reacts with moist air it becomes corroded ans process is called corrosion Prevention...PantingAlloying |
