Please anyone tell me about refractive index . Explain about it |
|
Answer» Refractive index is the extent of bending of ray of light by the medium. It does not have any SI unit as when we we will define it in realtion to speed we will get the no units because i.e.,in relation to speed Refractive index. =speed of light in medium 1/speed of light in medium 2We knew SI unit of speed is m per second so it will cancell out we will not get any unit .thus, it does not have unit. The symbol of refractive index is nu(n) its not \'n\' alphabet ,the first line of n alphabet is little bit smaller then second line of n alphabet. Factors on which refractive index depend--1. Nature --whether the object is transparent or not it is not then no bending of light take place as there is not refraction taking place. 2. Wavelength -- Refractive index is inversionaly proportional to wave length, more will be the wavelength less will be the refractive index and vice versa. 3.colour -- red light has highest wavelength so it shows less bending due less refractive index and more wavelength.Violet colour of light shows maximum bending due to less wavelength. Refractive index of air and vaccum is same - 1.00Diamond had the refractive index of- 2.42 The ratio of the velocity of light in vaccum with the ratio of velocity of light in specified medium is known as refractive index. Refractive Index\tThe extent of the change in direction that takes place in a given pair of media is expressed in terms of the refractive index.\tIt turns out that light propagates with different speeds in different media.\tThe value of the refractive index for a given pair of media depends upon the speed of light in the two media.\tn21 = Speed of light in medium 1 /Speed of light in medium 2 = v1/v2 |

Why are traits acquired during the lifetime of an invidual not inherited? |
| Answer» Traits are inherited during a lifetime cannot be inherited in the successive generation as the changes do not reflect in the DNA of the germ cells. For example, a cricket player cannot pass on his skills on to his next generation as the traits acquired during his lifetime are limited only to non-reproductive cells. However, any mutations in the germ cells can result in the new traits being acquired by the successive generation. | |

Why mucus is present in the stomach |
|
Answer» To protect the stomach wall from acid Stomach mucus protects the gastrointestinal cells from the damage that gastric juices can cause. Gastric juices are highly acidic and, without this mucus, the acid can destroy the cells and tissues in the stomach.Mucus in the stomach is rich in bicarbonate, an alkaline compound, to help lubricate and protect the stomach. Stomach acid comes from the parietal cells, a type of stomach cell, and it is a hydrochloric acid, which is a solution of water and hydrogen chloride. This allows the environment in the stomach to be highly acidic. A high level of acidity is critical to inactivate bacteria in the food that people eat and to activate pepsinogen, a type of enzyme. |

Ohm\'s law maens what |
|
Answer» Ohms law define that the potential difference between the two point of a mettaloc wire Potential difference and eletric current are directly proportional to Resistance Ohm’s Law states that the potential difference between two points is directly proportional to the electric current.This means; potential difference V varies as electric current.Or,\xa0V∝IV∝IOr,\xa0VI=RVI=R-----------(1)Or,\xa01I=RV1I=RVOr,\xa0I=VRI=VR----------(2)Or,\xa0V=RIV=RI\xa0----------(3)Where R is constant for the given conductor at a given temperature and called resistance. Resistance is the property of conductor which resists the flow of electric current through it. OHM’s LawOHM’s law states that under no same temperature,\xa0electric current\xa0flowing through an ideal conductor is\xa0directly proportional to the potential difference\xa0across its ends.V ∝ IV = IR, R – Resistance\tResistance\xa0is a property of conductor to resist flow of charge through it. Its SI unit is\xa0Ohm (Ω).R = V/I, 1 Ohm = 1 Volt/ 1 Ampere\tI = V/R denotes that\xa0Current is inversely proportional to Resistance. Hence, greater the resistance lesser will be the flow of current and vice-versa.\tA\xa0rheostat\xa0or a\xa0variable resistor\xa0is a device or a component which allows changing of resistance in a circuit keeping the voltage same.\tIn a conductor, electrons are attracted by the atoms. This is a resistive force which is lower for a good conductor but very high for an insulator. A conductor having some resistance is called a\xa0Resistor. |

how mensuration cycle take place in women |
| Answer» Since the ovary of female release one egg every month, therefore, the uterus also prepares every month to receive a fertilised egg. The inner lining of the uterus becomes soft and thick with lots of blood capillaries in it. This preparation is necessary as in case the egg is fertilised by the sperm, it helps to keep the egg and nourish it. If however, the egg is not fertilised, then the thick lining of the uterus is not required and the uterus lining breaks down and comes out through the ****** in the form of blood and mucous. This is called menstruation.(b) Menstruation cycle in females:(i) When a girl reaches puberty at the age of 10 – 12 years, the *** hormones released it her blood cause some of the ova in the ovaries to become mature.(ii) Usually one mature egg is released from the ovary into the oviduct once every 28 days. This is called ovulation.(iii) Before ovulation, the inner lining of the uterus becomes thick and spongy, and full of blood capillaries, and prepares itself to receive the fertilised egg.(iv) If the ovum does not get fertilised, then the thick and soft inner lining of the uterus is no longer needed and hence it breaks and the dead ovum comes out from ****** in the form of bleeding called menstruation.(v) Menstruation usually occurs 14 days after ovulation and usually lasts for 3 to 5 days.(vi) After menstruation is over, the inner lining of the uterus starts building up again so that it becomes ready to receive the next ovum in case it gets fertilised.(vii) If the ovum does not get fertilised even now, then the menstruation takes place again and this cycle goes on repeating. | |

Define alvoeli |
|
Answer» Within the lungs, the passage divides into smaller and smaller tubes which finally terminate in balloon-like structures which are called alveoli. The alveoli provide a surface where the exchange of gases can take place. The walls of the alveoli contain an extensive network of blood-vessels. When we breathe in, the ribs are lift up and the diaphragm flattens which increases the size of the chest cavity. Because of this, air is sucked into the lungs and fills the expanded alveoli. The blood brings carbon dioxide from the rest of the body for release into the alveoli, and the oxygen in the alveolar air is taken up by blood in the alveolar blood vessels to be transported to all the cells in the body. During the breathing cycle, when air is taken in and let out, the lungs always contain a residual volume of air so that there is sufficient time for oxygen to be absorbed and for the carbon dioxide to be released. (i) The\xa0alveoli\xa0are thin walled and richly supplied with a network of blood capillaries to facilitate the exchange of gases between blood and the air filled in\xa0alveoli.(ii)\xa0Alveoli\xa0have balloon - like structures with thin elastic walls. These provide maximum surface for exchange gases. |

Full detailed information or notes on "excretion"? |
|
Answer» Which system is good, double coincidence of want or ? money??? EXCRETION\tThe biological process of removal of harmful nitrogenous metabolic waste from the body is called excretion.\tUnicellular organisms excrete by diffusion and multicellular organisms use specialized organ to perform same function.Excretion in human beings\tA pair of kidneys, a pair of ureters, a urinary bladder and a urethra constitutes the human excretory system.\tKidneys are present on either side of the backbone in the abdomen.\tKidneys produce urine and urine from kidney passes through the ureters into the urinary bladder and remains stored their until it is released through the urethra.\tUrine is produced to filter out waste products from the blood.\tNephrons are basic structural and functional unit of kidney.\tCluster of thin walled blood capillaries called\xa0glomerulus\xa0in the nephron filtrate the urine and each cluster is associated with cup shaped end of a tube called\xa0Bowman’s capsule.\tSubstances like glucose, amino acids, salts and a major amount of water is selectively reabsorbed from the initial filtrate as the urine flows along the tube.\tReabsorption depends on the amount of excess water in the body and dissolved waste to be excreted.\tThe urine from kidney enters the long tube called ureter.\tUreter connects the kidney with the urinary bladder and urine from the kidney is passed to urinary bladder and stored in the bladder.\tWhen the pressure in the expanded bladder leads to the urge to urinate, the urine is passed out through urethra. |

Grafting means |
|
Answer» Hey it have a very simple definition ?...that .......It is a type of artificial reproduction only for plants ..in which the stem which have roots called is inserted in soil and upper part called Scion they both r attached with a tape and later u will get a new variety of fruits ?But don\'t take stock of mango ? and Scion of lemon?....Thank you ? \xa0Grafting:Grafting\xa0is a\xa0horticultural technique used to join parts from two or more plants so that they appear to grow as a single plant. In grafting, the upper part (scion) of one plant grows on the root system (rootstock) of another plant.In grafting, one plant is selected for its roots, and this is called the stock or rootstock. The other plant is selected for its stems, leaves, flowers, or fruits and is called the scion. The scion contains the desired genes to be duplicated in future production by the stock/scion plant. For successful grafting to take place, the vascular cambium tissues of the stock and scion plants must be placed in contact with each other. Both tissues must be kept alive until the graft has taken, usually a period of a few weeks. Successful grafting requires that a vascular connection takes place between the two tissues. Grafting is most commonly used for the propagation of trees and shrubs grown commercially. Grafting is limited to dicots and gymnosperms. |

Why DNA copying necessary |
|
Answer» Simple points1. Transfer the genes 2.responsible for heredity 3.it induces variation 4. Beneficial for species5. Evolution occurs 6.tells about the relations..Only to understand Thank you ? \xa0The copying of DNA during reproduction is important because:\tThe replication of DNA ensures that each daughter cell formed at the end of cell division, receives equal amount of DNA.\tIf DNA won\'t be copied then the daughter cells won\'t receive all necessary genes.\tThere may be absence of important proteins which are encoded by DNA, if DNA won\'t be replicated.\tCopying of DNA may result in recombination which will lead to evolution.\tTransfer of genetic material from one generation to other makes the organisms to have similar functions.\tStability of population is maintained. |

what is asaxual reproduction |
|
Answer» Asexual reproduction is a mode of reproduction in which a new offspring is produced by a single parent. The new individuals produced are genetically and physically identical to each other, i.e., they are the clones of their parent.Asexual reproduction is observed in both multicellular and unicellular organisms. This process does not involve any kind of gamete fusion and there won’t be any change in the number of chromosomes either. It will inherit the same genes as the parent, except for some cases where there is a chance of rare mutation to occur. No gametic fusion The process of reproduction in which only a single parent is involved is known as asexual reproduction |
