How do mendal experiment show that traits maybe resisive or dominant |
|
Answer» It follows law of dominance. When mendel crossed two plants for a single character that is the height of plant... U need to show monohybrid cross also in ur answer. (a) Mendel demonstrated that traits can be either dominant or recessive through his monohybrid cross. He crossed true-breeding tall (TT) and dwarf (tt) pea plants. ... They appeared tall only because the tall trait was dominant over the dwarf trait. This shows that traits may be dominant or recessive. |

why sky appears blue not violet? |
|
Answer» Because before the light reaches to the surface of earth, some amount of light like Violet colour light is absorbed by the earth\'s atmosphere..particles present in the atmosphere scatter the shorter wavelength colours like blue. So sky appears to be blue not violet. When light from the sun enters Earth\'s atmosphere, it is scattered, or deflected, by molecules in the atmosphere — primarily nitrogen and oxygen. Shorter wavelengths (blue and violet) are scattered more than longer wavelengths (red and yellow) Because violet colour are scratted out. |

What is mean by double fertilisation |
|
Answer» It is a complex fertilisation which occur in plants in which a female gamaet joins with two male gamaets. It occurs when one male nucleus fertilizes (fuses) with egg cell to form zygote cell and other male nucleus fuses (fertilizes) with two polar nuclei to cause triple fusion. |

Why hcl is present in stomach not the another acid |
|
Answer» Hcl is present in stomach for two reasons 1- to activate Pepsin from pepsinogen.2- to act as a wall to protect the stomach fr9m being dissolved by Pepsin Hydrochloric acid plays an important role in food digestion. The acid is made by parietal cells in the stomach lining and does its job in the stomach cavity, or lumen. ... Other stomach lining cells known as chief cells make a substance called pepsinogen. Hydrochloric acid converts pepsinogen into an enzyme called pepsin. Thank you?? Because it helps to neutralise the base which is present in stomach |

What is snells law with mathematically formula |
|
Answer» Snell’s Law –\xa0The Laws of RefractionThe point of refraction is created where the incident ray lands and the angle that it makes with the refracted ray not forgetting the normal line that is dropped on the plane perpendicularly. The medium through which the rays of light are passing creates a considerable difference in refraction unlike in reflection. The refractive indices make the dependency on the medium apparent in Snell’s Law.The following is a diagrammatic representation:The normal on the surface is used to gauge the angles that the refracted ray creates at the contact point. n1and n2are the two different mediums that will impact the refraction. Snell\'s law is defined as “The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant, for the light of a given colour and for the given pair of media”. Snell\'s law formula is expressed as: ... n1 and n2 are the two different mediums that will impact the refraction. |
|
| 66966. |
What is absolute index |
|
Answer» a number indicating the speed of light in a given medium as either the ratio of the speed of light in a vacuum to that in the given medium (absolute index of refraction) or the ratio of the speed of light in a specified medium to that in the given medium (relative index of refraction) . Symbol : n. The absolute refractive index of any medium is the refractive index of the medium with respect to vacuum. It is always greater than 1. |

Why we have 2 eyes? |
|
Answer» We have two eyes to focus property on any object.And to see wide range of angle 180° Because two eyes gives us wider field of view We need two eyes because a human being has a horizontal field of view of about 150° with one eye and of about 180° with two eyes. Thus, two eyes provide us wider horizontal field of view.With one eye, the world looks flat, i.e., two dimensional only. With two eyes, the view is three dimensional, i.e., dimension of depth is added to our view......Now, happy??keep smiling........ |

How we find groups and periods in chemistry |
|
Answer» If electrons have 3 valency then 10+3=13 Groups means vertical.... Periods mean horizontal DirectionsIn groups-------->In periods direction towards down Vartical columns called "groups\'\' and horizontal rows called " Period\'\'. Number of shells is equal to the number of periods and electrons in the last shell gives us the group number. If the electron in last shell is less than 3 then it\'s group number is same but if it is more than 3 then v have to add 10 to it to get group number |

ozone ia havier than oxygen then also why it is above oxygen |
|
Answer» Bcoz oxygen = O\'2 and ozone =O\'3 Its highest concentration is found in the ozone layer of the atmosphere, which absorbs most of the harmful ultraviolet rays emitted by the sun. ... As such, ozone should weigh more than oxygen and should therefore be closer to the ground. However, as you may know, it\'s not like that. |

How we prepared soft water to hard water |
| Answer» Hardness in water is a primary concern for industries, households and municipal water systems. The hardness in water when present in quantities above the desired level cause problems like scaling, decreased action of detergents and frequent corrosion. Besides these problems, normally the hardness in water is not harmful when found in acceptable range for both domestic and industrial uses. Brewing industry requires moderate to extremely hard water for better brewing. Hard water minerals like calcium and magnesium are required by the human body for smooth metabolic functions. Making hard water is not very difficult, it requires simple equipments and a few chemicals.Wear protective glasses and rubber gloves. Pour 500 milliliters of distilled water into a calibrated beaker, water level touching the 500 milliliters mark in the beaker.Add half tablespoon of epsom salt to the distilled water. Stir well to completely dissolve the salt and make a clear solution. Calcium chloride increases the permanent hardness of water.SCIENCING VIDEO VAULTAdd half tablespoon of baking soda to the solution. Stir the solution well to completely dissolve the baking soda. Baking soda generally increases the temporary hardness of water.Add half table spoon calcium chloride to the solution and stir to completely dissolve calcium chloride in the solution. Calcium chloride increases the permanent hardness of water.Leave the solution for few hours. Generally 2 hours of time will be enough for complete dissolution of the minerals into the solution.Make a filter cone with the filter paper. Filter the solution slowly with a the filter cone into another beaker to remove any suspended material.TipThe hardness of water is directly proportional to the amount of magnesium salt and bicarbonate present in it. Adding more salt will result in higher hardness up to a level.WarningDo not expose your bare skin to the chemicals.

What is pressbiopia.? |
|
Answer» Presbyopia is a defect of eye which is caused due to old age of a person in which far objects as well as near by objects r not visible. Main reason behind this defect is the weakening of ciliary muscles. This defect can be corrected by using bifocal lens which have concave lens on upper side and convex lens on lower side. Presbiyopia is the old age hypermetropia in which the person is unable to see the far and near objects both. It is caused due to the weakening of ciliary muscles in old age. It is corrected by using a bifocal lens containg both concave and convex lens. It is a kind of eye disease in which people is unable to see the both far and near distance object. |

How many chambers in human Heart and its function |
|
Answer» 4 The heart has 4 chambered . Two atria and two ventricle s. The right atrium receive oxygen poor blood from the body and pump it to righr ventricle. The right ventricle pump the oxygen poor blood to the lungs the left atrium receive oxygen rich blood from the lungs and pumps it to the left ventricle. Human heart has 4 chambers1.left atrium2.right atrium3.left ventrical4.right ventrical.Functions......1.... the oxygenated blood from lungs enters the left atrium from here it goes to left ventrical and from here the blood enters our body through aorta.2.... now through vena cava the deoxygenated blood from body enters the right atrium from here it goes to right ventrical and from here it goes to lungs.As blood enters the heart two times once from left and once from right therefore its known as double circulation. 4 Four chamber 4 4 chambers |
