How does Mendel prove that a trait are independent assortment |
| Answer» Mendel crossed pea plants having round green seeds (RRyy) with pea plants having wrinkled yellow seeds (rrYY).An example of dihybrid crossesSince the F1plants are formed after crossing pea plants having green round seeds and pea plants having yellow wrinkled seeds, F1generation will have both these characters in them. However, as we know that yellow seed colour and round seeds are dominant characters, therefore, the F1plants will have yellow round seeds.Then this F1progeny was self-pollinated and the F2progeny was found to have yellow round seeds, green round seeds, yellow wrinkled seeds, and green wrinkled seeds in the ratio of 9:3:3:1.Independent inheritance of two different traitsIn the above cross, more than two factors are involved, and these are independently inherited. | |

Why does the root of a plant show negative phototropism? |
|
Answer» Shoots show positive phototropism due to accumultion of auxin pn darker side what about roots?how does it take place? The stimuli in phototropism is light. When the plant part grow aginst the direction of stimuli, the tropism is said to be negative phototropism. The roots of the plant grows towards the soil which is opposite to that of light. Here, the plant part is growing against the direction of stimuli. Therefore the roots of the plant show the negative phototropism. No I want the exact reason behind this.. Roots of plant grow in the opposite direction of light.....therefore it shows negative phototropism |

What is the difference between magma & lava |
| Answer» \tMagmaLavaThe molten rock that is present beneath the surface of the earth is termed as Magma.The molten liquid that gets erupted out of the surface of the Earth is termed as Lava. Lava is also referred to as Liquid Magma.The temperature of Magma is slightly hotter and ranges from 1300-2400 degrees Fahrenheit.The temperature of Lava is slightly colder and ranges between 1300-2200 degrees Fahrenheit.The word Magma has its origins from Ancient Greek.The word Lava has its origins from the Italian Language.Lava has the property of cooling much quicker than Magma. This leads to lava sometimes crystalizing into glass.Magma on the other hand takes a much longer time in cooling, as it is located underground which leads to the creation of gigantic crystals.\t | |

Explain in brief on the concept of redox reaction |
|
Answer» Ex CuO+H2=Cu+H2O in this cuo in Lhs but in rhs cu so in this it reduces oxygen this process is called reduction and h2 in Lhs but in rhs is H2O so in this it gain oxygen this process is called oxidation . In this reaction both oxidation and reduction so we can say that it is redox reactions I hope you are understanding my answers In which reaction oxidation and reduction are both present these reactions are called oxidation reduction reactions or redox reactions Those reaction in which oxidation and reduction take place is called redox reaction. Ex- cuo+H2=cu+H2o. the reaction in which oxidation as well as reduction is called redox reaction.....☺☺ |

What information do we get from a chemical equation? Explain with an example |
| Answer» A balanced chemical equation can provide the following information :\tThe reactants and products through their symbols and formulae.\tThe ratio of molecules of reactants and products.\tAs molecular masses are expressed in unified mass (u), the relative masses of reactants and products are known from the equation.\tIf the masses are expressed in grams then the equation also gives the molar ratios of reactants and products.\tIf gases are involved, we can equate their masses to their volumes and calcu-late the volumes or those gases liberated at given condition of temperature and pressure using molar mass and molar volume relationship.\tUsing molar mass and Avagadro’s number we can calculate the number of molecules and atoms of different substances from the equation. | |

Describe asexual reproducation in amoeba |
| Answer» In Amoeba, asexual reproduction occurs by fission (binary7 and multiple). In Amoeba, nucleus first divides into two daughter nuclei by mitosis and then body along with the cytoplasm constricts from the middle, which gradually deepens and eventually divides into two individual parts, each part has one nucleus. Thus, two daughter Amoebae develop from one. This is called binary fission.In multiple fission, nucleus repeatedly divides to form a large number of nuclei, which reach at the periphery. Later cytoplasm gathers around each nucleus to form a daughter Amoeba. In this process, several individuals (equal to number of nuclei) develop from a single Amoeba. | |

What will happen if left side of our heart chambers Is filled with De_Oxynated blood |
| Answer» If the left side of the heart is filled with deoxygenated blood, then the organs will not perfuse which will lead to Multi-Organ System Failure.This can happen with such congenital heart problems such as ASD, VSD, Tetrology of fallot and more often with Transposition of the Greater Arteries. TGA is where the Aorta & Pulmonary Artery have been switched and forces deoxygenated blood to pass through the organs causing death by completely killing all the organs in the body. This can be averted but it\'s almost always deadly.i hope this hlp you | |

What is the function of bile juice?? |
|
Answer» Bile juice is a digestive juice secreted by the liver. Although it does not contain any digestive enzymes, it plays an important role in the digestion of fats. Bile juice has bile salts such as bilirubin and biliverdin. These break down large fat globules into smaller globules in the small intestine so that the pancreatic enzymes can easily act on them. This process is known as emulsification of fats. Bile juice also makes the medium alkaline and activates lipase. Bile juice perform main function it break down the large food globules into smaller ones this function is called emulsification |

What are plant harmone? Name any two. |
| Answer» Auxin is also referred as IAA- indole-3-acetic acid. It was the first phytohormones to be recognized. This plant growth regulator plays an important role in the growth and development of a plant. They play a vital role in:\tAuxin helps in cell enlargement by increasing the plasticity of the cell wall.\tAuxin helps in promoting the growth of the plant’s tissue.\tAuxin is responsible for phototropism and geotropism.\tAuxin helps in promoting root initiation and stem cutting in plants.\tAuxin inhibits the growth of lateral bud by stimulating the production of ethylene.\tAuxin controls the aging and senescence of plants.\tAuxin helps in promoting the growth of many fruits without fertilization.\tAuxin helps in delaying the shedding of leaves.Cytokinins are involved in promoting cell division (cytokinesis) hence it is referred to as Cytokinins. Zeatin is a naturally occurring plant growth hormone, which is isolated from corn plant. Cytokinins are present in all cell division sites including root tips, leaves, fruits, and seeds.\tCytokinins help in stomatal opening.\tCytokinins help in delaying the senescence of leaves.\tCytokinins promote the expansion of cotyledons.\tCytokinins are involved in the enlargement of stem cells.\tCytokinins are also involved in promoting chloroplast maturation. | |

How are fats digested in our body?qhara does this process takes place? |
| Answer» Fats are present in the form of large globules in the small intestine. The small intestine receives the secretions from the liver and the pancreas. The bile salts (from the liver) break down the large fat globules into smaller globules so that the pancreatic enzyme lipase can easily act on them. This is referred to as emulsification of fats. This process takes place in the small intestine. | |
