Define double fertilisation ? |
| Answer» Double fertilization is a complex process which involves the fusion of one female gametophyte with two male gametes.Double fertilization is a major characteristic of flowering plants. In this process, two male gametes fuse with one female gamete wherein one male gamete fertilizes the egg to form a zygote, whereas the other fuses with two polar nuclei to form an endosperm.Double fertilization gives stimulus to the plant that results in the development of the ovary into fruit and ovules into seed. The fusion of haploid male and female gametes restores the diploid condition of the plant. | |

What are various evidences in favour of evolution? |
|
Answer» Fossils of early man, dinosaurs are the various evidences in favour of evolution. The following are the various evidences in favour of evolution:\tHomologous organs: Organs with a common basic structural design but with different functions are said to be homologous organ. For example, forelimbs of a frog, lizard, bird and man.\tThe forelimbs of man are used for grasping, of lizard for running, of frog for propping up and bird for flying. They have different functions but have same structural pattern.\tAnalogous organs: The analogous organs have different basic structure but perform similar functions. For example, the wing of insects and the wing of birds, have a totally different anatomy and origin but they perform the same function of flying in air.\tEvidences from fossils: The fossils also provide evidences for evolution. For example, the fossil Archaeopteryx looks like a bird but it bears a number of other features, which are found in reptiles. This observation provides a clue that birds have evolved from reptiles. |

Give an example of redox reaction and name the reducing agent and oxidizing agent |
| Answer» H2S + Cl2\xa0→ 2HCl + SThe O.N. of S increases from -2 to 0. So it is undergoing oxidation and O.N. of Cl2\xa0decreases from 0 to -1. So it is undergoing reduction. Therefore it is a redox reaction.CuO + H2\xa0→ Cu +H2OIn this redox reaction, CuO is getting reduced to Cu since Oxygen is getting removed. So, the conversion of CuO to Cu is reduction reaction. H2\xa0is getting oxidised to H2O. So, it is oxidation reaction.Fe(s) + CuSO4(aq) → FeSO4(aq) + Cu(s)Oxidation state of Fe changes from 0 to +2 and oxidation state of Cu changes from +2 to 0 | |

male reproductive system explaination |
| Answer» The human male reproductive system consists of: \tTestes - Are the primary reproductive organs in males which are in pair. These are oval shaped organs which lie outside the abdominal cavity. It makes the male *** cells called sperms and produces male *** hormones called testosterone. The testes are situated in the scrotal sac outside the main body cavity because the formation of sperms requires a lower temperature than the normal body temperature.\t******* - Is a muscular pouch which houses the testes. It is present outside the abdominal cavity and maintains a lower temperature than the normal body temperature.\tEpididymis - The sperms formed in the testes goes into a coiled tube called epididymis which stores the sperms temporarily.\tVas Deferens (sperm duct) - It is a long tube which carries the sperms from epididymis to another tube called urethra.\tSeminal vesicles and prostrate gland - Both these glands are present along the path of vas deferens and add their secretions to sperms which allows them to transport easily.\t***** - It is an organ which passés the sperms from the man\'s body into the ****** in the women\'s body during mating. | |

Mandleev |
| Answer» \tMendeleev’s Periodic Table:\tMendeleev believed that the atomic mass of an element was the most fundamental property in classifying elements.\tMendeleev arranged elements in the increasing order of their atomic masses and observed that the elements showed repetition after certain intervals in their physical and chemical properties.\tHe arranged the known elements in the increasing order of their atomic masses in horizontal rows, till he encountered an element which had properties similar to the first element.\tMendeleev placed the element below the first element and started the second row of elements.\tProceeding in this way, he created the first periodic table containing 63 elements, arranged according to their properties.Mendeleev’s Periodic Law: The physical and chemical properties of elements are a periodic function of their atomic masses.\xa0Features of Mendeleev’s Periodic Table:\tThere are seven horizontal rows in the periodic table, numbered from 1 to 7. These seven rows are called periods.\tThere are eight vertical columns numbered from I to VIII. These eight columns are called groups. Groups I to VII are further divided into sub groups A and B.\tThe properties of elements in a particular period show regular gradation from left to right. | |

Define area of cross section |
| Answer» Most wire is made with a circular cross section of some particular radius and diameter. The area of that cross section is the well known A = pi*R² which is colloquially pronounced as “pie are squared.” We will put aside the old joke that “Pie are not squared; pie are round” but we have to admit to ourselves that expressing area and having to work with the irrational number “pi” can get numerically awkward. | |

Write the cleansing action of soaps and detergents? |
| Answer» Soap and detergents help insoluble particles to become soluble in water. It makes the cleaning easy. Oil or fats are insoluble in water. Soap molecules has two parts- the polar head and the long hydrocarbon tail. The insoluble oil/fat molecules become associated inside the micelle formed by soap molecules with polar hydrophilic (water-loving) groups on the outside and encasing a hydrophobic (water-hating) pocket, which shields the oil/fat molecules from the water making it soluble. Once the dirt or fat molecules are dissolved in water, it can be rinsed away easily. | |

How urin is formed |
|
Answer» Urine formation is carried out by the excretory system. The nephrons play a major role in this. They carry out urine formation in various steps like glomerular filtration, selective reabsorption and tubular secretion.1.\xa0Each nephron has a\xa0glomerulus, the site of blood filtration. The glomerulus is a network of capillaries surrounded by a cuplike structure, the glomerular capsule (or Bowman’s capsule). As blood flows through the glomerulus, blood pressure pushes water and solutes from the capillaries into the capsule through a filtration membrane. This glomerular filtration begins the urine formation process.2.\xa0Inside the glomerulus, blood pressure pushes fluid from capillaries into the glomerular capsule through a specialized layer of cells. This layer, the\xa0filtration membrane, allows water and small solutes to pass but blocks blood cells and large proteins. Those components remain in the bloodstream. The filtrate flows from the glomerular capsule further into the nephron.3.\xa0The resulting filtrate contains waste, but also other substances the body needs: essential ions, glucose, amino acids, and smaller proteins. When the filtrate exits the glomerulus, it flows into a duct in the nephron called the\xa0renal tubule4. Waste ions and hydrogen ions pass from the capillaries into the renal tubule. This process is called\xa0secretion. The secreted ions combine with the remaining filtrate and become urine. The urine flows out of the nephron tubule into a collecting duct. It passes out of the kidney and down to the bladder.Urine\xa0is a liquid or water waste product that passes through your\xa0urinarytract and is expelled from your body through your urethra. It contains 90-95% water. If you talking about lab condutions then it us likley to be(Na)2SO4+KCNO = NH4CNO+k2SO4 1 filtration .2 reabosortion |

What is anti matter and dark matter |
|
Answer» Antimatter is just regular matter with a few properties flipped, such as the electric charge. For example, the antimatter version of an electron is a positron. Antimatter is very rare in our universe compared to regular matter, but there are small amounts of antimatter all over the place in the natural world, including inside your body. Antimatter is created by many types of radioactive decay, such as by the decay of potassium-40.Dark matter is matter that does not interact electromagnetically, and therefore cannot be seen using light. At the same time, dark matter does interact gravitationally and can therefore be "seen" through its gravitational effect on other matter. It is common throughout the universe and helps shape galaxies. In fact, recent estimates put dark matter as five times more common than regular matter in our universe. But because dark matter does not interact electromagnetically, we can\'t touch it, see it, or manipulate it using conventional means. You could, in principle, manipulate dark matter using gravitational forces. The problem is that the gravitational force is so weak that you need planet-sized masses in order to gravitationally manipulate human-sized objects. There remains much unknown about dark matter since it is so hard to detect and manipulate. Dark matter is not predicted or explained by standard particle physics theories but is a crucial part of the Big Bang model. What is the right hand thumb rule |
