Why there are half numbers of chromosomes in the daughter cell of meiosis cell division |
| Answer» The purpose of meiosis is to shuffle genetic information and cut the cellular chromosome number in half, from chromosomes to 23 chromosomes. In this way, when an egg and sperm cell combine during fertilization, the appropriate amount of unique genetic information from each parent. The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell. Meiosis has both similar ities to and differences from mitosis, which is a cell division process in which a parent cell produce two identical daughter cells. | |

Can gas to solid be called sublimation ? Justify with reason |
|
Answer» Thanks The reverse process of sublimation is\xa0deposition\xa0or desublimation, in which a substance passes directly from a gas to a solid phase.\xa0Sublimation has also been used as a generic term to describe a solid-to-gas transition (sublimation) followed by a gas-to-solid transition (deposition).\xa0While a transition from liquid to gas is described as\xa0evaporation\xa0if it occurs below the boiling point of the liquid, and as\xa0boiling\xa0if it occurs at the boiling point, there is no such distinction within the solid-to-gas transition, which is always described as sublimation.The term\xa0sublimation\xa0refers to a\xa0physical change\xa0of\xa0state\xa0and is not used to describe the transformation of a solid to a gas in a chemical reaction. For example, the dissociation on heating of solid\xa0ammonium chloride\xa0into hydrogen chloride and ammonia is\xa0not\xa0sublimation but a chemical reaction. Similarly the combustion of candles, containing\xa0paraffin wax, to\xa0carbon dioxide\xa0and\xa0water vapor\xa0is\xa0not\xa0sublimation but a chemical reaction with oxygen.Sublimation is caused by the absorption of heat which provides enough energy for some molecules to overcome the\xa0attractive forces\xa0of their neighbors and escape into the vapor phase. Since the process requires additional energy, it is an\xa0endothermic\xa0change.\xa0 |

Write short note on: (1)Epithelial cell of plants |
| Answer» All layers and organs in the body are lined by a group of tissues called epithelial tissues which are commonly referred to as epithelium. They cover the surface of all internal as well as external organs. Epithelial tissue is highly permeable. Thus, it plays a significant role in the exchange of substances across the cells and helps in maintaining the osmoregulation. Depending on the number of layers of cells it is composed of, epithelium has been divided into simple epithelium and compound epithelium. The main functions of epithelial tissue are protection, secretion, absorption, and sensation. | |

Write the function of gene? |
|
Answer» Genes are present in the nucleus of a cell and is responsible for the transfer of hereditary characters from one generation to another. \tGenes control the functions of DNA and RNA.\tProteins are the most important materials in the human body which not only help by being the building blocks for muscles, connecting tissue and skin but also takes care of the\xa0enzymes\xa0production.\tThese enzymes play an important role in conducting various chemical processes and reactions within the body. Therefore, protein synthesis is responsible for all activities carried on by the body and are mainly controlled by the genes.\tGenes consist of a particular set of instructions or specific functions. For example, globin gene was instructed to produce haemoglobin. Haemoglobin is a protein that helps to carry oxygen in the blood. |

How rest and motion relative term |
|
Answer» An object which does not change its position with respect to time is said to be in rest. Rest and motion are the relative terms because they depend on the observer\'s frame of reference.If an observer is at rest in his or her own frame of reference , but he may be moving in other observer\'s frame of reference. So if two different observers are not at rest with respect to each other, then they too get different results when they observe the motion or rest of a body. |

What is thhe difference between boiling and evaporation |
|
Answer» Boiling is a bulk phenomenon. Particles fron bulk (whole) of the liquid change into vapour state whereasEvaporation is a surface phenomenon. Particles from the surface gain enough energy to overcome the forces of attraction present in the liquid and change into vapour state. 1. Boiling is vaporisation of liquid into gas due to continuous heating. Most of the time it is not a natural process.Evaporation on the other hand is a natural process and it is similar to boiling , but the liquid form changes into gaseous form when there is a increase in either temperature or pressure or both.2. Boiling happens when the temperature reaches to the boiling point.\xa0In Evaporation the temperature does not need to reach to boiling point3.\xa0\tBubble formation is visibleWhere as Bubbles do not form in evaporation\t |

How is golgi apparatus different from endoplasmic reticulum? |
| Answer» Golgi\xa0bodies are an arrangement of few fluid-filled dishes whereas\xa0Endoplasmic reticulum\xa0is a network of tubules and vesicles.\xa0Golgi apparatus\xa0sorts, modifies, and delivers the components in a cell, whereas\xa0Endoplasmic reticulum\xa0is much a structurally aiding organelle for metabolic activities.\xa0Ribosomes, the\xa0endoplasmic reticulum\xa0and the\xa0Golgi apparatus\xa0are\xa0related\xa0to each other through their involvement in protein synthesis and transport. ... The primary role of the\xa0Golgi apparatus\xa0is to modify the proteins and encase them into vesicles. From here they are transported to the various parts of the cell. | |

Which matter can retain their properties? |
| Answer» Solid matter is composed of tightly packed particles. A solid will retain its shape; the particles are not free to move around.Liquid matter is made of more loosely packed particles. It will take the shape of its container. Particles can move about within a liquid, but they are packed densely enough that volume is maintained.Gaseous matter is composed of particles packed so loosely that it has neither a defined shape nor a defined volume. A gas can be compressed. | |
| 8895. |
How states of matter can be changed by changing the temperature and pressure |
| Answer» Matter changes from one state to another by change in temperature and pressure. For e.g. solids on heating changes to liquid, liquid on further heating changes to gases. In same manner gases on compression means on applying pressure changes to liquid again. | |

Explain the function and structure of plasma membrane |
| Answer» The outer boundary of the cell is called the plasma membrane. The cytoplasm lies inside it. It is a living, thin, delicate, elastic, selectively permeable membrane.Functions:\tIt separates the contents of the cell from its external environment.\tThe plasma membrane allows or permits the entry and exit of some materials in and out of the cell.\tIt also prevents movement of some other materials.The cell membrane is called a selectively permeable membrane because it permits the entry and exit of some materials in the cell.\xa0The plasma membrane is flexible and is made up of organic molecules called lipids and proteins. According to fluid mosaic model, plasma membrane is made up of a bilayer of phospholipids. There are two types of protein molecules: Intrinsic Proteins, which completely covers the lipid bilayer and Extrinsic Proteins, which occur either on the outer surface or on the inner surface of the lipid membrane.The fluid mosaic membrane has been described as “a number of protein icebergs floating in the sea of lipids”. | |
