Function of plant cell with animal cell |
| Answer» Plant cells\xa0have a\xa0cell\xa0wall, a large central vacuole, and plastids such as chloroplasts. The\xa0cell\xa0wall is a rigid layer that is found outside the\xa0cell\xa0membrane and surrounds the\xa0cell, providing\xa0structural\xa0support and protection. The central vacuole maintains turgor pressure against the\xa0cell\xa0wall.\xa0Cells\xa0carry out all the processes of the body including producing and storing energy, making proteins, replicating the DNA, and transportation of molecules through the body.\xa0Cells\xa0are highly specialized to carry out specific tasks. | |

What is difference between uniform linear motion and uniform circular motion ? Explain with example |
| Answer» The basic\xa0difference between uniform linear motion\xa0&\xa0uniform circular motion\xa0is.\xa0Uniform Linear Motion: Velocity is constant & thus it is a\xa0uniform motion. Acceleration is zero.\xa0Uniform Circular Motion: Velocity is not constant due to continuous change in Direction & thus it is not a\xa0uniform motion.\xa0An object is said to move in\xa0uniform linear motion\xa0, if it travels in straight line and covers equal distance\xa0in equal time interval.\xa0Uniform circular motion: 1. When a body moves in\xa0circular\xa0path with\xa0uniform\xa0speed , it\'s\xa0motion\xa0is called\xa0uniform circular motion. | |

Define thomson model of an atom |
| Answer» In 1897, a British physicist, J. J. Thomson did a series of experiments, the conclusions of which led to a new atomic theory.Thomson proposed a model of the atom that was like a watermelon.In a watermelon there is a red edible part in which black seeds are embedded.Thomson said that the atom is a spherical mass like the red part of the watermelon. This is the positively charged part of the atom.He further compared the seeds embedded in the red part to negatively charged particles, which he called electrons.He proposed that the positive and negative charges are equal in magnitude and so the atom as a whole is neutral.The greatest contribution made by Thomson was the experimental proof for the existence of electrons, the negatively charged particles in the atom.\xa0For this discovery of electrons, Thomson was awarded the Nobel Prize in the year 1906.\xa0But, his model could not explain the results of experiments carried out by other scientists like Rutherford and Bohr. | |

Whatever is division of labour??? |
| Answer» Division of labour refers to the method of organising production where the work required to produce a product is divided into different specialized tasks with different workers specializing in each task.The four ways in which division of labour will influence production in an economy are as follows:i. Quality of production improves - Division of labour leads to an increase in the efficiency of labour which further leads not only to an increase in the quantity of output but also to an improvement in the quality of the produced goods and services.ii. Large scale production - Division of labour makes large scale production possible. Indeed, scale production requires division of labour. If a car manufacturing company, for instance wishes to make 10000 cars in a year but does not introduce division of labour in its factory, it will have to employ so many workers that it will not be an economically viable company. It is by virtue of division of labour that the company can produce 10000 cars per year with a reasonable number of workers.iii. Reduced average cost - Since division of labour increases total output, even with an unchanged number of labourers, the average cost of producing a commodity falls. This is a social advantage. Society can produce goods by incurring lower average cost of production.iv. Lower prices of output - The reduced average cost of the products leads to reduced prices of the outputs in the market. As a result, consumers are benefitted. | |

Why we eat food? |
|
Answer» Food is a source of nutients which provide us energy helping us in our daily works The food that we eat is broken down to simpler constituents which are then absorbed and utilised by the body. The nutrients are used to release energy whereby the various functions of our body like movement, thinking, maintaining homeostasis etc. can be carried out. In addition we need nutrients for building the various parts of our body, thus enabling the growth and repair of our body.Answered |

State two characteristics of matter demonstrated by: (1) diffusion,(2) brownian motion |
|
Answer» Diffusion- particles of matter have space between them . Brownian motion - particles of matter move continuesly Diffusion:Diffusion is nothing but the movement of molecules from it\'s higher concentration to loyer concentration.OrThe sreading out and mixing of aone substance into another substance due to the motion of its particles is called diffusion.Brownian motion :The zig-zag movement of small particles suspended in a liquid or a gads is called Brownian motion.Brownian motion tells us that the particles are tiny nature and the particles of a matter are constantly moving. |

Explain mitosis and meiosis |
|
Answer» thanks yogita \tMeiosis is the form of nuclear cell division that results in daughter cells that have one half the chromosome numbers as the original cell.\tIn organisms that are diploid, the end result is cells that are haploid. Each daughter cell gets one complete set of chromosomes, i.e., one of each homologous pair of chromosomes.\tIn humans, this means the chromosome number is reduced from 46 to 23.\tThe only cells that undergo meiosis will become sperm or eggs.\t\tMitosis is a continuum process of cell division which occurs in all types of living cells.\tMitosis\xa0involves\xa0four basic phases –\xa0prophase, metaphase, anaphase and telophase.\tMitosis is the process where the division of cell occurs by asexual reproduction.\tIn mitosis, the nuclear membrane is broken down, spindle fibres (microtubules) attach to the chromatids at the centromere and pull apart the chromatids. |

Tell me about sexual reproduction |
| Answer» In sexual reproduction, the *** cells of one parent fuses with the *** cell of the other parent to form a new cell called zygote which develops into a new organism. The production of a new organism from two parents by making use of their *** cells is called sexual reproduction.\xa0Fertilization is the first step in sexual reproduction. When sperms come in contact with an egg, one of the sperms may fuse with the egg. Such fusion of the egg and the sperm is called fertilization. During fertilization, the nuclei of the sperm and the egg fuse to form a single nucleus which results in the formation of a fertilized egg or zygote. It is due to fertilization that the new individual inherits some characteristics from the mother and some from the father. | |

Ice floats on water.why? |
|
Answer» Ice floats on water because it is less dense than water. Ice has an open structure. Ice have more intermolecular space between particles than water. Thus, Ice floats on the water ? The mass per unit volume of a substance is called density (density = mass/volume). As the volume of a substance increases, its density decreases.Liquids have lower density than that of solids. Water is also a liquid so it should also have less density than that of solid that is ice.Though ice is a solid, but it has a cage like structure hence there are large number of empty spaces between its particles. These spaces are larger as compared to the spaces present between the particles of water. Thus for a given mass of water, volume of ice is greater than that of water. Hence, the density of ice is less than that of water. A substance with lower density than water can float on water. Therefore, ice floats on water. |

Did peroxisomes present in both plant and animal cells |
| Answer» Peroxisomes, sometimes called microbodies are generally small (about 0.1 – 1.0 µm in diameter) organelles\xa0found\xa0in\xa0animal\xa0and\xa0plant cells. They can vary in size within the same organism. They are called\xa0peroxisomes\xa0because they all produce hydrogen peroxide.\xa0Peroxisomes absorb nutrients that the cell has acquired. They are very well known for digesting fatty acids. They also play a part in the way organisms digest alcohol (ethanol). Because they do that job, you would expect\xa0liver cells\xa0to have more peroxisomes than most other cells in a human body. | |

Diffusion takes place in solid to solid ,liquid to liquid ,gas togas |
| Answer» Diffusion in gas:Diffusion takes place most rapidly in gasses.The particles of gas have more kinetic energy due to that they move with high speed. Because of the movement of particles with high speed gas diffuses most rapidly.Example:\xa0Mixing of gases in airDiffusion in liquid:Diffusion takes place in liquids. The rate of diffusion is less in liquid than that of gases.The particles of liquid have enough movement because of kinetic energy for diffusion. When two liquids are kept together they are mixed because of the diffusion.For example; When salt solution is kept in water this makes whole the solution salty after some time. This happens because of diffusion in liquids.Diffusion in solid:Diffusion takes place with slowest rate in the case of solids. The rate of diffusion is almost negligible in solids.Since the particles of solid have lowest kinetic energy so they do not move. Hence, diffusion takes a long time in the case of solid.Example – Some time we observe that the marks of chalk on the black board could not be wiped out easily after a long time. This happens because of the diffusion of particles of chalks with the particles of black-board and marks of chalk could not be wiped out. | |

What is the difference between mitosis and miosis |
| Answer» Mitosis\xa0gives identical cells to each other and to the mother cell, while\xa0meiosis\xa0leads to genetic variation due to crossing over and independent assortment.\xa0Mitosis\xa0gives nuclei with the same number of chromosomes as the mother cell while\xa0meiosis\xa0gives cells with half the number.\xa0The fundamental\xa0difference between mitosis and meiosis\xa0is that\xa0mitosis\xa0produces two daughter cells with the same number of chromosomes as the parent cell.\xa0Meiosis\xa0results in four daughter cells harboring only half of their parent\'s chromosomes, which underwent recombination. | |

How to calculate speed of planets? |
|
Answer» Wo puch raha hai how to calculate itna bada भाषण likhna nahi puch raha Mercury\xa0is the fastest planet, which speeds around the sun at 47.87 km/s. In miles per hour this equates to a whopping 107,082 miles per hour. 2. Venus is the second fastest planet with an orbital speed of 35.02 km/s, or 78,337 miles per hour. The orbital\xa0speed\xa0can be found using v = SQRT(G*M/R). The R value (radius of orbit) is the earth\'s radius plus the height above the earth - in this case, 6.77 x 106\xa0m.\xa0This means that\xa0Jupiter\xa0has the shortest days of all the planets in the solar system. Venus is the slowest - it rotates once every 243 days —- by far the slowest rotation period of any of the major planets. A Venusian sidereal day thus lasts more than a Venusian year (243 versus 224.7 Earth days). |

which of the following diffuses faster? Water vapour,wax or ,ethyl alcohol .And why ? |
| Answer» Water vapour diffuses faster than ethyl alcohol or wax.Explanation:When the matters of two different types of particles of are intermixing on their own, this is called as diffusion. The diffusion rate increases with increase in the diffusion temperature of the substance. It is a natural process. Diffusion process occur place in the “solid, liquid and gas”. Since water vapour is in the state of gas, the kinetic energy is maximum between the particles in the gases. Therefore, the movement of particles is in high speed and its movement has no fixed shape and volume. Gases diffuse faster than solid and liquid. The inter molecular space in gas is more and inter molecular forces are less. | |

what is the acceleration of the body moving with uniform velocity? |
|
Answer» The rate of the change of the velocity of an object is called acceleration. If the velocity of an object is uniform, which means there is no change in the velocity, then the acceleration would naturally be zero. The ‘acceleration of a body’ moving with uniform velocity will be zero as acceleration is defined as the “rate of change of velocity” per unit time. So if the body exhibit uniform velocity, then the rate of ‘change of velocity’ (dv = 0) will be zero. Thus the acceleration formula,a= dv/dt = 0Thus the acceleration of the body will also be zero. As the final and initial velocity have same magnitude the acceleration will be zero.\xa0 Zero |

Why distance is called magnitude of displacement? Unit of displacement is s or ∆s? |
| Answer» \'Magnitude of displacement\' is a technical way of saying \'distance, as measured directly between the start point and the end point\'. As it includes no directional information it is a \'scalar\' quantity rather than a \'vector\'. Example, imagine two friends live on opposite sides of a lake.\xa0This makes\xa0displacement\xa0a vector quantity because it incorporates both movement, magnitude and direction. In the shorthand of physics,\xa0displacement\xa0is written as Δs. \'Delta\' is a Greek letter shaped like a triangle and it\'s\xa0used\xa0to represent \'change in. \' The \'s\' stands for spatial location. | |

Effect of manure,fretilizer and polythene on plant population |
| Answer» Manure\xa0is organic matter used as fertilizer in agriculture.\xa0Manures\xa0improve the fertility of the soil by adding organic matter and lots of nutrients, such as nitrogen that is trapped by bacteria in the soil. Higher organisms then feed on the fungi and bacteria in a chain of life.\xa0Fertilizers\xa0provide essential nutrients to\xa0plants\xa0in form of soluble salt compounds, and directly\xa0affect plant growth. Soil amendments indirectly\xa0affect plants\xa0by improving the physical or chemical properties of soil. ...\xa0Fertilizers\xa0also add nutrients that are essential to\xa0plants\xa0in the form of soluble salt compounds.\xa0Manures\xa0contribute to the\xa0fertility\xa0of the\xa0soil\xa0by adding organic matter and\xa0nutrients, such as nitrogen, that\xa0are\xa0trapped by bacteria in the\xa0soil. Kinds of\xa0manure\xa0: Green\xa0manure, compost or vermicompost.\xa0Manure\xa0helps in enriching\xa0soil\xa0with\xa0nutrients\xa0and organic matter and thus, increases\xa0soil fertility.\xa0Some of these\xa0impacts\xa0include algae blooms causing the depletion of oxygen in surface waters, pathogens and nitrates in drinking water, and the emission of odors and gases into the air. Nutrients from manure and\xa0fertilizers\xa0enter lakes and streams through runoff and soil erosion. | |

A gas can exert pressure on the walls of the container. Assign reason. |
|
Answer» Yes its right my too same When the fast moving gas particles hit the walls of the container , they exert a pressure which is called gas pressure . Thus , a gas exerts pressure on the walls of the container . the pressure exerted by a gas is due to the collision of the fast moving as particles against the walls of the container when a gas is put in an Empty container, it quickly spreads throughout the container and fills it completely. If a gas is heated the particles of gas start moving faster and faster . |
