Describe the digestion process of Amoeba |
|
Answer» My answer- Digestion process of amoeba-1) Amoeba is a unicellular organism which live in water.2) When food particle come closer to Amoeba, it engulf the food particle with the help of pseudopodia.3) By the process of diffusion, food is entered in cytoplasm, this process is called (ingestion).IMPORTANT POINT-*4)A temporary vacuole is created in which food is (digested).5) Digested food is (absorbed) and (assimilated) in the cytoplasm. 1) Amoeba is a unicellular organism.It obtains its food with the help of pseudopodia.2) It encloses food to form food vacuole by phagocytosis(ingestion).3) The food vacuole has certain enzyme which digests the food (digestion).4) The digested nutrients diffuse into the cytoplasm(absorption) and are used up( assimilation).5) The undigested food is thrown out of its body by exocytosis( excretion).\xa0This is the process of digestion in Amoeba, a unicellular eukaryote. |

What are the differences between autotrophic nutrition and hetrotropic nutrition |
|
Answer» Hetrotrophs is depend on others for food like lion and Autotrophes are self dependent for food like green ?plants Autotrophic nutrition: In Greek auto means self and trophic means nutrition so it is the nutrition in which organisms make their own food with the help of inorganic material available in their environment. Where as . Heterotrophic: In Greek hetero means other and trophic means nutrition so it is a nutrition in which organisms depend on other organisms (autotrophs) for their food In autotrophic kind of nutrition organisms prepare their own food eg. green plants In heterotrophic nutrition organisms are dependent on others for food eg. human beings and animals. Auto means when organism prepared their own food like green plant .Hetero when organism depends on other for food. |

How the speed of the ball is measured in cricket |
| Answer» Measuring the velocity of the ball through Radar Guns or Speed Guns is\xa0like measuring the speed of the moving car. This technique was\xa0discovered in 1947 by "John Baker". Speed gun works on the principle of Doppler Effect. This Speed Gun has a receiver and a transmitter.The Speed Gun is placed on a high pillar near the Sight screen, from which Speed Gun sends radio wave in the direction of the pitch and calculates the speed of any object on the pitch.\xa0OrRadar Gun, which\xa0works on a similar principle of SONAR, catches the echo of Radio waves as the ball travels through the air, and uses a principle called "Doppler Shift".The information obtained through Speed Gun is inserted into image processing software, which identifies the ball between other objects on the pitch and displays the speed of the ball. | |

Can u explain heating effect of electric current for 5 marks question? |
| Answer» When current flows through a conductor, heat energy is generated in the conductor. The heating effect of an electric current depends on three factors:★The resistance, R of the conductor. A higher resistance produces more heat.★The time, t for which current flows. The longer the time the larger the amount of heat produced★The amount of current, I. the higher the current the larger the amount of heat generated.Hence, the heating effect produced by an electric current, I through a conductor of resistance, R for a time, t is given by H = I2Rt. This equation is called the Joule’s equation of electrical heating. | |

Explain the process of break down of glucose in a cell. |
| Answer» Glucose is broken down into a three carbon molecule called pyruvate in the cell cytoplasm. Pyruvate is further broken down by different ways to provide energy in various organisms.i.In yeast cells, during fermentation, pyruvate is converted into ethanol and carbon dioxide in the absence of oxygen.ii. In mitochondria, breakdown of pyruvate takes place in presence of oxygen to give rise three molecules of carbon dioxide and water.iii. Sometimes, when there is lack of oxygen, especially during vigorous activity, in our muscles, pyruvate is converted into lactic acid.\xa0Concept insight:\xa0Students should know various types of respiration. | |

Sign convention for spherical mirror |
|
Answer» Thanks???? Cartesian Sign Convention:\xa0In the case of spherical mirror all signs are taken from Pole of the spherical mirror, which is often called origin or origin point. This sign convention is known as New Cartesian Sign Convention.Sign is taken as – (negative) from pole of a spherical mirror towards object along the principal axis. This means sign is always taken as – (negative) in front of a spherical mirror. For example; the distance of object is always taken as – (negative) in case of both types of spherical mirror, i.e. concave and convex mirrors.\tSign is taken as + (positive) behind the spherical mirror. For example if an image is formed behind the mirror, the distance of image is taken as + (positive) from pole along the principal axis.\tThe height of is taken as + (positive) above the principal axis and taken as – (negative) below the principal axis. Fig: Cartesian Sign ConventionSign in the case of concave mirror:\tSince, object is always placed in front of the mirror hence the sign of object is taken as negative.\tSince, the centre of curvature and focus lie in front of the concave mirror, so signs of radius of curvature and focal length are taken as negative in the case of concave mirror.\tWhen image is formed in front of the mirror, the distance of image is taken as – (negative) and when image is formed behind the mirror, the distance of image is taken as + (positive).\tHeight of image is taken as positive in the case of erect image and taken as negative in the case of inverted image.Sign in the case of a convex mirror:\tSince, object is always placed in front of the mirror hence the sign of object is taken as negative.\tSince, the centre of curvature and focus lies behind the convex mirror, so sign of radius of curvature and focal length are taken as + (positive) in the case of convex mirror.\tIn the case of convex mirror, image always formed behind the mirror, thus the distance of image is taken as positive.\tIn the case of a convex mirror, always an erect image is formed, thus the height of image is taken as positive. |

Derive ohm’s law. |
| Answer» Ohm’s law states that at a constant temperature, current I through a conductor between two points is directly proportional to the potential difference or voltage, V, across the two points.\xa0Thus, the ratio V: I is constant, and is called the resistance, R, of the conductor.\xa0In other words, V/I = constant = R, or V = IR, where R is a constant for the given metallic wire at a given temperature and is called its resistance.\xa0The S.I unit of Resistance is ohm.If the values of V are plotted against I on a graph paper, the graph is known as a V-I graph. As the temperature of a conductor rises, its resistance also increases. | |

Why respiration is considerd as an engiothermic reaction? Give an example |
|
Answer» Because when this process have so energy is released our cell is absorbed so during this pecess process happen energy is released therfore respiration is known as exothermic reaction. Because it burns in body and it gives a energy so respiration is called exothermic reaction Respiration is considered\xa0as\xa0exothermic reaction\xa0because energy is released in this process. Glucose combines with oxygen\xa0present\xa0in our cells to form carbon dioxide and water along with energy.\xa0Respiration is considered\xa0as\xa0exothermic reaction\xa0because energy is produced during this process. |
