Explain the nutrition in amobes |
| Answer» The mode of nutrition in Amoeba is holozoic.The various steps involved in the process of nutrition are:Ingestion: Amoeba ingests food with the help of its finger-like extensions, called pseudopodia. When a food particle approaches Amoeba, it forms pseudopodia around it and forms a food vacuole inside the Amoeba.Digestion: Various enzymes from the cytoplasm enter into the food vacuole and break them down into simple soluble molecules.Absorption: The simple soluble food is absorbed by cytoplasm of Amoeba from food vacuoles through the process of diffusion.Assimilation: Amoeba cell obtains energy from the absorbed food through respiration. This energy is utilised by Amoeba for its growth and repair of the body.Egestion: When a considerable amount of undigested food gets collected inside Amoeba, its cell membrane ruptures and throws out the undigested food. | |

A small drop of liquid is always spherical in shape. Why? |
|
Answer» Due to surface tension Falling\xa0drop\xa0of a\xa0liquid is always spherical in shape\xa0due to surface tension. The inward forces on the surface molecules of the\xa0liquid droplet\xa0tend to cause the surface to volume ratio as\xa0small\xa0as possible. Liquid drops\xa0are\xa0spherical\xa0because of surface tension. Hence when\xa0small\xa0amount of\xa0liquid\xa0is separated from rest in the form of\xa0drop, the whole amount of\xa0liquid\xa0gets in the most energy efficient\xa0shape\xa0i.e. sphere due to the attraction of atoms/molecules, which we call surface tension. |

How the law of floatation discovered? |
| Answer» Law of floatation\xa0is a special condition of Archimedes\' Principle which states that the weight of a floating body is equal to the weight of the displaced liquid.\xa0Legend says that\xa0Archimedes discovered\xa0the\xa0principle\xa0of displacement while stepping into a full bath. He realized that the water that ran over equaled in volume the submerged part of his body. Through further experiments, he deduced the above mentioned\xa0Archimedes\'\xa0principle. | |

What is the angle of deviation?? |
|
Answer» The\xa0angle of deviation\xa0is the\xa0angle\xa0between the direction of the refracted ray and the direction of the incident ray when a ray of light passes from one medium to another.\xa0The emergent ray is bent at an\xa0angle\xa0with the direction of the incident ray. This\xa0angle\xa0is called the\xa0angle of deviation. The phenomenon of splitting of white light into its constituent seven colours on passing through a glass prism is called dispersion of light.\xa0The smallest\xa0angle\xa0through which light is bent by an optical element or system. In a prism, the\xa0angle\xa0of\xa0deviation\xa0is a\xa0minimum\xa0if the incident and exiting rays form equal\xa0angles\xa0with the prism faces. The\xa0angle\xa0is important relative to prism spectroscopes because it can be easily determined. The angle of deviation is the angle between the direction of the refracted ray and the direction of the incident ray when a ray of light passes from one medium to another |

Value of volt in ammeter? |
| Answer» An\xa0ammeter\xa0is a\xa0measuring\xa0device used to\xa0measure\xa0the electric current in a circuit. A voltmeter is connected in parallel\xa0with\xa0a device to\xa0measure\xa0its\xa0voltage, while an\xa0ammeter\xa0is connected in series\xa0with\xa0a device to\xa0measure\xa0its current.\xa0The major difference between the\xa0ammeter\xa0and the\xa0voltmeter\xa0is that the\xa0ammeter\xa0measures the flow of current, whereas the\xa0voltmeter\xa0measures the emf or voltage across any two points of the electrical circuit.\xa0For example, an analog voltmeter with a ±3%\xa0accuracy\xa0is set to the 0 to 100-V range. Based on this\xa0accuracy, its pointer can be 3 volts (100 V x 0.03 = 3 V) below or above the true\xa0reading. If the true measured value is, for example, 90.0 V, the meter might\xa0read\xa0between 87 V and 93 V or ± 3.3% of\xa0reading. | |

Newton 2nd law of motion |
| Answer» Newton\'s second Law of Motion states that the rate of change of momentum is directly proportional to the force applied in the direction of force.For example; when acceleration is applied on a moving vehicle, the momentum of the vehicle increases and the increase is in the direction of motion because the force is being applied in the direction of motion. On the other hand, when brake is applied on the moving vehicle, the momentum of the vehicle decreases and the decrease is in the opposite direction of motion because the force is being applied in the opposite direction of motion. | |

Why is life carbon based molecule |
| Answer» Carbon forms the key component for all known life on Earth. Complex molecules are made up of carbon bonded with other elements, especially oxygen, hydrogen and nitrogen, and carbon is able to bond with all of these because of its four valence electrons. Carbon is abundant on earth. It is also lightweight and relatively small in size, making it easier for enzymes to manipulate carbon molecules. | |
