Nutrition in amoeba?? explain. |
| Answer» \tAmoeba is a unicellular , omnivore organism that does not possess specialised organ for the process of nutrition .\tThe mode of nutrition in Amoeba is HOLOZOIC and takes place with the help of pseudopodia ( finger like structure ) .\tIt engulfs food when it comes in contact with its cell surface by ingestion .\tPseudopodia fuses over food particle to form food vacuole .\tDigestion in Ameoba is INTRACELLULAR in nature. Inside the food vacuole, complex food breaks into small soluble molecules , This process is called ABSORPTION .\tThe absorbed food is further ASSIMILATED by Amoeba to derive energy for growth.\t\xa0The undigested food material is removed by the cell membrane, which ruptures suddenly at any place and eliminates out the undigested food.\tThe process of throwing out undigested food is called EGESTION . | |

How does a solenoid behave like a bar magnet |
| Answer» When electric current flows through a solenoid, magnetic field is set up around the solenoid. The pattern of the magnetic field is same as that of magnetic field of a bar magnet. One end of the solenoid behaves as north pole and the other end of the solenoid behaves as south pole.To determine the north and south pole of a current carrying solenoid with the help of abar magnet, suspend it with a strong thread. Now bring the north pole of a bar magnet towards one end of the solenoid. If the solenoid attracts towards the magnet, then that face of the solenoid is south pole. If the bar magnet moves away from the solenoid, then that face of the solenoid is the north pole. | |

I dont khow science what can i do??? |
|
Answer» If you want a full revision through online lessons, I\'d reccommend VEDANTU youtube channel. Otherwise, you can read your textbook thoroughly, go throught the school notes and NCERT textbook questions and practice previous years papers. Also ask your teschers to correct those papers you are practicing so that you can know your weak areas. Practice physics numericals everyday. Diagrams are important in Biology, practice them repeatedly. Chemistry, practice balancing equations and uses of various salts and how they are manufactured. If you are thorough with all this, you\'ll rock your exams! All the best! Practice... practice and practice bcz practice makes man perfectBut nobody is perfect in the world so why do we practice? |

Write Three ways to produce magnetic field? |
|
Answer» Three methods of producing magnetic fields are as follows:(a) Magnetic field can be produced by placing a permanent magnet or a horse-shoe magnet at the place, where magnetic field is required.(b) Magnetic field is produced around a current carrying straight conductor or a current carrying coil.(c) A very good method to produce magnetic field is due to flow of current in a solenoid.

Explanation of phototropism |
|
Answer» The directional movement of a plant in response to light is called phototropism. The shoot responds by bending towards light and roots respond by bending away from light.This happens as follows:(i) When sunlight falls straight on the plant, the auxin hormone synthesised at the tip of the stem spreads uniformly down the stem and due to equal concentration of auxin, stem grows straight.(ii) When sunlight fells on only one side of the plant, the auxin diffuses towards the shady side of shoot. The concentration of auxin stimulates the cells to grow longer. Therefore, the stem appears to bend towards the source of light. Ok Phototropism is the movement of plant part towards light . Eg movement of leaves towards sunlight |

What is crystallisation and dry slaked lime |
|
Answer» Crystallization or crystallisation is the process by which a solid forms, where the atoms or molecules are highly organized into a structure known as a crystal. Some of the ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas. Before use, quicklime is hydrated, that is combined with water, called slaking, so hydrated lime is also known as slaked lime, and is produced according to the reaction: . Dry slaking is when quicklime is slaked with just enough water to hydrate the quicklime, but remain as a powder and is referred to as hydrated lime. Read ncert |

Explain the whole process of electrolysis of water. (Ch 1 chemical equations and reactions) |
|
Answer» Thanks Deepak DEFINITIONElectrolysis of water is the decomposition of water into oxygen and hydrogen gas due to the passage of an electric currentPROCESS- Water reacts at the anode to form oxygen and positively charged hydrogen ions (protons).-The electrons flow through an external circuit and the hydrogen ions selectively move across the PEM to the cathode.-At the cathode, hydrogen ions combine with electrons from the external circuit to form hydrogen gas. Anode Reaction: 2H2O → O2 + 4H+ + 4e- Cathode Reaction: 4H+ + 4e- → 2H2 |
