When iron is heated with Sulphur, iron sulphide is formed name the reaction |
|
Answer» Combination reaction. Combination reaction A combination reaction is one in which two or more substances react together to form a third substance which is the addition product of the two. Here there is an exchange of electrons between the two compounds. When solid iron ‘metal is heated’ with powder sulphur which is a non-metal iron sulphide is formed. Iron exhibits a variable valency of 2 and 3. Here it loses two electrons, on the other ‘hand sulphur’ gains these two electrons. And hence FeS is formed.Fe + S ⟶ FeS\xa0 Combination reaction |

All flesh is grass justify the statement |
| Answer» Every consumer whether it is an animal, fish or bird has a fix life span after the completion of which they die. Dead remains of these organisms are decomposed by the decomposes i.e converted into simple inorganic substances. These inorganic substances serve as raw material for photosynthesis of the plants . Hence flesh in any form finally becomes grass.\xa0A carnivore derives its nutrition from a herbivore; while a herbivore derives it from grass or plants. So, a carnivore receives its entire food from the plants via herbivorous animal to build their body muscles and other tissues, hence we can say that all the flesh of not only carnivores but herbivores and omnivores is grass or other plants.\xa0 | |

What is the significance of food chain??? |
|
Answer» Thx☺☺ Food chains describe the feeding relationship between the organisms of an ecosystem. The flow of energy from one species to another at various biotic levels forms a food chain. The successive levels in the food chains of a community are called as trophic levels. Various trophic levels in a food chain include producers, primary consumers, secondary consumers and tertiary consumers. *Food chain helps in studying feeding relationships between organisms. *Food chain also helps us to know how much energy we gain by consuming which food. *Food chain helps us to know energy flow from one trophic level to another trophic level. |

State two properties of magnetic lines of force |
|
Answer» Thanks to both of you ?? Magnetic lines of force have a number of important properties, which include: They seek the path of least\xa0resistance\xa0between opposite magnetic poles. In a single bar magnet as shown to the right, they attempt to form closed loops from pole to pole. They never cross one another.The magnetic lines of force has the following properties:1) Each line is a closed and continuous curve.2) They originate from the north pole and terminate at the south pole.3) They will never intersect each other.4) They are crowded near the poles where the magnetic field is strong.5) They affect the magnetic compass needle. Properties of Magnetic lines of force are as follows:(i) They flow from the south pole to the north pole within a material and north pole to south pole in air(ii) They never cross each other(iii) They all have the same strength(iv) Their density decreases(mainly they spread out) when they move from an area of higher permeability to an area of lower permeability(v) Their density decreases with increasing distance from the poles.(vi) The expansion of lines of magnetic field accrue in lateral position and contraction in longitudinal position. |

Uses of concave lens. |
|
Answer» ☺️1. Concave lens are used for correcting myopia or short- sightness.☺️2. Concave lens are used in flashlight to magnify the light produced by the bulb Concave LensesEyeglasses have one convex surface and one concave surface. Such glasses can bend the light by the right amount before it gets to the eyes.Concave lenses also make details look clearer. So they are often used together with convex lenses in ’optical systems’ to help clear up any details that are lost due to flaws in the convex lens. For example, many high quality telescopes and binoculars use concave lenses to improve the detail of the images they provide. |

Define parallel CONNECTION and series CONNECTION ? |
|
Answer» PARALLEL CONNECTION:- A parallel circuit is a closed circuit divided into two or more paths before recombining to complete the circuit. Each load connected in a separate path receives the full circuit voltage and the total circuit is equal to the sum of the individual branch currents.SERIES CONNECTION:- A series circuit is one in which every component is in a series connection. Therefore, a series circuit has the same current at all points in the circuit. The voltage drops across each component in the circuit sum to the source voltage. Only define these two ,l do not want the difference \tSeriesParallelThe same amount of current flows through all the componentsThe current flowing through each components combines to form the current flow through the source.In an electrical circuit, components are arranged in a lineIn an electrical circuit, components are arranged parallel with each otherWhen resistors are put in a circuit, the voltage across each resistor is different even though the current flow is the same through all of them.When resistors are put in this circuit, the voltage across each of the resistors is the same. And even the polarities are the sameIf one component breaks down, the whole circuit will burn out.Other components will function even if one component breaks down, each has its own independent circuitIf\xa0Vt\xa0it total voltage then it is equal to V1+V2+V3If\xa0Vt\xa0it total voltage then it is equal to V1=V2=V3\t |

Difference between flagella and cilia. |
| Answer» Cilia are short, hair-like structure, present in large numbers in a cell, while flagella are long, hair-like complex structure and are few per cell. Cilia and flagella are hair-like appendages, extending through the surface of the living cell, they differ in their mode of beating, size, and number. Cilia and flagella are the locomotory structure, which is the extension of the plasma membrane of the cell. Besides the locomotion, they also help in other processes like respiration, excretion, circulation, etc. They also take part in capturing food. These both are found in eukaryotic cells, but in prokaryotic cells only flagellaBoth of these appendages are found in eukaryotic cells, but in prokaryotic cells only flagella are present.
