Why it is said that nitrogen is very important for us |
|
Answer» It is said because humans are depend on plants and animals and animals are depend upon nitrogen to produce protein which is consumed by animals and then animals and directly plants are consumed by us. The nitrogen is very important for us.if there will be no nitrogen and anyone starts fire at some small place it will spread from there to other places and all the earth catches fire and all thigs will burnt and all will finished and we goes to stone from 21st sanctuary it is said that nitrogen is very important for us as all human beings depend on plants and plants need nitrogen for preparing their food ultimately nitrogen is important for human beings |

Write down the names of cell organelles and describe the funchions of any two |
| Answer» A small organ-like structure present inside the cell is called a cell organelle. It has a particular structural makeup and performs a specific function. Depending upon the presence or absence of membrane, cell organelles can be classified into three categories, namely:\tWithout membrane: Some cell organelles like ribosomes are not bounded by any membrane. They are present in prokaryotic as well as eukaryotic organisms.\tSingle membrane-bound: Some organelles are bounded by a single membrane. For example, vacuole, lysosome, Golgi Apparatus, Endoplasmic Reticulum etc. They are present only in a eukaryotic cell.\tDouble membrane-bound: Cell organelles like mitochondria and chloroplast are double membrane-bound organelles. They are present only in a eukaryotic cell. | |

Law of conservation |
| Answer» According to law of conservation of momentumWhen two or more bodies acts upon each other their total momentum remains constant provided no external forces are actingThe law of conservation of energy states that energy can neither be created nor be destroyed. It may be transferred from one of its forms to the other. If you take all forms of energy into account, the total energy of an isolated system always remains constant. | |

Define cell with type |
| Answer» All living organisms, including plants, animals, bacteria and fungi, are made up of cells. Cells are the smallest parts of all living organisms.Cells are similar to small factories with different laborers and departments that work all the time to make life possible. Various kinds of cells perform different functions like protein synthesis and energy production.There are two major kinds of living organisms based on their cellular structure namely: prokaryotes and eukaryotes.\tProkaryotes are made up of cells with no nucleus. They all are single-celled microorganisms including archaea, bacteria and photosynthetic blue-green algae which are also known as cyanobacteria.\tEukaryotes consists of cells with a nucleus. This large category involves all plants, fungi (such as molds, yeast, and mushrooms), protozoa (Plasmodium falciparum and parasite that cause malaria) and animals. The plasma membrane is responsible for monitoring the transport of nutrients and electrolytes in and out of the cell and also responsible for cell to cell communication. | |

Derivation of law of conservation of energy |
| Answer» Law of conservation of energy states that the energy can neither be created nor destroyed but can be transformed from one form to another.Let us now prove that the above law holds good in the case of a freely falling body.Let a body of mass \'m\' placed at a height \'h\' above the ground, start falling down from rest.In this case we have to show that the total energy (potential energy + kinetic energy) of the body A, B and C remains constant i.e, potential energy is completely transformed into kinetic energy.Body of mass m placed at a height hAt A,Potential energy = mghKinetic energy = 0 [the velocity is zero as the object is initially atrest]\xa0Total energy at A = Potential energy + Kinetic energy.Total energy at A = mgh …1At B,Potential energy = mgh= mg(h - x) [Height from the ground is (h-x)]Potential energy = mgh - mgxKinetic energy = ½ mv2The body covers the distance x with a velocity v. We make use of the third equation of motion to obtain velocity of the body.Here, u=0, a=g and s=xKinetic energy = mgx\xa0Total energy at B = Potential energy + Kinetic energyTotal energy at B = mgh …2At C,Potential energy = m x g x 0Potential energy = 0Kinetic energy = ½ mv2The freely falling body has covered the distance h.Here, u=0, a=g and s=hKinetic energy = ½ mv2Kinetic energy = mgh\xa0Total energy at C = Potential energy + Kinetic energyTotal energy at C = mgh …3It is clear from equations 1, 2 and 3 that the total energy of the body remains constant at every point. Thus, we conclude that law of conservation of energy holds good in the case of a freely falling body. | |

What is Electrovalency ? |
|
Answer» Electrovalency: The number of electrons lost or gained by an atom to get stable electronic configuration in forming ionic bond is called its electrovalency.Ex: In getting Neon gas configuration Sodium (Na) loses one electron to Chlorine. Thus electrovalency of Sodium is 1 The valency of an ion positive equal to the negative charge is known as Electrovalency. |

What is meaning of homogeneous mixture |
|
Answer» A solution is a homogeneous mixture composed of two or more substances. In such a mixture, a solute is a substance dissolved in another substance, known as a solvent. The particles of solute in a solution cannot be seen by the naked eye. A solution does not allow beams of light to scatter. The solute from a solution cannot be separated by filtration (or mechanically).It is composed of only one phase. A mixture which has uniform composition through out such mixtures are called homogeneous mixtures |
|
| 5493. |
Why are some elements chemically inert |
| Answer» Elements react to attain stability by completing octet of electrons, for which they lose, gain or share electrons depending upon their valency.However some elements like inert gases have a completely filled valence orbital. (e.g. Ne = 2,8), and hence are stable and do no need to lose/gain or share electrons, thus making them unreactive | |

What is meaning of heterogeneous mixture |
|
Answer» A heterogeneous mixture is simply any mixture that is not uniform in composition - it\'s a non-uniform mixture of smaller constituent parts. Using various means, the parts in the mixture can be separated from one another. Heterogeneous mixtureIt is a mixture in which the particle or substances are not evenly spread or distributed as shown in the above figure. This type of mixture can be easily converted to their original shape through chemical processes. Heterogeneous mixtures are also called as suspensions or colloids. The word ‘hetero’ means different.For example- Mud is a good example for colloids. If you mix some mud with water and keep it for few days, you can see that mud gets settled in the bottom of the container. Hence this shows that mud and water form a heterogeneous mixture. This kind of suspensions or colloids are visible to the naked eye. |

Three application of archimedes principal |
| Answer» 1. Fish float based on Archimedes\' principle. Most fish have an organ known as the swim bladder. When they want to rise, fish release gas into the swim bladder and increase their volume. As a result, they displace more water. The force of buoyancy acting on them increases. To come down, a fish empties the bladder to the required extent, reducing the volume and the force of buoyancy acting on it.2. A hot air balloon rises and floats due to the buoyant force (when the surrounding air is greater than its weight). It descends when the balloon\'s weight is higher than the buoyant force. It becomes stationary when the weight equals the buoyant force.The weight of the Hot-air balloon can be controlled by varying the quantity of hot air in the balloon.3. A hydrometer uses Archimedes’ principle to determine the density of any liquid. | |
