    Fertilizers - These are man man made substances made by chemical salts.It is compact and easy to store and easy to transport.It does not provides humus to the soil. Manure - These are natural substances made by decomposition of plants and animals.It is voluminium and difficult to store and difficult to transport.It provides humus to the soil.

    The fertilizers are inorganic as well as manure is organic. Fertilizers are made with chemical and manureis the decomposition of plant waste , animal waste etc. Manure provides a lots of humus to soil where as fertilizers do not.Fertilizers are rich in plant nutrients such as phosphorus, potassium etc. But manure does not.

    A rational number is any number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Since q may be equal to 1, every integer is a rational number.

    Plants breathe through pores these structures are called stomata.Stomata are pores found on stems, leaves and other plant parts that control gas exchange. Essentially, these structures allow carbon dioxide to enter, and along with water, carry out photosynthesis in the presence of light, to produce glucose. Oxygen is released through the stomata as a waste product resulting from photosynthesis, and some water vapor also leaves through a process called transpiration.

    Ruminants are mammals that are able to acquire nutrients from plant-based food by fermenting it in a specialized stomach prior to digestion, principally through microbial actions. The word "ruminant" comes from the Latin ruminare, which means "to chew over again".

    The process typically requires the fermented ingesta (known as cud) to be regurgitated and chewed again. The process of rechewing the cud to further break down plant matter and stimulate digestion is called rumination.

    Mixed cropping, also known as inter-cropping or co-cultivation, is a type of agriculture that involves planting two or more of plants simultaneously in the same field.  Possible benefits of mixed cropping are to balance input and outgo of soil nutrients, to keep down weeds and insect pests, to resist climate extremes (wet, dry, hot, cold), to suppress plant diseases, to increase overall productivity and to use scarce resources to the fullest degree.

    Example of mixed cropping is that maize, beans, and curcurbits (squash and pumpkins).plants.  All three seeds are planted in the same hole. The maize provides a stalk for the beans to climb on, the beans are nutrient-rich to offset that taken out by the maize, and the squash grows low to the ground to keep weeds down and water from evaporating from the soil in the heat.

    When sodium reacts with water the solution release hydrogen gas. When we light a matchstick and bring near the solution it gives a pop sound

    1Thank You

    Vaishnavi Tiwari 8 years, 4 months ago

    Sodium is a metal which reacts vigorously with cold water it forming sodium hydroxide. It produce pop sound because hydrogen is actually a combustible gas . But when we try t burn it , it explodes . However when you produce hydogen in labotary , which is reactively less and put it on a burning splint it also explodes for POP sound . The very small explosion extinguishes the flame.

    Friction is the opposing force .

    1Thank You

    Amar Kumar 8 years, 4 months ago

    Ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races. The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. It achieves this by using at least two races to contain the balls and transmit the loads through the balls. In most applications, one race is stationary and the other is attached to the rotating assembly (e.g., a hub or shaft).

    Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.

    Differences between manures and fertilizers: 

    1. Manure is natural substance obtained by the decomposition of plant and animal remains by bacteria. Fertilizer is inorganic substances or compounds
    2. Manure provides humus to the soil. Fertilizer does not provide humus to the soil.
    3. Manure is less rich in plant nutrients. Fertilizers are rich in plant nutrients such as nitrogen, phosphorus and potassium. 
    4. Manure can be prepared in fields  Fertilizer is prepared in factories. 
    5. Manure is inconvenient to store and transport  Fertilizers are easy to store and transport
    6. Manure is absorbed slowly by plants .Fertilizers are absorbed readily by plants .
    7. Example of manure is  Green manure. Example of fertilizer is Urea
