    Vaccines give you immunity to a disease without you getting sick first. They are made using killed or weakened versions of the disease-causing germ or parts of the germ (called antigens). For some vaccines, genetic engineering is used to make the antigens used in the vaccine. It’s much safer to get a vaccine than to get the disease it prevents. When you get a vaccine, your immune system responds to the vaccine the same way it would to the real germ. It: Recognizes the germ in the vaccine as being foreign. Responds by making antibodies to the germ in the vaccine, just as it would for the real germ. Remembers the germ and how to destroy it. That way, if you are ever exposed to the disease-causing germ in the future, your immune system will be able to quickly destroy it before it has a chance to make you sick. This is how you get immunity from vaccines.

    Water is one of the mostimportant inputs essential for theproduction of crops. Plants need it continuously during their life and in huge quantities. It profoundly influences photosynthesis, respiration, absorption, translocation and utilization of mineral nutrients, and cell division besides some other processes.

    Krish Patel 5 years, 4 months ago

    Water is used for transpiration carrier of nutrients from the soil to green plant tissues. Water forms over 90% of the plant body by green or fresh weight basis. Plants can synthesis food through photosynthesis only in the presence of water in their system. Water helps to maintain the turgidity of cell walls.

    Irrigation is artificial application of water to soil to ensure growth of agricultural crops.

    Water is very important for growth of plants as it helps in germination of seeds, absorption of dissolved nutrients, photosynthesis and temperature regulation.

    Irrigation is very much needed in India due to irregular distribution of rainfall. If agriculture is left dependent on rains, then it will suffer during the dry seasons of the year.

    A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull.

    Krish Patel 5 years, 4 months ago

    Aristotle famously represented a force as anything that causes an object to undergo “unnatural motion”. Sir Isaac Newton was one of the first scientists to study gravity and force. Any kind of force is just a push or a pull. It can be described as a push or pull on an object.

    a push of pull is called force or it arises due to interaction between two objects

    Purva Sharma 5 years, 4 months ago

    In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity.

    Sound waves are changes in pressure generated by vibrating molecules. The physical characteristics of sound waves influence the three psychological features of sound: loudness, pitch, and timbre. Loudness depends on the amplitude,or height, of sound waves. The greater the amplitude, the louder the sound perceived.

    D.pancreas

    There are islet cells of Langerhans in the pancreas. The β- cells produce insulin. This hormone is responsible for the regulation of the blood sugar levels. The negative feedback mechanism is used to regulate the synthesis of insulin. When blood glucose levels rise, insulin is secreted by the pancreas. The insulin works by lowering the blood glucose by increasing its uptake in cells. It also helps by stimulating the liver to convert glucose to glycogen, in which form it can be stored. When the level of blood decreases, there is signal send to the cells of the pancreas to stop secreting insulin.
