Sugaring is a food preservation method similar to pickling. Sugaring is the process of desiccating a food by first dehydrating it, then packing it with pure sugar. This sugar can be crystalline in the form of table or raw sugar, or it can be a high sugar density liquid such as honey, syrup or molasses. Like salt water also has an osmotic effect i.e. when foods are placed in a concentrated sugar solution water is drawn out of the cells of foods and microorganisms so that microorganisms can no longer survive. ... Sugar is then added to the fruit to prevent the regrowth of bacteria.

The modern methods of irrigation help us to use water economically. The two main modern methods of irrigation are:
- Sprinkler system – In sprinkler system of irrigation, a main pipe is laid in the fields to which perpendicular pipes are joined at regular intervals. When water from a tube-well is allowed to flow through the main pipeline under pressure with the help of a pump, it escapes from the rotating nozzles and gets sprinkled on the crops. This method of irrigation is more useful for the uneven land and sandy soil where sufficient water is not available.
- Drip system – In the drip system, there is a network of narrow pipes with small holes in the fields. When water falls through these narrow pipes, it falls drop by drop at the position of the roots of the plants. There is no run-off or wastage of water. This technique is the best technique for watering fruit plants, trees and gardens.

Heat of fusion of a substance is the change in its enthalpy by providing energy, typically heat, to a specific quantity of the substance to change its state from a solid to a liquid keeping pressure constant.
The heat of fusion of a sample is the measure of the amount of heat that needs to be introduced to convert its crystalline fraction into the disordered state. It is uniquely dependent upon the degree of crystallinity of the substance and the theoretical heat of fusion of a sample which is 100% crystalline.

Hormones are chemical substances that act like messenger molecules in the body. After being made in one part of the body, they travel to other parts of the body where they help control how cells and organs do their work. For example, insulin is a hormone that's made by the beta cells in the pancreas. The main function of endocrine glands is to secrete hormones directly into the bloodstream. Hormones are chemical substances that affect the activity of another part of the body (target site). In essence, hormones serve as messengers, controlling and coordinating activities throughout the body.
