 Osmoregulation Osmoregulation is the process of maintaining salt and water balance (osmotic balance) across membranes within the body. The fluids inside and surrounding cells are composed of water, electrolytes, and nonelectrolytes. An electrolyte is a compound that dissociates into ions when dissolved in water. A nonelectrolyte, in contrast, does not dissociate into ions … Read more

 Food preservatives Food preservatives constitute a group of compounds of widely different molecular structures; they are organic and inorganic substances with different functional groups and tendencies to form ions. There are no procedures that are generally applicable to the analysis of preservatives as a class of food additive; the procedures are specific to … Read more

The movement of gas, water, and nutrients in plants are carried out in components. They take in carbon … Read more

Terminology related with Sound Amplitude Amplitude, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is equal to one-half the length of the vibration path. The amplitude of a pendulum is thus one-half the distance that the bob traverses in moving from one … Read more

 Rubbers There are many different kinds of rubber, but they all fall into two broad types: natural rubber (latex—grown from plants) and synthetic rubber (made artificially in a chemical plant or laboratory). Commercially, the most important synthetic rubbers are styrene butadiene (SBR), polyacrylics, and polyvinyl acetate (PVA); other kinds include polyvinyl chloride (PVC), … Read more

 Synthetic fibers (nylon and rayon),, polystyrene Synthetic fibers are made from raw materials such as petroleum, based on chemicals or petrochemicals. These materials are polymerized into a long, linear chemical with different chemical compounds and are used to produce various types of fibers. Synthetic fibers account for about half of all fiber usage, … Read more

8 Aviation Almost all modern aircraft are fitted with multiple GPS receivers. This provides pilots and sometimes passengers with a real-time aircraft position and map of each flight’s progress. GPS also allows airline operators to pre-select the safest, fastest and most fuel-efficient routes to each destination, and ensure that each route is followed as closely … Read more
