Desiccators are things we use to get moisture out of the air. They are used to keep things dry in closed packaging to preserve the packaged item(s). The little packets are frequently packed into electronic equipment at the factory to keep things nice 'til you open them up. The small packs are usually marked "do not eat" and commonly appear to be little white beads.

Why is calcium chloride used in dessicators?
Basically the purpose of desiccators is storage of samples free from moisture . so Calcium chloride is a hygroscopic (capable of absorbing moisture) ,so we are using this in desiccators. and it is sometimes also called a drying agent.
Function that performs a mathematical function against a group of records?
Aggregate function
What is the function of amoeba?
it does not have any function
What is a composite function?
This is a combination of two functions, where you apply the first function and get a result and then fill that answer into the second function. OR These are what you get when you take the output of one function and use it to solve the output of the next function.
Does the principle of complementarity of structures and function means that the structure of a part reflects its fuction?
Function reflects structure and structure determines function

What is a dessicator and what are its uses and how does it look?
Desiccators are sealable enclosures containing desiccants used for preserving moisture-sensitive items. A common use for desiccators is to protect chemicals which are hygroscopic or which react with water from humidity. The contents of desiccators are exposed to atmospheric moisture whenever the desiccators are opened. It also requires some time to achieve a low humidity. Hence they are not appropriate for storing chemicals which react quickly or violently with atmospheric moisture such as the alkali metals. Aglovebox or Schlenk-type apparatus may be more suitable for these purposes. Desiccators are sometimes used to remove traces of water from an almost-dry sample. Where a desiccator alone is unsatisfactory, the sample may be dried at elevated temperature using Abderhalden's drying pistol. in laboratory use, the most common desiccators are circular, and made of heavy glass. There is usually a removable platform on which the items to be stored are placed. The desiccant, usually an otherwise-inert solid such as silica gel, fills the space under the platform. A stopcock may be included to permit the desiccator to be evacuated. Such models are usually known as vacuum desiccators. When a vacuum is to be applied, it is a common practice to criss-cross the vacuum desiccator with tape, or to place it behind a screen to minimize damage or injury caused by an implosion. To maintain a good seal, vacuum grease is usually applied to the flanges.
What is a desicator and how is it used?
Desiccators are sealable enclosures containing desiccants used for preserving moisture-sensitive items such as cobalt chloride paper for another use. A common use for desiccators is to protect chemicals which are hygroscopic or which react with water from humidity.
Can you give me a technical description of a desiccator?
Here is a description of the function of a desiccator, this is about as technical as it gets Desiccators are sealable enclosures containing desiccants used for preserving moisture-sensitive items. A common use for desiccators is to protect hygroscopic (Water Attracting) items such as honey, glycerin, ethanol, methanol; from humidity. In laboratory use, the most common desiccators are circular, and made of heavy glass although plastic desiccators such as polycarbonate are available. There is usually a removable platform on which the items to be stored are placed. The desiccant, usually an otherwise-inert solid such as silica gel, fills the space under the platform. By selecting different drying agents for the lower chamber, the humidity in the desiccator can be adjusted from very moist to bone dry. This will enable samples kept inside to be held at the optimum humidity for the application at hand. The high surface area of silica gel absorbs any moisture present within the chamber, thus keeping the items dry. A stopcock (Valve / tap) may be included to permit the desiccator to be evacuated. (Air removed) Such models are usually known as vacuum desiccators. To maintain a good seal, vacuum grease is usually applied to the flanges. Once the air is pumped out, the stopcock on the desiccator can be turned to seal it off from the pump and thereby retain the interior vacuum. When the stored samples are required, the stopcock is rotated to allow entry of air (or an inert atmosphere) thereby making it possible to open the formerly evacuated chamber. This kind of desiccator is almost always used when the samples to be stored must be kept as dry as possible or if the stored samples could be harmed by contact with air. xcen>fr RGoogle
