The five senses of the human body include vision, hearing, touch, taste and smell. The human body has specific sensory organs for each of these senses. The five basic sensory organs are the eyes, ears, skin, tongue and nose. These sensory organs play a major role in signalling information to the brain and help us …
Diffusion is a process that we experience in our daily life. It is a movement of molecules, ions or gases from a region of high concentration to an area of low concentration. For diffusion to occur, there must be a concentration gradient between the two areas. A concentration gradient potentially excites molecules to move in …
Abiotic factors are the ones with the non-living origin but have a major influence on the living organisms associated with the ecosystem. These include physical components like air, water, light, soil, temperature etc. We can define the term abiotic by breaking it into ‘A‘ (means without) and ‘Biotic‘ (means life). Abiotic factors can be physical …
Endosmosis is the diffusion of water from the cell exterior to the cell interior or cytoplasm. The study of endosmosis is possible if you keep a cell in the hypotonic solution. In endosmosis, the solute and solvent concentration inside and outside the cell are as follows: High solvent and low solute concentration in the cell …
The difference between mules and horses relies upon their parents and fertility. Horse and Mule belong to the same family, ‘Equidae’ and more or less they look very similar. But, both the creatures have different physical and genetic traits that we will discuss in this post. A mule is an animal created by breeding donkeys …
A study of osmosis can be done using a potato osmometer. Osmosis is a phenomenon in which water moves from high solvent to low solvent concentration. The movement of water occurs between two compartments, separated by a semipermeable membrane. The cell membrane of living organisms behaves as a semipermeable or selective membrane. The permeability of …
Digestive glands in the human body play an important role in food digestion. These are associated with the alimentary canal to aid the process of digestion. The salivary gland, liver and pancreas are the accessory digestive glands. Gastric and intestinal glands are the digestive glands present in the lining of the stomach and small intestine. …
Retrogradation of starch is just opposite of the starch gelatinization. Here, the term retrogradation denotes the reversal mechanism. The gelation of starch contains disaggregated starch molecules. But, the disaggregated amylose and amylopectin chains realign during retrogradation of a starch gel. We could see the retrograde starch after a long-term cooling or storage of the starch …
The difference between axon and dendrite lies in their shape and branching. As well as, they differ in their length and function. Axons and dendrites are the cytoplasmic projections of the nerve cell body. Both play an essential role in the conduction of nerve impulses. Shape: Axons maintain a constant radius. Whereas, dendrites are thicker near …
Starch gelatinization is a phenomenon in which the starch granules primarily absorb water, swell and eventually burst out to form a gel in the presence of water and heat. Gelatinization of starch is a method that requires starch (any sources like cornstarch, rice flour etc.) as a solute and water as a solvent. Here, water …
