The WBC or leukocyte count method estimates white blood cells per microlitres of your blood. By enumerating the total number or concentration of leukocytes, you could determine the condition of your immune health. The average WBC count is between 4000 to 11000 cells/µL of blood. An increase in the concentration of leukocytes leads to a …
Chemical disinfectants either destroy, inactivate or inhibit the pathogenic growth. Disinfection eliminates various microbes, except for bacterial spores, using different chemical agents, heat or radiation. It disinfects the inanimate objects. Disinfection is classified into low-level, intermediate-level or high-level. Low-level disinfection is efficient in killing vegetative bacteria and lipid-containing viruses. Intermediate-level disinfection effectively kills bacteria, fungi …
The difference between monocot and dicot stem is mainly in the arrangement and type of the vascular system. Vascular structures in the stem facilitate the upward and downward flow of water and nutrients from the root to the leaves and vice versa. The vascular bundles in the monocot stem are dispersed, whereas the monocot stem …
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 …
The allosteric site of an enzyme is regulatory in function. Enzymes with allosteric or regulatory sites behave as the “Allosteric enzymes”. Such enzymes possess multiple binding sites for both substrates and effectors. Allosteric enzymes are regulated by the non-covalent or reversible binding of effectors or non-substrate molecules to the allosteric site. Thus, the allosteric site …
Euglena eyespot is also called stigma or eyespot apparatus. It generally has a bright red colour appearance. Euglena is a unicellular photosynthetic organism having an eyespot apparatus as a light-receptive organelle. The red colour of the eyespot in Euglena is due to the presence of carotenoid pigment granules. In addition, it contains photoreceptors, structural, metabolic …
The difference between vitreous humour and aqueous humour is primarily in the location within the eye. Vitreous humour is a gelatinous mass occupying the vacant space within the eye lens and the retina. Aqueous humour is a watery fluid occupying the cavity within the cornea and the eye lens. The eye-cavity has distinct two chambers, …

The hydrological cycle is also called the water cycle, the global water cycle or the hydrologic cycle. It explains the water-cycling mechanism through the earth’s biosphere. The physical state of water has three phases, namely solid (glaciers, ice sheets etc.), liquid (oceans, rivers, lakes, ponds etc.) and gas (water vapours). The water cycle has four …
Cloud formation can be seen in the earth’s homosphere. Nephology is the science of clouds. Clouds form by the condensation of water vapours into water droplets or ice crystals. Stratus, cirrus, stratocumulus, cumulus and cumulonimbus are common types of clouds in the troposphere, stratosphere and mesosphere. Clouds in the stratosphere and mesosphere regions appear as …
The physical state of water has three phases (solid, liquid and gas), depending upon the factors like hydrogen bonding, temperature and pressure. Water is a polar inorganic compound that serves as a universal solvent. It has a neutral pH in a pure state. The melting point of water is 0 degrees Celsius, and the boiling …
