The difference between acids and bases is mainly due to the following factors:- pH value: Different compounds are having different pH values (1-14), depending upon their chemical nature. The compounds that are having pH less than seven are termed acidic substances, while the compounds that are having a pH of more than seven are termed …
Biosphere reserves are one of the methods of in-situ biodiversity conservation, which are the largest protected area covering more than 5000 sq. km. These cover more land area than the other methods (National parks and wildlife sanctuaries) of the in-situ biodiversity conversation. They are also termed “Biodiversity reserves“. It conserves biodiversity by protecting plant, animal …
Nutrition in bacteria is primarily categorized into two major groups, namely autotrophic and heterotrophic. Classification of bacteria in terms of nutritional requirement typically depends on the energy sources, whether in the form of light or chemical energy. Some bacteria obtain energy directly from the sunlight. However, a few bacteria get chemical energy by utilizing inorganic …
The pH scale is a measurement of the acidic or basic behaviour of the aqueous solution. It clearly denotes the compounds as acidic and basic, when these have pH between 0-6 and 8-14, respectively. A pH scale is an important tool for differentiating the acidic and alkaline products, depending on the colour change that varies …
Plant Growth Regulators are the chemicals derived naturally by the plants, which function is to regulate the length and thickness of plants. PGRs are molecules that can influence or inhibit plant growth. It is also called “Phytophormones” that are generally active at very low concentrations. The PGRs are sometimes referred to as a natural regulator, …
Organic matter decomposition is an ecological process that returns nutrients to the soil. The decomposition process has two stages one is on the soil, and the second is below the ground. In the first stage, several terrestrial animals and insects above the ground feed on dead leaves and animal residues left over the ground. Here, …
The anagen phase is the first stage of the hair life cycle. It is the prolonged phase of the hair growth cycle that lasts for months to years. Cells at the base of the follicle actively divide and multiply during this phase to build up a hair strand. Hair follicles are the hair-forming factories present …
What are the examples of endergonic reactions? Well, before proceeding to that, let’s understand what an endergonic reaction is. It is an energy-absorbing process. Cells undergoing endergonic reactions need free energy from outside to perform any task. Thus, endergonic reactions are always nonspontaneous. Non-spontaneity of the reaction is when the system is unable to move …
What is the difference between 70-S and 80-S ribosomes? They are classified based on their sedimentation rate. ‘S’ is the non-SI metric unit, expressed as Svedberg’s Unit, that denotes the sedimentation coefficient of the ribosomes. The particle size of ribosomes in prokaryotic and eukaryotic cells differs, due to which they sediment at different rates when centrifuged. …
What are the layers of the hair shaft? The answer is there are three layers in the hair shaft; the medulla, cortex and cuticle. The medulla is the deepest layer of hair seen only in thick hairs. The cortex is the central layer of the hair shaft, giving strength, shine, colour and texture to your …
