The population of any region is characterised with respect to its growth rate. Exponential and Logistic growth models are two typical but important growth models that can be used to track the population's growth rate. Exponential growth is characterised by the rapid expansion of the population that is unaffected by any upper limit. Contrarily, logistic growth refers to a sustainable growth rate that has an upper limit of growth. The exponential growth model depicts an indefinite growth … [Read more...]
Difference Between Vitamins and Minerals
An overall physical and psychological growth necessitates the right amount of nutrients in the form of a balanced diet. Similarly, vitamins and minerals also have their own significance in the existence of the living system. Vitamins on one side are the organic components that are manufactured within the living bodies of microorganisms, plants, and animals. Whereas minerals being inorganic in nature, are naturally obtained from soil, rocks, water etc. Vitamins are fragile and susceptible … [Read more...]
Difference Between Meristematic and Permanent Tissue
Just like animals, plants too have a unique and complex living pattern that is made possible by the numerous tissues making up their body. Plant tissues are classed as meristematic or permanent based on their structure, location, orientation, and function. Meristematic tissues are made up of identical types of cells that are constantly diving, differentiating, and developing. Contrarily, permanent tissues are composed of cells that have lost their potential of division and are already … [Read more...]
Difference Between Sterilization and Disinfection
Following the covid eruption, you may have come across the terms disinfection, sterilization, and even sanitisation at regular intervals. All of these phrases refer to antimicrobial procedures aimed at eradicating pathogenic microorganisms and other infectious agents. Disinfection is a common and simple method of decontamination that we employ on a daily basis. On the other hand, sterilization is predominantly linked with medical, industrial, and scientific areas and is not performed very … [Read more...]
Difference Between Natural and Artificial Ecosystem
Ecosystems, whether natural or artificial, both rely on the cosmic principles of nature. However, there are other differences between these two systems, including creation, purpose, diversity, susceptibility, sustainability, etc. The natural ecosystem is the outcome of the constant interplay between living and non-living organisms, as well as the environment in which they live. Humans, on the other hand, create artificial ecosystems for their own advantage. The living and non-living … [Read more...]
Difference Between Producers and Consumers
The meaning of producer and consumer is obvious and evident from their names themselves. Producers, in general, are those who create something, whereas consumers are those who utilize something. The term 'Producers' is used in biology to describe the living entities that have the potential to produce food from natural elements like sunlight, carbon dioxide, water, etc. The 'Consumers,' on the other hand, are those living beings that rely on the producers or the other lesser consumers for … [Read more...]
Difference Between PCR, RT-PCR and qPCR
The key difference among PCR, RT PCR and qPCR is the beginning genetic material, i.e. the template used for the reaction. DNA as a template is utilised in fundamental PCR, whereas RT PCR permits only RNA to be used as a template. On the other hand, qPCR is capable of using both DNA and RNA as templates. PCR and RT PCR techniques can only determine the presence or absence of a specific genetic fragment in a sample. However, qPCR has the competence to not only indicate the absence or presence … [Read more...]
Difference Between Gap Junction and Tight Junction
The essential difference between the Gap junction and the Tight junction is that the first one is known to direct channel between cytoplasms of the adjacent cells, while the latter blocks the passage of solutes and water molecules between epithelial layers in vertebrates. Gap junctions are widely spread in the body of vertebrates, while tight junctions are only found in epithelial cells of the vertebrates. The social interactions among the cells of the multicellular organism are the most … [Read more...]
Difference Between Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD)
Biochemical Oxygen Demand (BOD) is the measurement of the amount of oxygen consumed by aquatic microorganisms to decompose or to oxidize the organic matter. On the other hand, Chemical Oxygen Demand (COD) refers to the amount of oxygen needed to break down the pollutants chemically. BOD and COD are correlated, as both are the methods with the aim of indicating the amount of pollution present in a given water sample. However, BOD is widely used due to some practical reasons, but the analysis … [Read more...]
Difference Between Protozoans and Metazoans
The significant difference between the Protozoa and Metazoa is that the Protozoans are single-celled, though the Metazoans are multicellular. Secondly, the former one (Protozoa) belongs to the primitive type while the latter (Metazoans) belongs to the developed type of animal kingdom. Along with the variations in these two, there are few similarities also like, both the Protozans and the Metazoans are the Eukaryotic, which means they have well-defined organelles within the cell, that perform … [Read more...]
