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...]
Difference Between Lytic and Lysogenic Phase
The main difference between the two life cycles followed by the phage during the infection to the bacterium is that in the lytic phase the phage infects the machinery of the cell to make more of its components, and later they lyse, or destroy, the cell, and releases new phage particles. However, in the lysogenic phase, the phage does not destroy the host cell; instead, they insert their genetic material with the chromosome of the host cell, which replicates it as a unit. Bacteriophage or … [Read more...]
Difference Between Creepers and Climbers Plants
Creepers and Climbers are plants with weak stems and hence cannot grow erect, so, they grow with the support of either an object or horizontally along with the soil. 'Creepers' as the name says, expand horizontally along with the soil, whereas 'climbers' grow erect by holding up any object. There are many examples of these types of plants, like watermelon is creeper while grapes are climbers. Although there are some pants like 'Vine' that can be either creeper or climber. Indeed, many of … [Read more...]
Difference Between Binary Fission and Budding
Binary fission is seen in algae and in few protozoans where there is the division of the nucleus of the cell in the cyst (protective covering), and further, the cyst breaks, and two new offsprings are released. Budding is another kind of asexual reproduction, where a bulb-like projection occurs from the parent body called the bud, which gets detached and forms a new individual. This is seen in Hydra. Reproduction is the process, through which living organisms can produce new ones of their … [Read more...]
Difference Between Tubectomy and Vasectomy
Tubectomy is the sterilization process in the female that prevents the passage of eggs from reaching the uterus for implantation, and it is a small incision technique. Vasectomy is the sterilization process of the male that prevents the passage of sperms, and it is also the small incision technique. These two methods are known as permanent methods of sterilization or contraception. These methods are advised to any one of the partners either male or female as a way to prevent any more … [Read more...]
Difference Between Lyophilic and Lyophobic Colloids
The solvent-loving colloids or such colloids which show less or distinct affinity towards dispersion medium is known as Lyophilic colloids. The solvent-hating colloids or such colloids which do not have any attraction towards dispersion medium is known as Lyophobic colloids. The colloidal state is said when the particle size is between 1 to 100 nm. When the particle size is less than 1nm it is in the true solution, while when the particle size is more than 100 nm, the matter exists in the … [Read more...]
Difference Between Auxin and Gibberellin
The type of plant hormone that controls the cell elongation in plants during phototropism and gravitropism is known as Auxin. Another type of plant growth hormone 'Gibberellin' regulates the seed germination shoot elongation, flower, and fruit maturation. Such important biochemicals that influence plant growth and cell differentiation, tissues, and organs under various conditions are known as Plant hormones. The term was elaborated by the German botanist 'Julius von Sachs' who pointed out … [Read more...]
Difference Between Purines and Pyrimidines
The two types of nitrogenous bases 'Purines and Pyrimidines' differ in their structure. Purine is composed of an organic ring having two nitrogen and four carbon atoms fused with an imidazole ring, whereas pyrimidine structure is similar to that of benzene having two nitrogen and four carbon atoms only. Purines and Pyrimidines are very known as the backbone for the formation of DNA and RNA. These are the aromatic heterocyclic compounds, present in cells and are involved in protein synthesis, … [Read more...]
Difference Between Glucose and Fructose
Glucose and fructose are the simple sugars, with the same molecular formula 'C6H12O6'. Glucose is the aldohexose, while fructose is ketohexoses. Fructose is commercially used as sweeteners in the food and beverages industries. The table sugar or sucrose is made up of fructose and glucose. Usually, our body also absorbs this type and is used to produce energy by the cells. The most preferred source of energy by the researchers is glucose for our body. Likewise, glucose, fructose does not … [Read more...]
