Glands are the ingrowth of the top layer of the skin i.e. epithelium. This ingrowth can have a tubular, simple, branched or compound formation. They are the group of cells that release a chemical substance as per the demand of the body. We can divide them into two categories- Endocrine and Exocrine. These two play a critical role in controlling the body, its growth and development and other functions. The nature of the secretion is one of the critical points to distinguishing both glands. … [Read more...]
Difference Between Chromosomes and Chromatid
The chromosome is the most condensed form of DNA, which remains packed into a thread-like structure. On the other hand, a chromatid is the one-half copy of the newly formed chromosome, joined by the centromere to the original chromosome. Secondly, the chromosomes are present every time in the nucleus of each cell and thus carry the genetic material. While chromatids form during the cellular division processes of mitosis and meiosis. We can define Genetics as the study of the genetics or … [Read more...]
Difference Between Polyp and Medusae
The phylum Cnidaria has about 13,000 different species. The cnidarians come into two basic forms - polyp and medusae. The polyps are sessile tubular-bodied organisms which remain attached to the solid anchor like rocks. The main characteristic of them is the single, circular and terminal mouth that faces upwards to the water. They are primitive organisms that lack sense organs, velum and manubrium. The tentacles of polyps are located around the mouth region, forming a ring of tentacles in the … [Read more...]
Difference Between Surface Water and Groundwater
A major difference between surface water and groundwater is the location where they are found. On one side, you may find the surface water on the external parts of the earth’s crust, i.e. on the surface level. Rivers, streams, lakes, ponds etc., are the most common examples of sources of surface water. In contrast, the groundwater is present in the interior parts of the earth’s crust, i.e. underground level. Wells, tube wells, borewells, and springs are common sources of groundwater. The … [Read more...]
Difference Between SNP and Mutation
SNP (Single nucleotide polymorphism) and mutation are both related to the structural changes in the genome. While researching, people often use these two terms interchangeably. However, scientifically, one must be very careful while using them. All the individuals except for the twins have their own version of genome sequences. These variations are mainly due to the SNPs. The chances of occurrence of SNP are approximated as one per thousand base pairs. SNP indicates the condition where one … [Read more...]
Difference Between Gas and Liquid Chromatography
Both gas and liquid chromatography serve the same purpose, i.e., separating the components of any mixture. But they vary greatly if we talk about their working mechanisms, components used and the required conditions. Gas chromatography uses gas as its mobile phase for moving the particles of the sample inside the column. In contrast, in liquid chromatography, the mobile phase used to move sample particles is liquid in nature. The principle behind gas chromatography is that it uses, … [Read more...]
Difference Between Local and General Anaesthesia
We can categorize anaesthesia into two prominent categories- local and general, based on the site and potential of action. Local anaesthesia is preferred during minor surgeries. Doctors use them when they want to numb only a particular region of your body. Even after injecting them, the patient remains conscious of his situation and can feel the other emotions. In contrast, general anaesthesia is the one used in major surgeries where multiple body parts are to be treated. These are the … [Read more...]
Difference Between Obesity and Morbid Obesity
Obesity and morbid obesity are the two health conditions where the body starts depositing excess fat. But after comparing these two conditions, you can see that they vary a lot. We can differentiate them based on many parameters like body mass index (BMI), death rate, ways of treatment etc. For an obese person, the BMI index ranges from 30 to 39. But the person suffering from morbid obesity will have BMI above 40. The chances of death are less in the case of obesity, while there is a high … [Read more...]
Difference Between Insect Pollinated and Wind Pollinated Flowers
The insect-pollinated and wind pollinated flowers highly vary in their structural appearance. The flowers are large-sized for insect pollination with vibrant bright colour petals. These flowers possess many nectar glands that continuously release the nectar. For this reason, they have a very sweet and fragrant smell. These all factors make the flower attractive for the insect to come and sit over the flower. On the other hand, there is no need to lure anybody for wind pollination. Thus, … [Read more...]
