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...]

Difference Between Dopamine and Endorphins
To understand the importance of dopamine and endorphins, you must first know what are they! Our body is driven by certain chemicals that balance and manipulate the emotions we feel. Happiness, sorrow, pleasure, affection, etc. are the feelings that arise from these chemical messengers. Dopamine and endorphins are two of those same chemicals responsible for happiness and relief. Talking about dopamine, it is basically a neurotransmitter that also serves the role of a hormone. We often refer … [Read more...]
Difference Between Hypothermia and Hyperthermia
Hypothermia and hyperthermia are the situations related to overwhelmed body temperatures. Our body functions optimally around 37 °C. The body can withstand the change of a few degrees up and down, but things might start malfunctioning if the temperature fluctuates beyond that. Hypothermia, on the one hand, happens when you get exposed to a cold, wet or windy environment for a prolonged period of time. This might cause your body temperature to fall dramatically to low levels. The main reason … [Read more...]
