Southern blotting is the first detection technique which is used to identify the specific DNA sequences in the provided tissue or blood sample and is named after the scientist who developed it, 'Ed Southern in the year 1975. Northern blotting is the technique used to know the gene expression of the provided sample by identifying the specific RNA or mRNA molecules; it was developed by David Kemp, James Alwine and George Stark in 1977 at Stanford University. Western blotting is a sensitive … [Read more...]
Difference Between Afferent and Efferent Neurons
The afferent or sensory nerve transfers the messages or signals from various organs to the spinal cord or brain. In contrast, efferent nerve or motor nerve transfer the messages or signals from the spinal cord or brain to multiple organs. That means their role is opposite, but they work in transferring signals between organs and spinal cord or brain. When you rub your palms, do exercises, hit a ball, there is the involvement of afferent and efferent neurons that are responding to the … [Read more...]
Difference Between Scavenger and Decomposer
Scavenger is the organisms that break apart the dead and decayed matter into smaller particles. In contrast, decomposer is such organisms that further break-down or decompose the dead matter (dead plants and animals). As a result, they provide nutrients to the soil by producing products such as nitrogen, phosphorus, calcium. Therefore we can say that scavengers are the one who initiates the consumption of the dead matter and the decomposers finish it, and provide nutrients back to the soil; … [Read more...]
Difference Between Binary and Multiple Fission
Both types of fission are the types of asexual reproduction, in which the binary fission give rise to two daughter cell from the parent cell, whereas in multiple fission, the parent cell gives rise to numerous daughter cell. Binary fission is one of the most common methods of reproduction in the prokaryotes, while multiple fission occurs in some parasitic species and protists. Generally, in biology, one of the basic of the critical concepts is 'reproduction'. It gives the knowledge of how the … [Read more...]
Difference Between Bioreactor and Fermenter
A system in which the organisms are cultivated and provoked to produce the desired products is called a bioreactor. In contrast, the fermenter is the system used for the fermentation process to produce the desired outcomes. Mainly in the bioreactor, plant and animal cells are used, while fermentation is limited to microbial use only. These are types of closed- system/ vessels that are used for the particular type of biochemical reaction, where, in the bioreactor, various kinds of biochemical … [Read more...]
Difference Between Kwashiorkor and Marasmus
Kwashiorkor is the severe protein deficiency in the children, while marasmus is the severe deficiency of the nutrients and insufficient intake of calorie. This is the primary difference between the two. Protein-energy malnutrition (PEM) or Protein-calorie malnutrition (PCM) is the result of the deficiency of the carbohydrates, fats and especially proteins. The above two diseases, which are kwashiorkor and marasmus, are the commonest among such deficiencies and is frequently occurs in infants … [Read more...]
Difference Between Blood and Lymph
Blood is the type of connective tissue found in our body and plays a significant role in transporting various substances to different parts of the body. Lymph is the white colour fluid tissue, made up of white blood cells and lymphocytes and plays a significant role in carrying the white blood cells to and from the bones and lymph nodes. Secondly, Blood plays a leading role in carrying oxygen and carbon dioxide. At the same time, Lymph is a part of the body's immune system works in defence … [Read more...]
Difference Between Molecules and Compounds
When the chemical bonds unite any atoms (two or more) is known as a molecule. But such type of molecules that consist of different atoms (two or more) of different chemical elements are known as compounds. However, it is a fact that all compounds are molecules, but all molecules are not compounds. So, we can say that any combination of atoms is a molecule, but when the combination of atoms is from different elements, it is known as the compound. Let's take an example to understand in a better … [Read more...]
Difference Between Carpel and Pistil
Carpel and Pistil are the reproductive part of a flower in a plant, and they have a very slight difference between them. As carpel is composed of the stigma, style and ovary, while pistil is the union of the carpels or it can be the single carpel, so we can say that pistil is the fusion of carpels. One can easily distinguish the number of carpels by checking the number of styles. In contrast, the number of pistils can be identified by the presence of the number of ovaries in flower. The … [Read more...]
Difference Between Hydroponics and Aquaponics
When the plants are grown with the medium like sand, gravel or water but without soil is known as hydroponics. On the other hands, aquaponics is considered as the subset of the hydroponics, where the plants are grown in water, (without soil), and nutrients are provided from the by-products of fishes. We all are aware of the process known as photosynthesis, where the plants produce oxygen and energy in the form of glucose, by using sunlight, water and other chemicals, but there is no … [Read more...]
