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...]
Difference Between Liquefied Petroleum Gas (LPG) and Compressed Natural Gas (CNG)
Liquefied Petroleum Gas or LPG is the very known name for all of you, as it is known as the cooking gas. It is one of the natural gas which can be obtained as a by-product from the processing of natural gas and petroleum refining. It consists of butane, propane and butylene. Compressed Natural Gas or CNG is widely used gas in cars, and it is also a natural gas which is obtained from methane wells, coal bed. It consists of methane. These natural gases distribution is easy for the long-distance … [Read more...]
Difference Between Homologous and Analogous Structures
Homologous structures are such structures that do not show exact similarity in their appearance and function but are linked with their common ancestor. On the other hand, analogous structures are such structures that are similar in their function and appearance but do not have any links between their ancestors. The arms of humans, legs of dogs, are the common examples of homologous structure, where they must have diverged and evolved as different beings. The wing of insects, birds, bats and … [Read more...]
Difference Between Menarche and Menopause
The onset of the first menstrual period in the female adolescent is the menarche, while the termination or end of the menstrual cycle in the females is known as menopause. These are the two significant physical and biological milestone in the female's life. The studies on these events reveal that partially genetic and partially non-genetic factors (environmental factors, lifestyle, etc.) influence the age at which menarche and menopause in females. Although there are various medical issues … [Read more...]
Difference Between Dendrite and Axon
Dendrite refers to the 'Trees' in Greek, so these are the branched small extension of the nerve cell. Axon refers to the 'axis' in Greek, so axon is the long slender like protrusion of the neuron or nerve cell. Secondly, dendrite receives messages or information or electrochemical impulses from the external environment or other neurons, so they work as the input for the neuron. The role of the axon is to send messages or any information or electrochemical impulses to the external environment … [Read more...]
Difference Between mRNA, tRNA and rRNA
mRNA has a linear structure having uracil base instead of thymine, and its secondary structure could be hairpin, stem-loop, etc. ; while tRNA has Cloverleaf structure that carries three specific stem-loops; and rRNA has much complex structure with numerous folds and loops. mRNA acts as the messenger of DNA; tRNA carries amino acids during protein synthesis; rRNA is the protein producer of the cell. These three RNA plays a vital role in the process of transcription and further in protein … [Read more...]
Difference Between Bohr and Rutherford’s Atomic Models
Niels Bohr postulates the atomic model which states that electrons move in specific circular orbits around the nucleus with quantized kinetic and potential energies. Ernest Rutherford said that an atom consists of the whole mass that is concentrated into the center. From the above statement, we can say that both the models of the atom differ in the way they explained the movements of electrons around the nucleus and their energy levels. We all are aware of the modern theory which says that … [Read more...]
Difference Between Green and White Revolution
The Green Revolution is the programme started in India and other developing countries to increase the production of wheat and rice and become self-sufficient. On the other hand, White Revolution or Operation Flood is an association with the objective of increasing milk production in India. Let's get back to history, the Third Agricultural Revolution or the Green Revolution has its birthplace in Mexico, which started in the year 1950. It is the initiatives that consist of the set of research … [Read more...]
