Radial vs Bilateral Symmetry Symmetry, the balanced distribution of duplicate body parts, is a prominent feature in biological organisms, especially animals; but plants too exhibit interesting symmetrical features. The symmetry of animals has a long history with its existence prevails in many taxonomic phyla. Radial symmetry and bilateral symmetry are the two main types […]

Difference Between Continental Drift and Plate Tectonics
Continental Drift vs Plate Tectonics Continental drift and plate tectonics are two theories explaining the geological evolution of the earth, specifically its crust. Continental Drift Continental drift is a theory first presented by Abraham Ortelius (Abraham Ortels) in 1596. The concept was independently developed by German geologist Alfred Wegener in 1912. The theory states […]
Difference Between Relation and Function
Relation vs Function From high school mathematics onwards, function becomes a common term. Even though it is used quite often, it is used without proper understanding of its definition and interpretations. This article focuses on describing those aspects of a function. Relation A relation is a link between the elements of two sets. In […]
Difference Between Peak to Peak and RMS
Peak to Peak vs RMS Peak to Peak and RMS amplitudes are two measures of an alternating signal/source. Peak to peak amplitude is measured from the signal and RMS value has to be derived from the measurements. Peak to Peak Peak amplitude is the maximum amplitude obtained by a signal/source in a given interval. […]
Difference Between Light and Radio Waves
Light vs Radio Waves Energy is one of the primary constituents of the universe. It is conserved throughout the physical universe, never created or never destroyed but transforming from one form to another. Human technology, primarily, is based on the knowledge of methods to manipulate these forms to produce a desired outcome. In physics, […]
Difference Between Dorsal and Ventral
Dorsal vs Ventral In anatomy, the directional terms are of great importance, especially in understanding the locations and positions of organs and organ systems inside the body of any animal. The most important and the main directions that are essential in understanding the anatomy of animals are anterior – posterior, left – right, and […]
Difference Between Simple and Compound Leaves
The key difference between simple and compound leaves is that the leaf blade of the simple leave is undivided while the leaf blade of a compound leaf has several leaflets. Leaf is the most important photosynthetic structure in green plants. Furthermore, characteristics of the leaf are useful in identification of plant genera and species. According […]
Difference Between Neutrophils and Macrophages
The key difference between neutrophils and macrophages is that neutrophils are not antigen presenting cells while macrophages are antigen presenting cells. Neutrophils and macrophages are leucocytes which belong to the innate immune system, and they act as the main initial defenders against pathogens. These specialized cells can squeeze through the small holes of blood vessels […]
Difference Between Abiogenesis and Biogenesis
Abiogenesis vs Biogenesis The origin of life is a controversial topic and also it has a long history. Ancient people believed that the origin of life is a spontaneous mechanism and occurs due to nonliving substances. This opinion was known as “Abiogenesis”. However, finally scientists proved that the origin of life is actually caused […]
Difference Between Metaphase 1 and 2
The key difference between metaphase 1 and 2 is that in metaphase 1, homologous chromosomes pair up at the metaphase plate while in metaphase 2, single chromosomes line up at the metaphase plate. Meiosis is the process that converts a diploid cell into four haploid cells during the gamete formation. It is an important process […]
