Protochordates vs Euchordates Protochordata and Euchordataare two major groups of Phylum Chordata; therefore, before learning the difference between Protochordata and Euchordata, let us first briefly discuss Chordata. Chordates are the most advance and probably the most well-known group of organisms in the entire animal Kingdom including humans. They are bilateral, deuterostomial eucoelomates. The most […]
Difference Between Aquatic and Terrestrial Animals
Aquatic vs Terrestrial Animals The fundamental difference between aquatic and terrestrial animals is their habitat and their adaptation to that habitat. Almost all the habitats found in the world can be put into two major habitats; aquatic and terrestrial. Aquatic ecosystems are found in water bodies and can be categorized into two broad groups; […]
Difference Between Platyhelminthes and Nematoda
Platyhelminthes vs Nematoda Platyhelminthes and Nematoda are two major invertebrate phyla in the Kingdom Animalia that show some difference between them in terms of their morphology. Invertebrates are the animals who lack backbone. The other major invertebrate phyla include Porifera, Cnidaria, Annelida, Arthropoda, Mollusca, and Echinodermata. Platyhelminthes and nematodes are non-coelomates and have very […]
Difference Between Gene and Trait
Gene vs Trait Since gene and trait are two intertwined terms used in genetics but not the same, we must be very clear with the difference between gene and trait. Briefly, genes have the information, which determines the formation of proteins in the body. These proteins ultimately design the structure of all organisms. Thus, genes determine the characteristics (traits) […]
Difference Between Breathing and Cellular Respiration
Breathing vs Cellular Respiration Though, in physiology, there is a well defined difference between breathing and cellular respiration, many people used think that respiration and breathing are two equal terms to describe the oxygen intake and carbon dioxide elimination that take place in the respiratory system. In physiology, respiration has an extensive meaning. In […]
Difference Between Synthesis and Decomposition
Synthesis vs Decomposition Difference between synthesis and decomposition has a high scientific value as synthesis and decomposition are one of the most important types of chemical reactions to occur in the nature. A chemical reaction is defined as the formation or breaking of chemical bonds between atoms to form new combinations of atoms. The […]
Difference Between Terminal Hair and Vellus Hair
Terminal Hair vs Vellus Hair Terminal hair and vellus hair being two types of hair, knowing what is hair is useful for a better understanding of the difference between terminal hair and vellus hair. The presence of hairs is considered as unique mammalian characteristic feature. Hairs (hair fibers) are dead structures formed of keratin proteins […]
Difference Between Sebaceous and Sweat Glands
Sebaceous Gland vs Sweat Gland Though both, sebaceous glands and sweat glands, are found in the dermis of the mammalian skin, there are differences between sebaceous and sweat glands in a number of ways, which will be discussed in this article. Gland is a group of cells or an organ that have the ability to […]
Difference Between Marsupial and Rodent
Marsupial vs Rodent The key difference between marsupials and other mammals including rodents is the embryonic development pattern. Knowledge about mammals, in general, would be helpful in understanding the difference between these two mammals, marsupials and rodents. About 220 million years ago, first mammalian species evolved and they reached their maximum diversity in the Tertiary […]
Difference Between Keratinocytes and Melanocytes
Keratinocytes vs Melanocytes To understand the difference between keratinocytes and melanocytes, one must first understand the anatomy of skin. Skin is the largest organ of the body and acts a mechanical barrier between the underlying tissues and the external environment. Skin is mainly composed of two layers; outer- protective epidermis and inner-connective dermis. Epidermis […]
