Flora Definition The term ‘flora’ is defined as all the naturally occurring native plants of a particular region. Flora indicates all forms of plant life, more generally used to represent the plant life of a particular place. Sometimes, the term ‘microflora’ or ‘gut flora’ is used to represent the naturally occurring microorganisms, mainly, bacteria and … Read more 12 differences between Flora and Fauna (Flora vs Fauna)
Epithelial Tissue Definition Epithelial tissue is a type of animal tissue, consisting of closely aggregated polyhedral cells connected firmly to one another in the form of cellular sheets that line the interior of hollow organs and cover the body surface. Cells in epithelial tissue or epithelium (epithelia; plural) are arranged in continuous sheets, in either … Read more 15 differences between epithelial tissue and connective tissue
Image Source: Helixitta and Christopherrussell. Endonuclease Definition An endonuclease is a group of enzymes that cleave the phosphodiester bond present within a polynucleotide chain. Endonucleases are capable of breaking the bond from the middle of a chain. These enzymes are either specific or non-specific to the sequences being cleaved. The endonucleases that are specific to … Read more 11 differences between Endonuclease and Exonuclease
Image Source: BioNinja. Diploid Definition Diploid is a cell or organism that has paired chromosomes, one from each parent. In most organisms, the somatic cells are diploid, whereas the sex cells tend to be haploid. The diploid cells have two homologous copies of the two chromosomes obtained from two parents. Almost all mammals are considered … Read more 12 differences between Diploid and Haploid (Diploid vs Haploid)
Communicable diseases definition Communicable diseases are the diseases that are caused by infectious agents and can be transmitted from an infected person to other people, animals, or other sources in the environment. Communicable diseases are also called infectious diseases or transmissible diseases. These diseases are transmitted when the infectious agents are transmitted through contact with … Read more 17 differences between communicable and non-communicable diseases
Cold-blooded animals definition Cold-blooded animals are the animals that are not capable of regulating their body’s temperature according to the temperature of the surrounding. The body temperature of these animals fluctuates as they move in different surroundings with different temperatures. Thus, they do not have a constant body temperature. Because of this reason, these animals … Read more 16 differences between Cold-blooded and Warm-blooded animals
Celsius scale definition Celsius scale, or centigrade scale, is a temperature scale that is based on the freezing point of water at 0°C and the boiling point of water at 100°C. The scale was introduced by and also named after the Swedish astronomer Anders Celsius in 1742 A.D. This scale uses the symbol °C. Initially, … Read more 10 Differences between Celsius scale and Fahrenheit scale
Chromosome Definition A chromosome is a thread-like structure present in the nucleus or nuclear region of the cytoplasm that is made up of a single molecule of DNA (Deoxyribonucleic acid) and proteins, carrying some or all genetic materials of an organism. These chromosomes are only visible under the light microscope during the metaphase of the … Read more 11 differences between Chromosome and Chromatid
Cation Definition A cation is an atom or a group of atoms bearing one or more positive electric charges. Cations are formed in various ways, some of which are: When electrons are removed from neutral atoms or ions or other molecules. By the combination of positive ions with other molecules. By rupture of covalent when … Read more 10 differences between Cation and Anion
Bone Definition A bone is a connective tissue where the living cells, tissues, and other components are enclosed within hard non-living intercellular material. The two important constituents of bone are collagen and calcium phosphate that distinguish it from other similar structures like the enamel and chitin. Bone tissues together make up the human skeleton system … Read more 15 differences between Bone and Cartilage
