The key difference between acetylcholine and adrenaline is that acetylcholine is a neurotransmitter in both peripheral and central nervous systems in many organisms, while adrenaline is a hormone that helps to react quickly in a stressful situation. Acetylcholine and adrenaline are two important molecules produced in our body. Acetylcholine is a neurotransmitter that mediates nerve […]
Difference Between Acidophiles Neutrophiles and Alkaliphiles
The key difference between acidophiles neutrophiles and alkaliphiles is that acidophiles are microorganisms that grow at a pH near to 3 while neutrophiles are microorganisms that grow at a pH near to neutral or 7 and alkaliphiles are microorganisms that grow well between the pH of 8 to 10.5. Microbes need certain conditions for their […]
Difference Between Fermentation and Putrefaction
The key difference between fermentation and putrefaction is that fermentation is a metabolic process where microorganisms, especially yeast and bacteria, convert sugar into acids, gasses and alcohols while putrefaction is the decay of organic matter by microorganisms, which results in the formation of compost and a foul smell. Fermentation and putrefaction are two processes carried out by […]
Difference Between Reciprocal Altruism and Kin Selection
The key difference between reciprocal altruism and kin selection is that reciprocal altruism occurs between two unrelated individuals, while kin selection occurs between closely related organisms. Altruism refers to any behaviour that reduces an individual’s fitness, but in return, it increases the fitness of other individuals. In altruism, other individuals benefit at the expense of the […]
Difference Between Ametabolous and Hemimetabolous
The key difference between ametabolous and hemimetabolous is that ametabolous refers to insect development in which there is no metamorphosis while hemimetabolous refers to insect development in which there is incomplete or partial metamorphosis. Metamorphosis is a series of events by which insects develop, grow and change the form. In simple words, it is the series […]
Difference Between Hymenoptera and Diptera
The key difference between Hymenoptera and Diptera is that Hymenoptera insects have two pair of wings while Diptera insects have one pair of wings. Phylum Arthropoda is one of the major phyla in Kingdom Animalia. This phylum consists of animals that possess hard exoskeletons and joined appendages. It is the largest phylum comprising a wide […]
Difference Between Mycobacterium Tuberculosis and Nontuberculous Mycobacteria
The key difference between Mycobacterium tuberculosis and nontuberculous mycobacteria is that Mycobacterium tuberculosis is the causative agent of tuberculosis while nontuberculous mycobacteria are causative agents of lung diseases, but they do not cause tuberculosis. Mycobacterium tuberculosis and nontuberculous mycobacteria cause chronic lung infections. However, Mycobacterium tuberculosis causes tuberculosis which transmits from person to person from […]
Difference Between Abiogenesis and Spontaneous Generation
The key difference between abiogenesis and spontaneous generation is that abiogenesis is the theory that states all life started from inorganic molecules while spontaneous generation is the theory that states complex life arises spontaneously and continually from nonliving matter. Abiogenesis and spontaneous generation are two theories that attempt to describe how life on Earth has […]
Difference Between Intrasexual and Intersexual Selection
The key difference between intrasexual and intersexual selection is that intrasexual selection refers to sexual selection within the members of the same sex to access mates while intersexual selection refers to sexual selection which occurs between two sexes when members of one sex choose the members of the opposite sex. Sexual selection is a mode […]
Difference Between Volvox Paramecium and Euglena
The key difference between volvox paramecium and euglena is that volvox is a green alga that lives as colonies in freshwater while paramecium is a ciliate protozoan that resembles the shape of a shoe and euglena is a single-celled flagellate eukaryote which has both plant and animal features. Kingdom Protista consists of diverse eukaryotic single-celled […]
