The key difference between sentinel and axillary lymph nodes is that sentinel lymph nodes are the first few lymph nodes into which a tumor drains while axillary lymph nodes are the lymph nodes in the human armpit which are responsible for draining lymph from the breasts and surrounding areas. The lymphatic system is the network […]
Difference Between Histopathology and Cytology
The key difference between histopathology and cytology is that histopathology is the study of diseased tissues using a microscope while cytology is the study of individual cells of the body. Cells are the basic structural units of life. During the diagnosis of diseases in medicine, cells and whole tissues are examined by pathologists. The study […]
Difference Between Euglenoids and Euglena
The key difference between euglenoids and Euglena is that euglenoids are a large group of single-cell organisms belonging to kingdom Protista while Euglena is the most widely studied representative genus of euglenoids. Euglenoids are single-cell organisms that are mostly autotrophic. They belong to kingdom Protista and show both plant and animal features. Like plants, they […]
Difference Between TATA and CAAT Box
The key difference between TATA and CAAT box is that TATA box is a conserved nucleotide region which has a consensus sequence of TATAWAW while CAAT box is a conserved nucleotide region with a consensus sequence of GGCCAATCT. TATA box and CAAT box are two regions of nucleotides that influence transcription of eukaryotic genes. They […]
Difference Between Menstrual Blood and Regular Blood
The key difference between menstrual blood and regular blood is that menstrual blood contains vaginal secretion and the endometrial cells of the uterine while regular blood is highly oxygenated and has high concentrations of hemoglobin, RBC and WBC. In forensic, blood fluids provide valuable evidence. In some instances, especially in the investigation of rape cases, […]
Difference Between Atavism and Retrogressive Evolution
The key difference between atavism and retrogressive evolution is that atavism is the sudden reappearance of ancestral characters in an individual while retrogressive evolution is the moving of species in the entire population towards primitive characters. Traits can appear or disappear over time. Throughout the evolutionary process, ancestral traits have changed or disappeared over generations. […]
Difference Between Megaloblastic and Pernicious Anemia
The key difference between megaloblastic and pernicious anemia is that megaloblastic anemia is a type of anemia in which red blood cells are larger than the normal size while pernicious anemia is a type of megaloblastic anemia that happens due to deficiency of vitamin B12. Red blood cells (RBC) are the most common type of […]
Difference Between Esca and Illicium
The key difference between esca and illicium is that esca is a fleshy growth found at the end of the illicium while illicium is a movable stalk or rod developed as a result of modification of the first spine of anglerfish. Anglerfish is a bony fish which is popular for its unique mode of predation. […]
Difference Between Transient and Balanced Polymorphism
The key difference between transient and balanced polymorphism is based on how the alleles behave. Transient polymorphism is the progressive replacement of one allele of a gene by another allele while balanced polymorphism is the maintenance of both two different alleles of a gene over time Genetic polymorphism is one or two or more variants […]
Difference Between Alpha Beta Gamma and Delta Coronavirus
The key difference between alpha beta gamma and delta coronavirus is that alpha and beta coronavirus are mainly associated with infections in mammals while gamma and delta coronavirus primarily infects birds. Coronaviruses are enveloped viruses containing positive-sense single-stranded RNA genome. They have characteristic club-like or crown-like spikes on their surfaces. Moreover, they possess a unique […]
