What is Ebola ? Ebola is a virus that causes a severe and often fatal disease in humans and nonhuman primates (such as monkeys, gorillas, and chimpanzees). The virus is named after the Ebola River in the Democratic Republic of Congo (formerly Zaire), where it was first identified in 1976. Ebola is a viral hemorrhagic … Read more
What is Archaea? Characteristics of Archaea Archaea are single-celled microorganisms that belong to the prokaryotic domain of life and share some characteristics with bacteria. However, they also possess unique features that distinguish them from bacteria. The main characteristics of Archaea include: These characteristics make Archaea unique and important microorganisms in the study of the evolution … Read more
Multicellular organisms experience a variety of cell development and death processes. Cellular death is crucial for the survival and development of all organisms. Our body is made up of several cell types situated in diverse body sections. There are two distinct methods by which a cell dies. Either the organism is exposed to an unfavourable … Read more
What is Cilia? What is Microvill? Difference between Cilia and Microvilli Cilia Microvilli Epithelial cells generate cilia, which are elongated, hair-like structures. Microvilli are epithelial cell-derived membrane protuberances. Cilia develop from basal granules. Basal granules are lacking in microvilli. Cylindrical cilia with tapered ends. Microvilli are cylindrical and terminate in blunt tips. Microvilli are shorter … Read more
Both microtubules and microfilaments are components of a cell’s cytoskeleton. Microtubules, microfilaments, and intermediate filaments compose the cytoskeleton. Tubulin proteins are polymerized to produce microtubules. They provide the cell with mechanical support and help to intracellular transport. Polymerization of actin protein monomers produces microfilaments. They contribute to the mobility of the cell on the surface. … Read more
Taenia solium and Fasciola hepatica are parasitic flatworms belonging to two different groups. T. solium is a cestode (pork tapeworm) having a long and segmented body. The adult worm is present in the small intestine of humans, while pig acts as its major intermediate host. Infection with T. solium can occur in different forms. Undercooked … Read more

What is Cladogram tree? What is Phylogenetic tree? Cladogram vs Phylogenetic tree Cladogram Phylogenetic Tree Represents evolutionary relationships based on shared derived traits (synapomorphies) Represents evolutionary relationships among organisms or groups of organisms Focuses on identifying and grouping organisms based on shared characteristics Represents the pattern of descent and the evolutionary history of species or … Read more
