What is Mold? Mold is a type of fungi which is usually fuzzy in appearance and is black, brown, grey, blue, green or yellow in color. Mold is grown on surfaces which are moist, it has tubular branches having genetically identical and multiple nuclei. Not all types of mold causes health related hazards but some … Read more
Transpiration Guttation It is a process by which plants exhale water vapour through the stomata. It is a process of secretion of water droplets from the pores of vascular plants such as grass. Transpiration occurs through stomata and lenticels. Guttation occurs through Hydathodes, which are commonly found in angiosperms. In this process, only pure water … Read more
A monosaccharide is a simple sugar that constitutes the building blocks of a more complex form of sugars such as oligosaccharides and polysaccharides.The term monosaccharide etymologically means “single saccharide”. In other words, Monosaccharides are the building blocks of disaccharides (such as sucrose and lactose) and polysaccharides (such as cellulose and starch). Examples are fructose, glucose, and … Read more
1. Open MRI Scans – High-Field (1.5T) A high-field (1.5T), open MRI delivers superb image quality: Open MRI: This refers to the configuration of the equipment. The Open MRI creates a bright imaging and a relatively roomy experience because it is open on three sides. It has a modern design which yields quick and comfortable exams, which is particularly … Read more
The autonomic system is made up of two divisions, the sympathetic and parasympathetic systems. They usually work antagonistically in the organs, but in a well integrated manner. It is the balance of the actions of both divisions that maintains a stable internal environment in the body. The parasympathetic nervous system is a subdivision of the autonomic nervous system (ANS) which … Read more
The endoplasmic reticulum is the major site of synthesis in the cell. It is a system of flattened sacs (cisternae) that are continuous with the outer nuclear envelope. Its physiological function has a very close association with that of the Golgi apparatus and together, they form the secretory pathway of the cell. The endoplasmic reticulum is classified as either rough … Read more
Biodiversity is a measure of the complexity of interactions in a given habitat or ecosystem. The greater the number of species and number of interactions/complexity, the greater the biodiversity and ability of an ecosystem or habitat to survive and adapt to environmental pressures. Ecological productivity is a measure of the rate of generation of biomass … Read more
Vertebrates are animals that have a backbone inside their body. The major groups include fish, amphibians, reptiles, birds and mammals. Invertebrates don’t have a backbone. They either have a soft body, like worms and jellyfish, or a hard outer casing covering their body, like spiders and crabs. ELEMENTS OF COMPARISON VERTEBRATES INVERTEBRATES Description Vertebrates … Read more
What is Parenchyma? Parenchyma is a plant, tissue typically composed of living cells that are thin-walled, unspecialized in structure, and therefore adaptable, with differentiation, to various functions. The cells are found in many places throughout plant bodies and, given that they are alive, are actively involved in photosynthesis, secretion food storage, and other activities of plant life. Parenchyma cells can serve many functions. … Read more
