Vegetative reproduction.Bulbil is a small bulblike organ of vegetative reproduction growing in leaf axils or on flower stalks of plants such as the onion & tiger lily. The bulbils drop from the parent plant on to the ground, give out adventitious roots & develop into new plants. It is a reproductive organ that takes part in vegetative reproduction.
Cyanobacteria.Cyanobacteria, also known as blue algae, are singlecelled & belong to the family of Prokaryotes. The ability of cyanobacteria to perform oxygenic photosynthesis is thought to have converted the early reducing atmosphere into an oxidizing one, which dramatically changed the composition of life forms on Earth by stimulating biodiversity & leading to the nearextinction of oxygen-intolerant organisms. That means, they do not have a cell nucleus.
20.2015, Morphine is the predominant alkaloid found in the varieties of opium poppy plant. It is obtained in form of liquid from the fruit capsule of the poppy. The latex which oozes from the incisions is collected, & dried to produce 'raw opium' (about 8-14% morphine by dry weight).
localised growth.Plants produce new cells & grow only in their shoot & root apical meristems & leaf primordia; this is localized growth. From the time we are embroys until we are about 18 yrs old, all parts of our body grow simultaneously. In contrast, all parts of an animal's body grow (diffuse growth). Due to a plant's localized growth, an individual plant can have older, completely mature & highly functional leaves at the same time that it is still producing new leaves.
Both (1) & (2).Eutrophication is the ecosystem response to the addition of artificial or natural substances, such as nitrates & phosphates, through fertilizers or sewage. It leads not only to increased levels of nutrients, but increased Biological Oxygen Demand as well.
endosperm.The seed includes three primary regions: the embryo, nutritive tissue, & seed coat. The endosperm may be consumed by the embryo, as in many legumes, which use the cotyledons as a food source during germination. Endosperm is a nutritive tissue that sustains the embryo & seedling.
Sulphuric acid.Battery acid is sulfuric acid that has been diluted with water to attain a 37% concentration level. These batteries use a combination of lead plates & an electrolyte consisting of a diluted sulphuric acid to convert electrical energy into potential chemical energy & back again. This particular type of acid is used in sealed lead acid batteries, however, concentration levels differentiate with some brands.
Freon.Modern refrigerators usually use a refrigerant called HFC- 134a (1,1,1,2-Tetrafluoroethane), which does not deplete the ozone layer, instead of Freon. Ammonia was also used a a common refrigerant in old refrigerators. Freon used to be the most common refrigerant till the 1980s; however, its use has declined since the 1990s as it comes under Chlorofluorocarbon (CFC). However, Freon still remains the most commonly used refrigerant. Hydrochlorofluorocarbon (HCFC), is a type of refrigerator coolant used in newer refrigerator models. The types and categories used today include HFC-134a, HCFC-142b & HCFC-22.
snakes.The ear has three main parts: the outer, middle & inner ear. The middle ear is filled with air & contains three tiny bones called ossicles - the anvil, hammer & stirrup. The outer ear consists of the pinna & the auditory canal. The inner ear contains the semicircular canals & the cochlea. Eardrum is the membrane of middle ear. Snakes have fully developed inner ear structures but no eardrum.
Glycolate.Photorespiration is a special type of respiration shown by many green plants when they are exposed to light. Other important metabolites are the amino acids glycine Glycolate (glycolic acid) is the chief metabolite of photorespiration & also its substrate.
Neonatology is a subspecialty of pediatrics that consists of the medical care of newborn infants, especially the ill or premature newborn infant. It is a hospital-based specialty, & is usually practiced in neonatal intensive care units (NICUs). The main patients of neonatologists are newborn infants who are ill or requiring special medical care due to prematurity, low birth weight, intrauterine growth retardation, congenital malformations (birth defects), sepsis, pulmonary hyperplasia or birth asphyxias.
