<em>yes it is right because if we take example of viruses and germs .. new germs and viruses are much modified as compared to old ages because they adopted the ways they can escape from the immunity.. they have an adoption to transmit their DNA material ,also they can take protein coat of host because of which host's immunity cells cannot recognize germs as foriegn particle..and in this way germs and viruses remain for a long time in body due to the adoptations according to age and environment..</em>
Answer:
Dexamethasone drug in an individual lowers the level of plasma cortisol by lowering the release of Adrenocorticotropic hormone from the anterior lobe of pituitary gland.But in case of people suffering from Cushing syndrome dose of dexamethasone does not lowers the plasma cortisol level.
Explanation:
Dexamethasone is a synthetic Glucocorticoid.As a result it"s functions will be analogous to that of Glucocorticoid.Dexamethasone generally stimulate the rate of Gluconeogenesis thus increasing the production of glucose.As a result the plasma glucose level is elevated.
El Niño: an irregularly occurring and complex series of climatic changes affecting the equatorial Pacific region and beyond every few years, characterized by the appearance of unusually warm, nutrient-poor water off northern Peru and Ecuador, typically in late December.
La Niña: a cooling of the water in the equatorial Pacific, which occurs at irregular intervals, and is associated with widespread changes in weather patterns complementary to those of El Niño, but less extensive and damaging in their effects.
how they differ: La Niña is sometimes referred to as the cold phase of ENSO and El Niño as the warm phase of ENSO. These deviations from normal surface temperatures can have large-scale impacts not only on ocean processes, but also on global weather and climate. ... Typically, El Niño occurs more frequently than La Niña.
Green plants and trees use photosynthesis to make food from sunlight, carbon dioxide and water in the atmosphere: It is their primary source of energy. The importance of photosynthesis in our life is the oxygen it produces. Without photosynthesis there would be little to no oxygen on the planet.
